Timeline of the 2009 Pacific typhoon season
Pacific typhoon seasons 2007, 2008, 2009, 2010, 2011..

The 2009 Pacific typhoon season has no official bounds; it runs year-round in 2009, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 2009 Pacific hurricane season. Tropical storms formed in the entire Western North Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions formed in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones (including tropical depressions) that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.

Seasonal forecasts

On January 4, Dr. Prisco Nilo, the director of PAGASA, reported that PAGASA were expecting 19 tropical cyclones or less during the typhoon season. PAGASA then reported on June 15, that the bulk of the activity would be coming up during the next three months with seven to ten tropical cyclones predicted to move through their area of responsibility. During May 2009, the Vietnamise National Centre for Hydro Meteorological forecasts predicted that the number of tropical cyclones causing damage to Vietnam during the season would be more than the average of six cyclones. On June 30 as Taiwan, entered their typhoon season, the Central Weather Bureau predicted that 24 to 27 tropical storms would form over the Western Pacific, with 3 or 5 tropical storms affecting Taiwan.

Since the 2000 season, the Laboratory for Atmospheric Research at the City University of Hong Kong has forecast the expected number of tropical cyclones, named storms, and typhoons in a season with forecasts released in April and June. This season, the CityUHK is predicting an about average season. An average season, according to the CityUHK, has 31 tropical cyclones, 27 named storms, and 17 typhoons. In its April forecast, the CityUHK predicted 31 total tropical cyclones, 27 named storms, and 18 typhoons. It also forecast that 4 tropical cyclones would make landfall in Southern China, all of which are expected to be in the early season (between May and August). A normal season sees 5 such landfalls, of which 3 are early and two are late (September to December). In its June forecast, the CityUHK lowered its prediction of how many tropical depressions would form this season to 30 whilst leaving their predictions of how many tropical depressions would intensify further the same as their April forecast. They also reported that due to a developing elnino event that only three systems were expected to make landfall on China between July and December.

Storms

Tropical Depression Auring

Tropical depression (JMA)
Duration	January 3 – January 6
Peak intensity	55 km/h (35 mph) (10-min); 1000 hPa (mbar)

On December 30 2008, an area of convection formed to the southeast of Manila, Philippines. Early on January 3, as the disturbance moved towards the west, the JMA designated the disturbance as a tropical depression. Later that morning PAGASA designated the depression as Auring. Later that day, the JTWC upgraded the potential of Auring becoming a significant tropical cyclone within 24 hours to fair. Late on January 5, PAGASA downgraded Auring to a Low Pressure Area. Late on January 7, the remnants of Tropical Depression Auring associated with an area of cloudiness brought scattered rainshowers across Eastern Luzon, Bicol Region, and Visayas, then dissipated.

The depression produced heavy rainfall and flooding on Mindanao in the Philippines, forcing 38,764 people to evacuate to shelters from their homes. The flooding destroyed 294 houses, killed two people, and left nine others missing. About 12,211 people were left stranded at ports due to dangerous conditions caused by the depression. An additional 14 trucks, 44 light cars, 75 passenger buses, 27 vessels and 295 rolling cargoes were also stranded. A total of 305 homes were destroyed and another 610 were damaged. In addition, an estimated 53 hectares (130.9 acres) of rice and 3.5 hectares (8.6 acres) of corn were damaged. About 43,851 people were affected by the depression and damages from the depression were estimated at PHP 23 million ($498,318 USD).

PAGASA Tropical Depression Bising

Tropical depression (PAGASA)
Duration	February 12 – February 14
Peak intensity	45 km/h (30 mph) (10-min); 1000 hPa (mbar)

On February 9, an area of disturbed weather formed 150 km (90 miles) to the north of the Republic of Palau. At this time satellite imagery had shown deep convection within an area of moderate vertical wind shear developing along the northern edge of a low level trough of low pressure. The next day, the JTWC reported that the disturbance had dissipated, but it regenerated early on February 12 and was designated as Tropical Depression Bising by PAGASA with peak winds of 45 km/h (30 mph). At this time PAGASA issued Public Warning Signal Number one, for parts of Visayas and Mindanao. Early the next day, PAGASA reported that Bising had made landfall on Dinagat Island, with winds of 45 km/h (30 mph); later that day, PAGASA cancelled all the Public Warning Signals for the Philippines and downgraded Bising to an area of low pressure. An estimated 473 passengers and several vehicles were stranded in Liloan and Ormoc due to ferry cancellations. In Cebu, an estimated 1,600 passengers were also stranded due to the depression. Late on February 14, the remnants of Tropical Depression Bising brought scattered rainshowers across Southern Luzon, Bicol Region, and Visayas, then dissipated. The rainfall led to mudslides on Cebu Island which blocked the Cebu Transcentral Highway.

PAGASA Tropical Depression Crising

Tropical depression (PAGASA)
Duration	April 30 – May 2
Peak intensity	55 km/h (35 mph) (10-min); 1000 hPa (mbar)

Early on April 29, the JTWC reported that an area of disturbed weather had formed about 430 km to the southwest of Manila in the Philippines. Satellite imagery showed an elongated low level circulation center with broken convective banding wrapping the southern edge of the disturbance, located within an area of low vertical wind shear. During the day the disturbance gradually consolidated and started to intensify under the influence of an anticyclone. As a result of this, a Tropical Cyclone Formation Alert (TCFA) was released by the JTWC later that day. Early the next morning PAGASA designated the disturbance as Tropical Depression Crising, and reported that Crising had peak windspeeds of 55 km/h (35 mph). Later that morning PAGASA put parts of Western Luzon under public storm warning signal number one whilst the depression was moving slowly towards the west within the South China Sea. Later that day the JTWC cancelled the TCFA on Crising as the low level circulation center was now poorly defined after it had interacted with another tropical disturbance that later became Tropical Storm 01W. However PAGASA kept issuing advisories on Crising and then early on May 1 PAGASA cancelled all the Public warning signals which were in place for western parts of Luzon. Early the next day, PAGASA reported that the tropical depression had weakened into a low pressure area and the final advisory was issued.

Heavy rains produced by the outer bands of Crising caused flooding in western areas of the Philippines, affecting an estimated 2,500 people. The worst flooding occurred in Lucena City where ten villages were isolated. Areas along the Bucon and Inalmasinan Rivers were inundated and sustained significant crop losses. Several animals reportedly drowned in the region. Several roads were impassable due to landslides or were washed out by floodwaters. One bridge was destroyed in the town of Mercedes.

