The 1993 Pacific typhoon season was the most active season for the Philippines, seeing a total of 32 storms forming or entering their area of responsibility. Overall, it was an average season, spawning 28 tropical storms, 15 typhoons and three super typhoons. The season had no official bounds; it ran year-round in 1993, 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.

Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.

Duration	August 29 – September 7
Peak intensity	175 km/h (110 mph) (10-min); 925 hPa (mbar)

The monsoon trough formed a tropical depression on August 27. It headed generally westward, reaching tropical storm strength on the 30th and typhoon strength on the 31st. Yancy turned to the northeast, where it rapidly intensified to a 150 mph (240 km/h) super typhoon on the 2nd. The storm weakened to a 135 mph (217 km/h) typhoon before making landfall on southwestern Japan on the 3rd, and dissipated 2 days later over the Sea of Japan. Yancy brought strong winds to Japan, amounting to 42 casualties and widespread damage.

Severe Tropical Storm Zola (Unsing)

Severe tropical storm (JMA)
Tropical storm (SSHWS)
Duration	September 5 – September 9
Peak intensity	95 km/h (60 mph) (10-min); 985 hPa (mbar)

Zola was another weak system that hit Japan.

Typhoon Abe (Walding)

Very strong typhoon (JMA)
Category 3 typhoon (SSHWS)
Duration	September 9 – September 15
Peak intensity	155 km/h (100 mph) (10-min); 945 hPa (mbar)

Abe was another Typhoon that hit China.

Severe Tropical Storm Becky (Yeyeng)

Severe tropical storm (JMA)
Category 1 typhoon (SSHWS)
Duration	September 13 – September 18
Peak intensity	100 km/h (65 mph) (10-min); 980 hPa (mbar)

Becky struck China to the west of Macau at full force. The offshore waters in the southern and southwestern part of Hong Kong recorded hurricane-force winds where its hourly mean winds reached 122 km/h with gusts up to 176 km/h at Waglan Island. In Cheung Chau, winds increased significantly to 115 km/h hourly before undergoing maintenance; privately recorded its hourly winds of up to 128 km/h during its first hour of maintenance there in Cheung Chau, and up to 139 km/h 60-minute mean wind just before undergoing maintenance. In Tai Mo Shan, its hourly mean winds reached 155 km/h.

Becky was clearly underestimated and the hurricane signal 10 should have been hoisted as it was justified (hurricane-force winds recorded at southwestern part of Hong Kong when Becky traversed at about 110 km south-southwest of the Royal Observatory). Its maximum 10 minute sustained wind speed was estimated to be at around 150 km/h at its closet approach to Hong Kong.

The typhoon killed 1 taxi driver at a car accident in Hong Kong. As of 2017, Becky was revised and upgraded to a minimal typhoon.

Typhoon Dot (Anding)

Typhoon (JMA)

Category 1 typhoon (SSHWS)
Duration	October 1 – October 8
Peak intensity	120 km/h (75 mph) (10-min); 970 hPa (mbar)

Typhoon Flo hit the northern Philippines on October 4 as a minimal typhoon, having developed on the 28th from the monsoon trough. It stalled just off the west coast, and turned northeastward, becoming extratropical on the 9th. Flo caused at least 500 deaths from the heavy flooding on Luzon. Flo interacted with the nearby Ed, causing Flo to recurve eastwards. Flo’s recurving resulted prolonged rainfall across Luzon.

Tropical Storm Gene (Gundang)

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	October 7 – October 10
Peak intensity	65 km/h (40 mph) (10-min); 998 hPa (mbar)

Tropical Storm Jeana

Tropical storm (JMA)
Tropical storm (SSHWS)
Duration	November 5 – November 13
Peak intensity	85 km/h (50 mph) (10-min); 992 hPa (mbar)

Tropical depression (SSHWS)
Duration	November 13 – November 19
Peak intensity	45 km/h (30 mph) (1-min); 1002 hPa (mbar)

32W was long-lived.

Tropical Depression 33W

Tropical depression (SSHWS)
Duration	November 18 – November 19
Peak intensity	45 km/h (30 mph) (1-min); 1002 hPa (mbar)

Typhoon Kyle (Luring)

Typhoon (JMA)
Category 2 typhoon (SSHWS)
Duration	November 17 – November 24
Peak intensity	130 km/h (80 mph) (10-min); 960 hPa (mbar)

Kyle was yet another Philippines striking system. It also hit Vietnam.

Typhoon Lola (Monang)

Typhoon (JMA)
Category 3 typhoon (SSHWS)
Duration	December 1 – December 9
Peak intensity	150 km/h (90 mph) (10-min); 955 hPa (mbar)

The near equatorial trough spawned a tropical depression on November 27. It moved westward without significant development until December 2, when it became a tropical storm. Lola became a typhoon 2 days later, and hit the Philippines on the 5th. It weakened to a tropical storm after crossing the islands, but restrengthened to a 125 mph (200 km/h) typhoon before hitting southern Vietnam on the 8th. Lola quickly dissipated, not after causing 308 fatalities, 230 of which were in the Philippines from the heavy rains.

Typhoon Manny (Naning)

Typhoon (JMA)
Category 4 typhoon (SSHWS)
Duration	December 3 – December 16
Peak intensity	140 km/h (85 mph) (10-min); 960 hPa (mbar)

Manny, like Lola, developed from the near-equatorial trough on December 1. It headed westward, slowly strengthening to a tropical storm on the 4th. Due to a ridge to the north, it looped on the 7th and 8th and became a typhoon on the way. While heading southwestward towards the Philippines, Manny rapidly intensified to a 135 mph (220 km/h) typhoon before hitting the Philippines late on the 9th. It weakened over the islands, and upper level winds kept it from restrengthening much over the South China Sea. Manny dissipated on the 16th over the Malay Peninsula, after causing 230 deaths, only one week after Lola hit the same area.

Manny's track was unusual, given its time of year with a loop and a strengthening period to the southwest. However, it has a near-perfect analog; Typhoon Pamela in the 1982 Pacific typhoon season took a nearly identical track within days of Manny (though Pamela was much weaker than Manny).

Tropical Depression Oning

Tropical depression (PAGASA)
Duration	December 14 – December 16
Peak intensity	55 km/h (35 mph) (10-min);

A non-tropical system developed from the ITCZ of where Manny formed on December 11. It moved in a fairly fast westward direction as it gradually intensified into a weak tropical depression late on December 14. The PAGASA issued warnings on the depression as it reached peak intensity late on December 15, making landfall over the islands of Visayas.

Severe Tropical Storm Nell (Puring)

Severe tropical storm (JMA)
Category 1 typhoon (SSHWS)
Duration	December 20, 1993 – January 1, 1994
Peak intensity	110 km/h (70 mph) (10-min); 975 hPa (mbar)

Nell was the final system to hit the Philippines this year. 46 people were found dead due to Nell.

Storm names

During the season 28 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list which started on mid-1989.

Philippines

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 6 of which are published each year before the season starts. Names not retired from this list will be used again in the 1997 season. This is the same list used for the 1989 season. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked in gray.