Typhoon Kujira (Dante)

Very strong typhoon (JMA)
Category 4 typhoon (SSHWS)
Duration	May 1 – May 7
Peak intensity	155 km/h (100 mph) (10-min); 940 hPa (mbar)

Early on April 26, an area of disturbed weather formed near the coastline of Baler, capital of the Philippine's Aurora provence. It was formerly a tail end of cold front that passed by Northern Luzon. JTWC assesed that the area of a disturbed weather potential of becoming developing into a significant Tropical Cyclone within 24 hours as "fair". However, on April 28, JTWC downgraded the disturbance as dissipating because of interaction with nearby middle Tropical Depression Crising and JMA Tropical Depression 03. A few days later, the disturbance moved south-westward, and late on April 30, the disturbance made landfall at Albay. On May 1, JTWC again upgraded the disturbance into having a potential to form into a significant Tropical Cyclone within 24 hours to "fair". And later that day, PAGASA classified the disturbance as a tropical depression, naming it "Dante" and issued public storm warning signal number one in the provinces of Camarines Norte, Camarines Sur, Albay, Sorsogon, Catanduanes, Masbate, Burias Island, and Southern Quezon. PAGASA also reported that Dante made landfall in the vicinity of Sorsogon within the Bicol region of the Philippines. Early on May 2, JTWC issued a TCFA as the depression was in an almost stationary position. Later that day, JMA classified Dante as a full depression. Early the next morning it became a tropical storm and was named Kujira. Kujira continued to strengthen and was upgraded to a severe tropical storm that afternoon. When it was over the Philippines it killed 27 people while 9 others are missing. The JMA upgraded the system to a typhoon early on May 4. Kujira intensified quickly, doubling in strength from a Category 2 typhoon to a Category 4-equivalent typhoon within 24 hours. On May 6, The JTWC reported that Kujira was in its beginning stages of becoming extratropical, with the low level circulation center almost fully exposed in association with increasing vertical wind shear and lower sea surface temperatures in the region. Late that, JMA downgraded Kujira to a Severe Tropical Storm as strong wind shear weakens the system. Then early on May 7, JTWC issued its last advisory on Kujira, already reporting it as an extratropical system. JMA continued to issue warnings on the system while at the same time it was downgraded to a tropical storm. Later on May 7, Kujira weakened further, becoming a fully extratropical cyclone.

While in the Philippine area of responsibility, Kujira caused some 625,709,464 worth of damage to crops and livestock in Albay, Camarines Norte, Masbate and Sorsogon. It also caused some 102 million pesos worth of damage to communal irrigation systems in the region. The NDCC update as of 6AM PST May 12 declared 28 dead, one missing and 5 injured. Further, 383,457 persons in 609 barangays of 60 municipalities and 4 cities in 5 provinces of Region V were affected by the storm. Damages are worth PhP 1,228,422,344 million or PhP1.228 billion of which PhP 625,709,464 are agricultural losses and PhP 529.525 million in infrastructural. Houses destroyed were at 2387, of which 138 were total and 2249 partial.

Tropical Depression

Tropical depression (JMA)
Duration	May 1 – May 4
Peak intensity	55 km/h (35 mph) (10-min); 1004 hPa (mbar)

Late on April 28, the JTWC reported that an area of disturbed weather had persisted in an area of low vertical windshear to the southeast of Yap. Deep convection was wrapping into a poorly orgainzed but consolidating low level circulation center. However over the next few days its low level circulation center weakened with convection becoming very shallow and disorganised before it was declared as a Tropical depression on May 1 by the JMA. The JTWC then released a Tropical Cyclone Formation Alert early the next day as the low level circulation center had become well defined and convection increased with sea surface temperatures also becoming favourable for development. However the alert was cancelled later that day after the depression had peaked at 55 km/h (35 mph), as the low level circulation center had started to move under the upper level jet located to the north of the depression which had caused the vertical windshear over the system to increase. As a result of this the low level circualtion center began to detach from the convection and was loosing its tropical characteristics and was predicted to become a very strong extratropical low. However the JMA continued to issue advisories on the depression until early on May 4, when they downgraded it to an extratropical low.

Typhoon Chan-hom (Emong)

Typhoon (JMA)
Category 2 typhoon (SSHWS)
Duration	May 1 – May 13
Peak intensity	120 km/h (75 mph) (10-min); 975 hPa (mbar)

On May 1, an area of convectional cloudiness associated with an area of disturbed weather formed southeast of Nha Trang, Vietnam and associated with a remnant of Tropical depression Crising to form a new stronger area of disturbed weather system. JTWC monitored the disturbance as "Fair" for developing due to low vertical wind shear and an upper level anticyclone to the east of the system. Later on the JMA designated the low pressure as a minor tropical depression reporting the outlook track as southwestward. The JTWC issued a TCFA on the system once the convection increased and became better organized although with an exposed LLC east of its convection. Early morning of May 3, the JMA begun issuing tropical cyclone advisories on the system forecasting it to become a tropical storm later in the afternoon as it tracked eastwards. On May 3, the JTWC designated the disturbance as Tropical Depression 02W, and the JMA named the storm Chan-hom. Later on May 4, Chan-hom strengthened into a severe tropical storm. On May 6, the system moved into the Philippine Area of Responsibility from the west and was named as Emong. Later that day the JMA upgraded the severe tropical storm to a typhoon. On May 7, PAGASA reported that Chan-hom had made landfall at the northern tip of Bolinao, Pangasinan. After traversing Pangasinan it lashed La Union, Ilocos Sur, Benguet, Nueva Vizcaya, Ifugao, Mt. Province, Kalinga and Isabela. Pangasinan (which recorded 150mm of rain from Emong) and La Union were the worst hit. The provinces in Central Luzon, Ilocos, Cordillera Administrative Region and Cagayan Valley, together with Metro Manila and parts of Southern Luzon, generally experienced more than 100 mm in the 24 hour period on May 7. Rains, however, lasted from May 6-8. NDCC updates on 6:00AM on May 13 put dead at 50, injured at 47 and missing at 13 and damage worth 690 million pesos in agriculture, infrastructure and private property. It further left 204,000 persons affected, damaged 23280 houses of which 6080 are totally damaged and 17200 partially damaged in Pangasinan and induced 11 landslide occurrences in Zambales and Cagayan PAGASA expected the typhoon to weaken quickly, which it did. On May 8, Chan-hom was downgraded to a Tropical Storm and later, to a Tropical Depression. JMA issued its last warning early on May 9, followed by the JTWC. PAGASA held on to Emong (Chan-hom) until much later that day, when it was declared an area of low pressure. JTWC then re-issued advisories on the restrengthening depression on May 10. Later on May 11, Chan-hom became a subtropical depression, therefore, JMA and PAGASA designated it a tropical depression while JTWC declared it dissipated , PAGASA reported Tropical Depression Chan-hom degenerated into Subtropical Disturbance ex-Chan-hom and issued the final advisory for the system because it had almost completely dissipated. However, JMA did not issue the final advisory for the tropical depression until early on May 13, when then circulation dissipated and it began accelerate northeastward in association of the jet stream and it was forecast to become extratropical or be absorbed by a cold front.

Severe Tropical Storm Linfa

Severe tropical storm (JMA)
Category 1 typhoon (SSHWS)
Duration	June 14 – June 23
Peak intensity	110 km/h (70 mph) (10-min); 975 hPa (mbar)

On June 10, the JTWC began monitoring an area of disturbed weather that was situated about 140 kilometres (85 mi) southeast of Palau. Satellite imagery depicted an elongated low-level circulation, with deep convection centered along the southwestern portion of the system. Over the next couple of days, the disturbance gradually developed with the JMA declaring the system as a tropical depression early on June 14 whilst the JTWC issued a TCFA. However the TCFA was later cancelled due to the convection dissipating, whilst the JMA downgraded the depression to an area of low pressure. Over the next two days, the system moved across Luzon and began to regenerate. Early on June 17, a second TCFA was released by the JTWC whilst the JMA reported that the system had reintensifed into a tropical depression. Later that day, the JTWC designated the system as Tropical Depression 03W whilst the storm was situated about 705 km (440 mi) south-southwest of Kaohsiung, Taiwan.

Following further development of the depression, the JTWC upgraded it to a tropical storm late on June 17. The JMA then followed suit early the next morning assigning the name Linfa to the storm. Throughout the rest of the day limited poleward outflow prevented linfa from intensifying. During June 19, Linfa intensified further and became a severe tropical storm with an eye feature starting to appear on microwave imagery. After interacting with a nearby upper-level low, outflow significantly improved later that day, fueling further strengthening, before the next day the JTWC upgraded Linfa to a typhoon as it reached its peak windspeeds of 140 km/h (85 mph) 110 km/h (70 mph 10-minute winds). Later that day convection near the center of the circulation to decrease with the eye no longer visible. Upper-level wind shear rapidly increased, preventing re-intensification of the cyclone. Linfa then began to interact with land and was downgraded to a tropical storm by the JTWC on June 21 and then during that afternoon the storm made landfall on the southern Chinese provence of Fujian. Deep convection then rapidly dissipated with both the JMA and the JTWC downgrading Linfa to a Tropical depression by early on July 22, as the storm moved away from the Chinese coastline. The system later dissipated just offshore with a circulation was no longer evident on satellite imagery.

A total of seven people were killed by Linfa, whilst (2009 US)$110 million worth of damage was done by Linfa, as it affected China, Taiwan, Hong Kong and the Philippines. A 498-tonne oil tanker was run aground in southern Taiwan by large swells of up to 5.6 m (18 ft). In Taiwan two people were hit by fallen trees, whilst power cuts were reported in Chiangchun as well as other parts of China and Taiwan. A total loss of NT$400 million (US$12.1 million) was suffered by the agricultural sector in Taiwan whilst in mainland China, Linfa produced torrential rainfall which led to severe flooding. Following a landslide, one person was killed. Flood waters destroyed 100 homes and inundated 10,000 others as well as an estimated 32,000 hectares of farmland in Fujian Province. In Meizhou, Guongdong Province, flash flooding resulted in five additional fatalities after 413.7 mm 19.22 in of rain fell within a nine-hour span. A total of 362 homes were destroyed in the town and infrastructure was severely damaged. Additionally, an estimated 20 million people were affected by the storm.

Tropical Storm Nangka (Feria)

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	June 22 – June 26
Peak intensity	75 km/h (45 mph) (10-min); 994 hPa (mbar)

On June 16, an area of disturbed weather formed about 170 km (120 miles) to the northeast of Palau Island. In the next few days, the disturbance showed improvement but, its LLCC was undefined. Early on June 20, the disturbance suddenly strengthened and its LLCC began to consolidate as well as significant banding all over the system. The disturbance was also located under low vertical wind shear. Early on June 22, JTWC issued an advisory that the potential of the formation of a significant tropical cyclone within 24 hours was upgraded to "Fair" because of its well-defined LLCC and was located in a favorable area. Around 0600 UTC that same day, the JMA classified the disturbance as a minor Tropical Depression, while the JTWC released a TCFA on the disturbance. This was because convection had begun to organize and upper-level analysis showed a cyclonic center on the east, just west of Guam and a cyclonic flow around its consolidating low level circulation Centre. After 4 hours, JTWC issued its first warning and named it as Tropical Depression 04W. Early on June 23, PAGASA issued its first warning on the Tropical Depression and assigned its local named "Feria". In the afternoon, Nangka made its first landfall over Hernani, Eastern Samar at 5:00 pm PST (0900 UTC). and made its second landfall in Masbate around 10:00PM PST ( 1400 UTC). On June 24, Nangka rapidly slowed down while moving over Mindoro. The storm then made its third landfall at Calapan City, Mindoro at 12 am PST/ 0430 UTC. After crossing Mindoro for 8 hours, PAGASA downgraded Nangka into a Tropical Depression, while both the JMA and JTWC still classified Nangka as a tropical storm on that day. Early on June 25, Nangka move into the South China Sea, with PAGASA issuing their final warning. In the evening of that same day, both JMA and JTWC downgraded Nangka into a tropical depression due to its low level circulation center is started to deteriorate. By midday of June 26, it made its forth landfall in the Guangzhou province in China, passing through the northern part of Hong Kong. In the afternoon of that day, both JMA and JTWC issued their final warning on Nangka. Its remnants completely dissipated by June 27.

In Eastern Samar, more than 800 people were stranded after ferry service was canceled. High winds downed a large tree, destroying the roof of one home and damaging three cars. Unusually strong severe thunderstorms developed over parts of the Philippines along the outer bands of Nangka. In San Pascual, Bauan and Batangas City, large hail fell during a strong storm. Residents reported that they have never seen hail before. In Barangay, 4 in Bauan town, a rare tornado struck, downing several trees, damaging homes and signs. Heavy rains produced by the storm also flooded numerous regions, some reporting waist-deep water. Later reports confirmed the tornado destroyed 23 homes. In Cebu, one person was killed and seven were left missing. At least 500 people were also left homeless due to the storm. In Cavite,7000 was stranded on the port due to Nangka's winds and heavy rains. about 4 feet is the water wave in Cavite. In Albay, more than 300 ship passengers were also stranded at the Albay port, Tabaco, Albay. In Navotas and Malabon, the Navotas - Malabon river produced a 3 foot high tide in the area.

As of 24 June, Nangka (Feria) has caused 6 deaths and left 11 people missing. Property damage from the storm is estimated at PHP 2.8 million (US$54,000).

Tropical Storm Soudelor (Gorio)

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	July 9 – July 13
Peak intensity	65 km/h (40 mph) (10-min); 992 hPa (mbar)

Late on July 7, the JTWC reported that an area of disturbed weather had formed about 900 km (560 mi) to the northwest of Yap. Deep convection was embedded in a broad, weak, poorly defined circulation that was starting to be enhanced by a Tropical Upper Tropospheric Trough (TUTT) cell to the east of the system. Over the next couple of days, gradual development took place before a TCFA was released by the JTWC early on July 9 as PAGASA designated the system as Tropical Depression Gorio. Later that day both the JMA and the JTWC reported that the depression had formed and started to issue warnings on the depression, with the JTWC designating it as 05W. On July 10, PAGASA issued their final advisory on Tropical Depression Gorio as it moved out of their area of responsibility. Hampered by an unfavorable upper-level environment, the depression barely intensified into a tropical storm early on July 11. Upon becoming a tropical storm, the JMA named the system Soudelor reporting peak winds of 65 km/h, (40 mph). Later that day the JTWC reported that Soudelor had weakened into a depression; however they re-upgraded it to a tropical storm as it moved closer to Hainan Province. Shortly before landfall in Leizhou Peninsula, China, the JTWC downgraded the storm to a tropical depression, then as Soudelor moved back over water and into the Gulf of Tonkin, the JTWC issued their final advisory on the depression, however the JMA continued to monitor the storm until it had made landfall near Fangchenggang, China several hours later.

As a tropical depression, Soudelor brushed northern Luzon in the Philippines, producing upwards of 330 mm (13 in) of rainfall which resulted in flash flooding and landslides in at least ten villages. In China torrential rains in Hainan caused significant flooding that killed 15 hikers and left several others missing. Numerous roads were also cut off or destroyed by landslides and 30 villages were inundated with flood waters. The remnants of Soudelor produced widespread torrential rains in Northern Vietnam on July 13. Rainfall totals peaked at 250 mm (9.8 in) in the region. Heavy rainfall, amounting to 130 mm (5.1 in), was also recorded in Hanoi. The capital city experienced flash flooding, inundating numerous streets and buildings. Two men were killed by lightning strikes associated with the storm. Officials reported that at least 13 large trees had been downed by high winds. Flood waters in the hardest-hit areas reached a depth of 0.35 m (1.1 ft). One person was killed after being swept away. A tornado also touched down during the storm, destroying the roofs of three homes. Thousands of hectares of croplands were inundated by flood waters. Following the storm, 1,000 tonnes of rice was allocated for victims of the floods.

Tropical Depression Huaning

Tropical depression (JMA)
Tropical depression (SSHWS)
Duration	July 11 – July 14
Peak intensity	55 km/h (35 mph) (10-min); 1000 hPa (mbar)

On July 10, the JTWC reported that an area of disturbed weather had persisted about 1065 km (660 mi) to the east of Manila. The convection was consolidating with a good mid level circulation and was located under a anticyclone and had started to show some outflow into a trough to the northeast of the system. Early the next day the JMA reported that the disturbance had become a minor tropical depression. The depression then gradually developed during the rest of July 11, with PAGASA naming the depression as Huaning early on July 12 whilst the JTWC issued a Tropical Cyclone Formation Alert on the depression. Early the next day PAGASA upgraded Huaning into tropical storm whilst the JTWC designated the depression as Tropical Depression 06W. Later that morning Huaning made its first landfall over Chungyang, Taiwan. On the next day, both JMA and JTWC issued their final warning on Huaning.

Typhoon Molave (Isang)

Typhoon (JMA)
Category 1 typhoon (SSHWS)
Duration	July 14 – July 19
Peak intensity	120 km/h (75 mph) (10-min); 975 hPa (mbar)

Late on July 10, an area of disturbed weather persisted about 280 km (175 miles), to the southeast of Yap. Convection was wrapping into a poorly organized and drawn out low level circulation center and was under minimal wind shear. It gradually developed further throughout the next day with convection continuing to consolidate over a low level circulation center. However early on July 12, the JTWC reported that the disturbance had dissipated, as outflow was being hampered by the outflow of Huaning. However late on July 13, the JTWC reported that the disturbance had rapidly redeveloped and released a TCFA on the disturbance. Early the next day both PAGASA and the JMA designated the disturbance as a Tropical Depression with PAGASA assigning the local name of Isang to the depression. The Depression continued to develop and was designated as Tropical Depression 07W by the JTWC early on July 15, whilst PAGASA upgraded Isang to a Tropical storm later that day. On July 17, JMA upgraded Molave as a Severe Tropical Storm and Typhoon by PAGASA. On morning of July 18, HKO upgraded Molave as a Typhoon. Later that day, Molave quickly moved into the South China Sea. On July 19, at 1700 UTC or 1am HKT, Molave made its first landfall. On the afternoon, as Molave move through China, both JMA and JTWC issued their final warning as Molave weakened into a Tropical depression. Molave killed at least four people.

Tropical Storm Goni (Jolina)

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	July 30 – August 9
Peak intensity	75 km/h (45 mph) (10-min); 988 hPa (mbar)

Late on July 25, the JTWC reported that an area of convection had formed in a monsoon trough about 815 km (515 mi) to the northeast of Guam. Deep convection was flaring around the low level circulation center. An upper level anticyclone and a tropical upper tropospheric trough was providing outflow. Over the next few days the disturbance gradually developed before the disturbance was declared as dissipated early on July 28 as the low level circulation center was not well defined and higher vertical wind shear affecting the system. However the disturbance regenerated early on July 30 whilst located about 630 km (390 mi), the disturbance's low level circualtion center was elongated with indications of multiple circulation centers. Later that day PAGASA reported that the disturbance had developed into a tropical depression and assigned its local name of Jolina. Jolina then intensifed further early the next day and was reported to have become a tropical storm by PAGASA, with the JMA designating it as a depression later that day. Early on August 1 the JTWC issued a Tropical Cyclone Formation Alert as deep convection had increased and was starting to consolidate around a circulation center. However later that morning Jolina made a landfall near to Casiguran, in the Philippine province of Aurora before emerging out in to the South China sea later that day. Early the next day the JTWC reissued their TCFA whilst PAGASA issued their final warning on Jolina as it moved out of their area of responsibility heading towards a landfall on China. The JTWC then designated the depression as 08W later that day as infrared imagery had shown deep convection was wrapping into the low level circulation center. During August 3, the JMA reported that the tropical depression had intensified into a tropical storm and assigned the Goni to the cyclone. At 1700 UTC of August 4, Goni made its second landfall over Macau. Early on the next day, JTWC issued their final warning on Goni. On August 7, The Joint Typhoon Warning noted that remnant of Goni re-entered into the Gulf of Tonkin and had a poor chance of regenerating. Later in the day, Joint Typhoon Warning Center reissued advisories on the system upgrading it to a tropical storm near Hainan Island.

In the Philippines Goni (Jolina) death toll is 8 with 5 more missing. Goni (Jolina) affected 38,589 families or 160,038 people in 119 villages in 25 towns and five cities in Ilocos Sur, Batangas, Cagayan, Nueva Ecija, Rizal, Mindoro Occidental, Palawan, Iloilo, Negros Occidental, Lanao del Sur, and Sultan Kudarat town in Maguindanao. Five people died in China when Goni passed through. In Hainan province about 92,000 people had been evacuated by the authories. 575 houses got destroyed and 2,311 damaged. The storm also inundated than 68,000 hectars cropland.

Typhoon Morakot (Kiko)

Typhoon (JMA)
Category 2 typhoon (SSHWS)
Duration	August 2 – August 11
Peak intensity	150 km/h (90 mph) (10-min); 945 hPa (mbar)

Early on August 2, the JMA reported that the season's eleventh tropical depression had formed within a monsoon trough about 1000 km (620 miles) east of the Philippines. The depression remained weak, however, and later that day the JMA downgraded it to an area of convection. Still later that day, the JMA reported that the tropical depression had regenerated and that deep convection was flaring on the western side of a partially exposed low level circulation center. On August 3, PAGASA named the depression Kiko as it moved through their area of responsibility, after which (the same day) the JMA named the storm Morakot, upgrading it to a Tropical Storm. The JTWC followed suit, designating Morakot as 09W. The next day Morakot recurved, reentering PAGASA's area of responsibility.

In the Philippines, ten villages (Paudpod, San Juan, Batonloc, Carael, Tampo, Paco, San Miguel, Bining, Bangan, and Capayawan) have been submerged in 4-foot to 5-foot deep floods after the Pinatubo Dike overflowed. Joint military and police rescue teams rescued 3 Koreans and 9 Canadian nationals. About 30,000 families were affected by Morakot; eleven people are confirmed dead. Three French tourists and two Filipino guides were killed in a flashflood caused by a landslide. Thousands are trapped on rooftops or in trees awaiting helicopter rescue attempts and thousands have lost their homes. At least two have died from flooding. Landslides have claimed the lives of two children and five miners are still missing after a landslide destroyed their huts. Schools have suspended their classes in the hardest hit area, and highways have been closed due to landslides.

In Taiwan, where schools were closed ahead of the typhoon, Morakot caused landslides, severe floods, blew down trees and billboards, and stripped roofs from buildings. In a positive impact, Morakot brought much-needed rain to Taiwan, ending a months-long drought, and replenished reservoirs enough to warrant an end to water rationing. On that island, two people were killed with four missing. Almost the entire southern Taiwan (Chiayi, Tainan, Kaohsuing, and Pingtung) are flooded by record-breaking heavy rain. It is estimated that rainfall in Pingtung county may reach as much as 2,500 millimeters, breaking all rainfall records of any single place in Taiwan induced by a single typhoon.

South east China has evacuated 20,000 residents. A fishing boat has capsized and search and rescue efforts have begun for nine missing fishermen. A total of 34000 watercraft sought refuge ahead of the storm.

On August 13, the remnants of Tropical Storm Maka crossed the international dateline and moved into the Western Pacific; where it was immediately designated as a tropical depression by the JMA. Later that day the JTWC reported that the depression was located about 1425 km (885 miles) to the southeast of Wake Island, with deep convection developing over the northern quadrant of a stretched out, low level circulation center which was in an area of low to moderate vertical wind shear and had a good outflow into an upper level trough. During the next day, the JTWC issued a Tropical Cyclone Formation Alert on the depression as the low level circulation center had developed further. Later that day, the JTWC re-upgraded the disturbance to Tropical Depression 01C (Maka). Late the next day the JTWC upgraded the depression to a tropical storm however, the JMA still classified the storm as a depression.

On August 14, an area of convectional cloudiness associated with a monsoon formed about (400 miles) 750 km to the northeast of Pohnpei. Satellite imagery began showing that convective bands were starting to wrap into the Low Level Circulation Center (LLCC) from the northeast to southwest and the system was also under an area of low shear with some poleward outflow into a Tropical Upper Tropospheric Trough (TUTT) that was located to the northeast. The next day, the system was showing more good outflow and its LLCC was now fully exposed, whilst the JMA upgraded the system into a tropical depression in the afternoon of August 16. Early of the next day, JTWC issued a TCFA as the system developed rapidly. On August 17, the JMA upgraded the system to Tropical Storm Vamco while JTWC classified it as tropical depression 11W. On the next day, JTWC finally upgraded TD 11W into a tropical storm. Several hours later, the JMA reported that Vamco had strengthened into a severe tropical storm. Early of August 19, the JMA reported that Vamco had intensified to a minimal typhoon. After 06 hours, a small eye feature was appeared in satellite imagery, whilst Vamco was upgraded into a Category 2 equivalent . Early on August 22, Vamco reached its peak intensity as a Category 4 equivalent. Around August 25, Vamco was nearing the southwesternmost Aleutian Islands, and was quickly losing tropical characteristics, as it was becoming more frontal in nature, as well as portions of the eye were quickly eroding. Around the same time, the JTWC issued their final advisory on Vamco. A few hours later, the JMA also issued their final advisory on the weakening storm.

Early on August 25, the JTWC reported that an area of convection had persisted about 1000 km (630 mi) to the southeast of Okinawa, Japan. The convection was moving over a broad and ill defined low level circulation center, it was also located in an area of low vertical wind shear. An upper level trough was approaching the system from the northwest and was hindering outflow, bringing cooler and drier air to the disturbance. Later that day the JMA then designated the disturbance as the sixteenth tropical depression of the season, before early the next morning the JTWC reported that the depression had dissipated. However the JMA continued to issue advisories on the depression, until later that day when the JMA issued their final warning on the depression.

On August 27, JMA reported that an area of convectional cloudiness associated with monsoon through formed about 720 km (450 mi), to the southeast of Iwo To, Japan. Satellite imagery shows that convective bands is starting to wrap into the Low Level Circulation Centre (LLCC) and the system is located in moderate vertical windshear and favorable area. Early of August 28, the system is showing a good development LLCC then the JMA upgraded the system into a minor tropical depression. While JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the system then after several hours, they upgraded it into a tropical depression. In the evening of that day, the depression rapidly intensified into a tropical storm due to hot water temperatures and associated with Tropical Upper Tropospheric Trough (TUTT) that located in the northeast of the tropical storm, whilst JMA assigned the name Krovanh. While JTWC also upgraded the depression into a tropical storm. Early of August 30, JMA upgraded Krovanh into a severe tropical storm. On the next day, Krovanh weakened into a tropical storm due to its interaction with the frontal system and the eye was quickly become visible. On September 1, both JMA and JTWC issued their final warning on Krovanh. The remnants of the storm was absorbed by a frontal system and dissipated later that day.

Tropical Depression

Tropical depression (JMA)
Tropical depression (SSHWS)
Duration	August 29 – September 1
Peak intensity	55 km/h (35 mph) (10-min); 1004 hPa (mbar)

Late on August 29, the JMA started to issue warnings on Tropical Depression 02C as it was expected to cross the International Dateline and move into the Western Pacific within 24 hours and intensify into a Tropical Storm. Early the next day the depression crossed the dateline into an area of strong vertical windshear. Thus the tropical depression began to weaken with the low level circulation center becoming fully exposed and sheared as a result the JTWC issued their final advisory later that day. However the JMA continued to issue advisories on the depression until early on September 2, they downgraded the depression to an area of low pressure and issued their final advisory.

Severe Tropical Storm Dujuan (Labuyo)

Severe tropical storm (JMA)
Tropical storm (SSHWS)
Duration	September 1 – September 10
Peak intensity	95 km/h (60 mph) (10-min); 980 hPa (mbar)

On August 28, an area of convectional cloudiness associated with monsoon through formed about (620 miles) 1000 km southwest of Okinawa, Japan. Satellite imagery revealed that a partial Low Level Circulation Centre was exposed with an anticyclone was providing good outflow that located to the northwest of the system. Early of September 1, the system showed a more defined LLCC and moving through warm waters, whilst JMA upgraded the system to a tropical depression. On September 2, the depression entered in the Philippine area of responsibility and PAGASA assigned it a local name Labuyo. On the next day, PAGASA upgraded Labuyo into a tropical storm while JTWC issued a TCFA. Later that day, JTWC designated it is tropical depression 13W. Early next day, JMA upgraded the depression intensified into a tropical storm and assigned it a international name Dujuan, while JTWC then also upgraded Dujuan as a tropical storm. On September 5, JMA upgraded Dujuan into a severe tropical storm. Later that day, PAGASA issued their final warning on Labuyo as the storm moved out on their area of responsibility. Early of September 8, JTWC downgraded Dujuan into a tropical depression. After several hours of that same day, JTWC amended a issue that Dujuan was intensified again into a tropical storm.

Tropical Depression

Tropical depression (JMA)
Duration	September 3 – September 9
Peak intensity	45 km/h (30 mph) (10-min); 1000 hPa (mbar)

Early on September 1, the JTWC reported that an area of convectional cloudiness had persisted in an area of low pressure vertical windshear about 500 km (305 mi) to the northwest of Manila in the Philippines. The system had a fully exposed low level circulation center with small pockets of convection confined to the western edge of the cyclone. During the next couple of days the disturbance developed further with deep convection consolidating near the low level circulation center before being designated as a tropical depression by the JMA and had a Tropical Cyclone Formation Alert issued by the JTWC early on September 3. Later the next day, it made a direct hit on Đà Nẵng, Quảng Nam and Quảng Ngãi, Vietnam and after several hours. Later that day, JTWC had cancelled TCFA. It had re-emerged back into the South China Sea and remained nearly stationary.

At least six people have been killed and five others were injured by the depression throughout Vietnam. Rainfall from the storm exceeded 430 mm (17 in), triggering widespread flash flooding. Sixty-one tons of fish were swept away during the floods and 8,700 hectares of rice were destroyed.

Tropical Storm Mujigae (Maring)

Tropical storm (JMA)
Tropical depression (SSHWS)
Duration	September 8 – September 12
Peak intensity	65 km/h (40 mph) (10-min); 994 hPa (mbar)

On September 6, an area of convection cloudiness associated with the monsoon through was formed about 305 km (200 mi) to the northwest of Manila, Philippines. Satellite imagery shows that a mid - level convection consolidating in over a developing Low Level Circulation Centre (LLCC). In additionally, there is a westerly wind burst that located three to five degrees of the system and located in moderate vertical wind shear. Late of September 8, the system is moving northwest and also in hot water temperatures, whilst the JMA upgraded the system into a tropical depression. Also, on the evening, PAGASA declared the system as a tropical depression and assigned its local name, Maring. While JTWC issued a Tropical Cyclone Formation Alert (TCFA). Early of the next day, JTWC upgraded the system into a tropical depression due to its LLCC is partially exposed. In the evening, as the depression is moving northwestward, PAGASA issued its final advisory as Maring moves out in their area of responsibility.

Typhoon Koppu (Nando)

Typhoon (JMA)
Category 1 typhoon (SSHWS)
Duration	September 11 – September 16
Peak intensity	120 km/h (75 mph) (10-min); 975 hPa (mbar)

On September 9, an area of convectional cloudiness associated with the monsoon trough formed 370 km (250 mi) to the northwest of Palau. Satellite imagery showed that a consolidating Low Level Circulation Centre (LLCC) with convection had started to develop and was wrapping toward the center. On September 11, the LLCC started to show improvement and was under moderate vertical shear with good westward outflow, but the JMA still upgraded the system to a minor tropical depression. Early of September 12, PAGASA upgraded the system in their responsibility and assigned its local name, Nando. At 1500 UTC, PAGASA reported that the depression made its landfall over northern Palanan, Isabela of the Philippines. However both JMA and JTWC reported that the depression didn't made its landfall but only crossed the Luzon straight. Early of the next day, JTWC upgraded the system into a tropical depression. Early of September 13, both JMA JTWC upgraded the system as a tropical storm and assigned its international name, Koppu. In the afternoon, JMA reported that Koppu intensified into a severe tropical storm. On the 14th, the JMA reported that Koppu had intensified to a minimal typhoon, but the JTWC still kept Koppu as a tropical storm for the next few hours but later acknowledging the intensification and upgraded Koppu to a minimal typhoon. But the JTWC issued their final advisory early on September 15, as Koppu was moving over land, and was expected to dissipate quickly.

In Luzon, a 48 hour rainfall was experienced. In Visayas and Mindanao, a 24 hour rainfall was also experienced due to Nando's enhancing southwest monsoon. About 10 provinces were raised in signal warning no.1 from September 12 - September 13. Nando had triggered landslides resulting road closures and evacuations of some residents in Kalinga province. The storm then caused major flood in Luoding, People's Republic of China.

Typhoon Choi-wan

Very strong typhoon (JMA)
Category 5 super typhoon (SSHWS)
Duration	September 12 – September 20
Peak intensity	185 km/h (115 mph) (10-min); 915 hPa (mbar)

Typhoon Choi-wan formed as weak tropical disturbance early on September 11, 2009, about 1100 kilometers (700 mi) to the east of Guam. During that day the disturbance rapidly developed and was designated as a tropical depression early the next day by both the JMA and the JTWC before intensifying further and being named as Tropical Storm Choi-wan on September 12. During September 13, Choi-wan's rapid intensification slowed down barely intensifying into a severe tropical storm, before early the next day it was upgraded to a typhoon and rapidly intensified during the day to become a Category 4-equivalent typhoon. Choi-wan then intensified further during September 15, as it moved through the Northern Marina Islands with the Japan Meteorological Agency reporting peak wind speeds of 185 km/h (115 mph), whilst the Joint Typhoon Warning Center reported 1-minute peak wind speeds of 260 km/h (160 mph) which made it a category 5-equivalent typhoon.

With the help of excellent poleward outflow and high ocean heat content, Choi-wan remained at its peak intensity until early on September 17 when deep convection started to erode in the northwestern quadrant as the tropical upper tropospheric trough cell to the northwest was no longer providing good outflow. Choi-wan was then downgraded to a typhoon by the JTWC as it started to undergo an eyewall replacement cycle, with the JTWC reporting a secondary peak intensity of 150 km/h, (90 mph), during the next day. During September 19, Choi-wan rapidly weakened, as it moved into an unfavorable environment with higher amounts of vertical wind shear, causing the storm's deep convection to erode. As a result of this and dry latitude air wrapping into the low level circulation center, the JTWC decided to downgrade Choi-wan to an extratropical system and released their final advisory early the next day, before the JMA followed suit later that day.

Despite the intensity of Choi-wan when it passed over the Northern Marina Islands, there was no casualties reported. It was determined afterwards by the US Navy that the whole island of Alamagan was uninhabitable, with all but one of the structures, a facility for laboratory and research, completely destroyed and most of the islands' trees downed. As a result it was determined that all of the residents of Alamagan and Agrihan needed to be completely evacuated to Saipan.

Tropical Depression

Tropical depression (JMA)
Duration	September 23 – September 26
Peak intensity	45 km/h (30 mph) (10-min); 1006 hPa (mbar)

Early on September 23, the JMA reported that a Tropical Depression had formed about 1145 km (710 miles) to the southeast of Tokyo, Japan. During that day the depression moved towards the northwest before the JTWC reported early the next morning that the depression was a vertically stacked upper level low with a closed circulation which was transitioning into a tropical system with a warm core. However as the system lacked any central convection and upper level conditions deteriorated as a longwave trough passed by the system it was reported as dissipated early on September 25 by the JTWC, however the JMA continued to monitor the system until early the next day before issuing their final advisory on the depression.

Typhoon Ketsana (Ondoy)

Typhoon (JMA)
Category 2 typhoon (SSHWS)
Duration	September 23 – September 30
Peak intensity	140 km/h (85 mph) (10-min); 960 hPa (mbar)

On September 22, an area of convectional cloudiness associated with the monsoon trough had formed about 720 km (450 mi), to the east of Manila, Philippines. Satellite imagery showed deep convection starting to consolidate about an LLCC. In the afternoon of the next day, the system started showing good outflow in LLCC and was moving through moderate vertical shear whilst the JMA upgraded the system to a tropical depression. On the evening of the same day, the JMA reported that the depression weakened into an area of low pressure. In the afternoon of September 24, the JMA reported that the system was organizing again and was upgraded to a tropical depression again, while the PAGASA also upgraded the system to a tropical depression and assigned it the local name Ondoy. On the same day, the JTWC also issued a TCFA on the system. Early the next day, the JTWC upgraded the system to a tropical depression again. In the evening, the PAGASA reported that Ondoy intensified into a tropical storm. Early on September 26, the JTWC upgraded the depression to a tropical storm as well. At the same time, JMA also upgraded it as a tropical storm and assigned it the international designated name Ketsana.

In the Philippines, the whole archipelago experienced a torrential rain starting on September 23. more than 30 areas in Luzon, including Metro Manila, were placed under storm alerts as tropical storm "Ondoy" accelerated further and moved closer to Central Luzon. On Bicol region, ferry passengers were suspended during September 25 through the next day due to high waves and heavy rains that were brought by Ketsana into the region affecting about 2000 people. In the Manila International Airport, 13 flights were cancelled due to Ketsana making landfall. Some universities in Manila suspended their classes due to severe flooding in some areas and heavy rainfall.

In addition, the PAGASA also advised residents living in low-lying areas and near mountain slopes in areas affected by the Southwest Monsoon and those under signals #1 and #2 (see below) are alerted against possible flashfloods and landslides. Also, PAGASA has alerted the National Disaster Coordinating Council (NDCC) for possible flashfloods and landslides in the affected areas, partcularly in Laguna, Quezon, Zambales, Pampanga and Bataan provinces. Philippine Coast Guard commandant Admiral Wilfredo Tamayo also reminded owners of seacraft of a guideline barring travel for seacraft weighing 1,000 tons or less.

A total of 25 provinces and Metro Manila were placed under state of calamity, with Metro Manila experiencing a record amount of rainfall in 42 years, with rain falling between 8:00 a.m. and 2:00 p.m. of September 26 pegged at 341mm, over the record established in June 1967 at 334mm.

Tropical Depression 18W

Tropical depression (JMA)
Tropical storm (SSHWS)
Duration	September 27 – September 30
Peak intensity	55 km/h (35 mph) (10-min); 1000 hPa (mbar)

The JTWC reported on September 24 that an area of convection had persisted about 725 km (450 mi) to the northeast of Pohnpei. Deep convection had started to conslidate and wrap around the low level circulation centre. By September 26, the system had developed strong outflow and was intensifying with the JMA reporting later that day that it had become a Tropical Depression however the JTWC did not follow suit until early the next day when they assigned the designation of 18W to the depression. During the next couple of days very little intensification took place as convection barely deepened around the low-level circulation center and in fact weakened due to the precursor system to Typhoon Parma was developing to the southeast of 18W. However early on September 29, the JTWC upgraded the depression to a tropical storm with peak windspeeds of 65 km/h (40 mph) whilst the JMA reported peak windspeeds of 55 km/h (35 mph). As 18W approached Guam, the system became severely disrupted after interaction with what were to become Typhoons Melor and Parma. As it passed near the island, the storm rapidly dissipated, first weakening to a depression and then as it lost its low-level circulation centre it was no longer considered a tropical cyclone and thus the final warnings from the JTWC and the JMA were issued.

Despite a state of emergency being declared by the Governor of Guam before the depression affected Guam on September 29, it had very little imapct on Guam. With only increased winds and moderate rainfall reported. All flights in and out of Guam were cancelled until the storm had passed. Five ships and a submarine from the United States Navy moved out to sea to avoid the storm; however, one submarine was unable to leave and remained at port during the storm.

Typhoon Parma (Pepeng)

Violent typhoon (JMA)
Category 4 super typhoon (SSHWS)
Duration	September 27 – October 14
Peak intensity	195 km/h (120 mph) (10-min); 920 hPa (mbar)

Early on September 25, an area of convectional cloudiness associated with the monsoon through formed 410 km (280 mi) to the southeast of Palau. Satellite imagery showed a consolidating Low Level Circulation Centre. On September 27, the system began improving and showing a partial LLCC due to favorable conditions and was also located under moderate vertical wind shear, whilst the JMA upgraded the system into a tropical depression. On the evening of that day, the JTWC issued a Tropical Cyclone Formation Alert. On the next day, JMA reported that the depression had intensified into a tropical storm, submitting its international designated name, Parma. Also, on the same day, JTWC upgraded it to a tropical depression. On the next day, JTWC again upgraded the depression into a tropical storm. And, by early September 30, due to the storm moving through warm water temperatures, the JTWC and JMA upgraded it to a Category 1 typhoon. Satellite imagery also began showing that an eye wall structure had formed. Intensification continued into in the morning of the next day, reaching Category 3 status. Then, after four hours, Parma rapidly strengthened to a Category 4 super typhoon, reaching its peak strength. Different weather bureaus forecasted that Parma would intensify into a Category 5 super typhoon, however, it weakened in the afternoon of October 1 as the eye of Parma began to degrade due to its movement into unfavorable conditions. Parma continued to slightly weaken while moving through the area of Cagayan, then by midday of October 3, it was downgraded into a Category 3-equivalent typhoon. Before it made landfall over northern Cagayan at 3:00 pm PST(07:00 UTC), it weakened into a Category 2 typhoon. Parma crossed northern Luzon over 12 hours, during which the typhoon weakened into a category 1 equivalent typhoon. PAGASA reported that the typhoon was moving almost stationary in their area of responsibility due to interaction with Typhoon Melor and a ridge of high pressure area over mainland China. At the same time, JTWC downgraded Parma into a tropical storm while the JMA downgraded it into a severe tropical storm. Early the next day, satellite imagery revealed that Parma had an eye center but no convectional cloudiness due to high pressure. Intensification was unlikely because of unfavorable environment conditions and interaction with Typhoon Melor. On October 7, Parma weakens into a tropical depression while it is crossing the northern Luzon and moving out into the Philippine area of responsibility, then PAGASA issued their final warning on Parma. On the next day, both JMA and JTWC reported that Parma re intensified into a tropical storm while it is on south China sea. Intensification is almost difficult due to moderate vertical wind shear. Then by late of October 12, it made it's fourth landfall over Hainan Island in China. Then, In early of October 14, Parma was downgraded by JMA to a tropical depression due lack of convection. Then by the afternoon of that day, it made it's forth landfall over the coastline of Vietnam. In the evening, JMA reported that Parma weakens into an area of low pressure, becoming the agency issues their final advisory. However, JTWC still considered Parma as a tropical storm.

On October 6, at 11:00 pm PST (15:00 UTC), Parma made its second landfall over Ilocos Norte. In the afternoon of the next day, PAGASA reported that Parma weakened into a tropical depression near the Isabela area, while both JMA and JTWC still classified Parma as a tropical storm. In the morning of October 8, it emerged back into waters near Isabela. After four hours, Parma made its third landfall in Cagayan. The next day, Parma crossed Northern Luzon for the second time. Then by the afternoon of that day, Parma exited La Union and emerged back into the South China Sea. At the same time, JTWC upgraded it into a tropical storm. On October 10, the JTWC downgraded it back to a tropical depression and once more upgraded it into a tropical storm. On October 12 it made landfall on the island of Hainan.

Typhoon Melor (Quedan)

Violent typhoon (JMA)
Category 5 super typhoon (SSHWS)
Duration	September 29 – October 9
Peak intensity	205 km/h (125 mph) (10-min); 910 hPa (mbar)

On September 28, an area of convectional cloudiness formed 370 km (250 mi) to the northeast of Pohnpei. Satellite imagery showed a Low Level Circulation Centre had begun to form. On the evening of September 28, due to a TUTT that was providing good outflow for the system and low level vertical wind shear with a favorable environment, the JTWC issued a Tropical Cyclone Formation Alert. Early on September 29, both JMA and JTWC upgraded the system into a tropical depression. Early on September 30, JMA reported that the depression had intensified into a tropical storm and assigned its international designated name, Melor. At the same time JTWC also classified the depression as a tropical storm. Early on October 1, Melor intensified further from a severe tropical storm into a typhoon. Intensification continued, and by the afternoon of the same day the JTWC reported that Melor had intensified into a Category 1-equivalent typhoon. In just four hours, it intensified rapidly to a Category 3-equivalent typhoon, and continued to track towards northeast Luzon. Early on October 2, it strengthened to a Category 4-equivalent typhoon. After levelling out in intensity, it strengthened again on October 3. Early October 4, JTWC reported that Melor had intensified to a Category-5 equivalent super typhoon, with JMA reporting a central pressure of 910 hPa and winds of 205 km/h. On October 5, PAGASA allocated the name Quedan to the typhoon as the storm moved into Philippine's area of responsibility. By the midday of October 8, Melor made landfall on Japan. After landfall, JMA downgraded Melor into a severe tropical storm, while the JTWC downgraded it into an extratropical storm. Late on October 9, the remains of Typhoon Melor were absorbed by a newly formed low-pressure system. The remnants of the storm crossed the Pacific and caused record rainfall in the San Francisco Bay Area and the Central California coast. A rare storm warning was posted for San Francisco Bay and subsequently, wind gusts were clocked at 77 mph on Angel Island. Damage is currently estimated at about $1.5 billion (2009 USD).

Tropical Storm Nepartak

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	October 8 – October 14
Peak intensity	85 km/h (50 mph) (10-min); 992 hPa (mbar)

On October 6, an area of convectional cloudiness associated with the monsoon trough formed 500 km (305 mi) to the southwest of Saipan. Satellite imagery showed a consolidating Low Level Circulation Center with formative convective banding and deep convection over the northern semi-circle. During in the morning of October 8, the system started to move northwest and it's LLCC rapidly became well defined due to favorable conditions. The JMA then upgraded it to a tropical depression, and the JTWC issued a TCFA on the system, as it had started to become better defined. Then in the evening of that day, it was upgraded into a tropical depression by the JTWC. On October 9, the JMA upgraded it to a tropical storm and assigned its international name Nepartak. After the JMA upgraded it to a tropical storm, it slowly intensified to a peak intensity of 50 mph (85 km/h), but dissipated on October 14, because the Polar Jet Stream had torn it apart.

Typhoon Lupit (Ramil)

Very strong typhoon (JMA)
Category 4 super typhoon (SSHWS)
Duration	October 14 – October 27
Peak intensity	175 km/h (110 mph) (10-min); 930 hPa (mbar)

Early on October 13, the JTWC reported that an area of convection had persisted about 380 nm to the northwest of Kwajalein. The convection was disorganised but was starting to consolidate around a broad low level circulation center within a favourable environment to develop further with good vertical windshear and favourable sea surface temperatures. The disturbance rapidly developed throughout that day with a Tropical Cyclone Formation Alert issued later that day by the JTWC before advisories were initiated early the next day by the JMA and the JTWC who designated it as Tropical Depression 22W before the JTWC reported that the depression had intensified into a weak tropical storm. On October 15, JMA upgraded it to a Tropical Storm with the name Lupit. On the afternoon of next day, JTWC reported that Lupit strengthened into a Category 1 typhoon. That evening, PAGASA started issuing warnings on Lupit as it entered into their area of responsibility and assigned its local name, Ramil. At the same time JMA also upgraded Lupit into a typhoon. Intensification continued due to favorable conditions and hot water conditions, then by October 17, it rapidly intensified into a Category 3-equivalent typhoon. In the morning of the next day, it strengthened into a Category 4 typhoon, then strengthened further to Super Typhoon classification. On October 20, Lupit weakened to a minimal typhoon. By the 24th, dry air entrainment and an unfavorable environment had weakened Lupit further to a strong tropical storm, and caused the storm to change track from its westward drift to accelerate northeastward. Later that day, JTWC and PAGASA has downgraded and issued final warning Lupit to an extratropical cyclone, but JMA continued to issue a on Lubit until early on October 27.

Tropical Depression

Tropical depression (JMA)
Duration	October 16 – October 20
Peak intensity	45 km/h (30 mph) (10-min); 1002 hPa (mbar)

Late on October 15, the JTWC reported that an area of convection had persisted about 780 km (485 mi) to the southeast of Hue, Vietnam. Convection was forming and wrapping into the low level circulation center and was moving into a favourable environment to develop with low vertical windshear and warm sea surface temperatures. It was then designated as a Tropical Depression by the JMA early the next morning as the low level circulation center was becoming exposed due to the high amounts of vertical windshear. A Tropical Cyclone Formation Alert was issued early on October 17 by the JTWC as the vertical windshear decreased, despite the low level circulation center being fully exposed. The Depression remained weak with the tropical cyclone formation alert being cancelled during October 19 before the depression dissipated on October 20.

Tropical Storm Mirinae

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	October 25 – Still Active
Peak intensity	75 km/h (45 mph) (10-min); 994 hPa (mbar)

Storm Names

Western North Pacific tropical cyclones are named by the RSMC Tokyo-Typhoon Center of the Japan Meteorological Agency. Names are selected from the following lists, there is no annual list. Names were contributed by 13 members of the ESCAP/WMO Typhoon Committee, except for Singapore. The 13 nations or territories, along with the Federated States of Micronesia, each submitted 10 names, which are used in alphabetical order by the English name of the country. The first storm and typhoon of the season was named Kujira. A storm was named Molave for the first time, the name having replaced Imbudo in 2003. Also, the name Goni was corrected from Koni. Names in bold are storms that are currently active, and unused names are marked in gray.

Philippines

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) uses its own naming scheme for tropical cyclones within its area of responsibility. Lists are recycled every four years. Typhoons Ondoy and Pepeng had their names retired after they both caused over 400 deaths in the Phillipines.

Season effects

This table lists all the storms that developed in the western Pacific Ocean to the west of the International Date Line during the 2009 season. It includes their intensity, duration, name, landfalls, deaths, and damages. All damage figures are in 2009 USD. Deaths in parentheses are indirect (a traffic accident, or landslide for example).
