This article is about the 2005 hurricane. For other storms with this name, see Hurricane Katrina (disambiguation).

Hurricane Katrina was the eleventh named tropical storm, fourth hurricane, third major hurricane, and first Category 5 hurricane of the 2005 Atlantic hurricane season. It first made landfall as a Category 1 hurricane just north of Miami, Florida on August 25, 2005, then again on August 29 along the Central Gulf Coast near New Orleans, Louisiana, as a Category 4 storm. Katrina resulted in breaches of the levee system that protected New Orleans from Lake Pontchartrain, and most of the city was subsequently flooded by the lake's waters. This and other major damage to the coastal regions of Louisiana, Mississippi, and Alabama made Katrina the most destructive and costly natural disaster in the history of the United States.

The official death toll now stands at 1,274 and the damage higher than $200 billion, topping Hurricane Andrew as the costliest natural disaster in U.S. history. Over a million people were displaced — a humanitarian crisis on a scale unseen in the U.S. since the Great Depression.

In Louisiana, the hurricane's eye made landfall at 6:10am CDT on Monday, August 29. After 11:00am CDT, several sections of the levee system in New Orleans collapsed. Mandatory evacuation of New Orleans had been ordered by mayor Ray Nagin before the hurricane struck, on August 28. The order was repeated on August 31. By early September, people were being forcibly evacuated, mostly by bus to neighboring states.

Federal disaster declarations blanketed 90,000 square miles (233,000 km²) of the United States, an area almost as large as the United Kingdom. The hurricane left an estimated five million people without power, and it may take up to two months for all power to be restored. On September 3, Homeland Security Secretary Michael Chertoff described the aftermath of Hurricane Katrina as "probably the worst catastrophe, or set of catastrophes" in the country's history, referring to the hurricane itself plus the flooding of New Orleans.

The U.S. National Hurricane Center (NHC) reported on August 23 that Tropical Depression Twelve had formed over the southeastern Bahamas. The numbering of the system was debated, as Tropical Depression Twelve formed partially from the remains of Tropical Depression Ten. The naming and numbering rules at the NHC require a system to keep the same identity if it dies, then regenerates, which would normally have caused this storm to remain numbered Ten. However, the NHC gave this storm a new number because a second disturbance merged with the remains of Tropical Depression Ten on August 20, and there is no way to tell whether the remnants of Tropical Depression Ten should be credited with this storm. (This is different from Hurricane Ivan in the 2004 season, when the NHC ruled that Ivan did indeed reform; the remnant of Ivan that regenerated in the Gulf of Mexico was a distinct system from the moment Ivan originally dissipated to the moment it regained tropical storm strength.) The system was upgraded to Tropical Storm Katrina on the morning of August 24. Katrina became the fourth hurricane of the 2005 season on August 25 and made landfall later that day around 6:30 p.m. between Hallandale Beach and Aventura, Florida.

Katrina weakened over land on August 26, becoming a tropical storm before growing to a Category 2 hurricane with winds of 100 mph. It became clear the storm was headed for Mississippi and Louisiana.

On August 27, the storm was upgraded to Category 3 intensity (major hurricane) and at 12:40 a.m. CDT (0540 UTC) on August 28, Katrina was upgraded to Category 4. Later that morning, Katrina went through a period of rapid intensification, becoming a Category Five storm on theSaffir-Simpson Hurricane Scale. Katrina had maximum sustained winds of 175 mph (280 km/h), gusts of 215 mph (344 km/h) and a central pressure of 26.75 inches, or 906 mbar (hPa), by 1:00 p.m. CDT. It later reached a minimum pressure of 26.64 inches (902 mbar), making it the fifth most intense Atlantic Basin hurricane on record. Katrina's rapid intensification was due in part to its movement over the Gulf Loop Current.

Katrina made landfall on August 29 as a Category 4 hurricane with sustained winds of 145 mph (235 km/h) with higher gusts, at 6:10 a.m. CDT near Buras-Triumph, Louisiana. Making its way up the eastern Louisiana coastline, most communities in Plaquemines and St. Bernard Parish, and Slidell in St. Tammany Parish, were severely damaged by storm surge and the strong winds of the eyewall, which also grazed eastern New Orleans. A few hours later, it made landfall for a third time near the Louisiana/Mississippi border with 125 mph (200 km/h) Category 3 sustained winds. However, because the storm was so large, extreme damaging eyewall winds and the strong northeastern quadrant of the storm, pushing record storm surges onshore, smashed the entire Mississippi Gulf Coast, including towns in Mississippi such as Waveland, Bay St. Louis, Pass Christian, Long Beach, Gulfport, Biloxi, Ocean Springs, Gautier and Pascagoula, and, in Alabama, Bayou La Batre. As Katrina moved inland diagonally over Mississippi, high winds cut a swath of damage that affected almost the entire state.

Katrina weakened thereafter, losing hurricane-strength more than 150 miles (160 km) inland, near Jackson, Mississippi. It was downgraded to a tropical depression near Clarksville, Tennessee and continued to race northward.

Katrina continued to affect the central US as it moved north, and was last seen in the eastern Great Lakes region on August 31. Before being absorbed by a frontal boundary, Katrina's last known position was over southeast Quebec and northern New Brunswick. On August 31, Katrina became a powerful extratropical low on province of Quebec that gave 50 to 170 mm (1.97 to 6.69 in) of rain in 12 hours; also numerous wind gust from 50 to 98 km/h (31 to 61 mph) were reported in southern and eastern Quebec. In the region of Saguenay and Cote-Nord rain caused breakdown and failure in roads. The Cote-Nord region was isolated from rest of Quebec for at least 1 week.

Its lowest minimum pressure at landfall was 27.108 inches (918 mbar) (hPa), making it the third strongest hurricane on record to make landfall on the United States. A 10 to 30 foot (3 to 10 m) storm surge came ashore on over 200 continuous miles of coastline, from southeast Louisiana, including Mississippi and Alabama, through to the Florida panhandle. The 37 foot (>10 m) storm surge recorded at Pass Christian, Mississippi is the highest ever observed in America. Pass Christian is the same town that suffered a 25 ft. storm surge in the second strongest hurricane (Camille, 1969) to hit the United States. Record storm surges that had not occurred in at least the last 150 years, inundated the entire Mississippi coastline, destroying many historic homes. The storm surge in Mobile, Alabama was the highest in that location since 1917, besting the category 3 Hurricane Frederic which hit the city directly in 1979.

At 11 p.m. EDT on August 31 (0300 UTC, September 1), U.S. government weather officials announced that the center of the remnant low of what was Katrina had been completely absorbed by a frontal boundary in southeastern Canada, with no discernible circulation. The Hydrometeorological Prediction Center's last public advisory on Katrina was at 11 p.m. EDT on August 31 and the Canadian Hurricane Centre's last public advisory on Katrina was at 9 a.m. EDT on August 31.

Tornadoes

There were at least 36 confirmed tornadoes associated with Hurricane Katrina, with 11 tornadoes in Mississippi, 4 tornadoes in Alabama, 15 tornadoes in Georgia, 1 tornado in Virginia, and 5 tornadoes in Pennsylvania. Most of the tornadoes were rated F0 or F1, but three tornadoes were rated F2 in Georgia, and two were rated F2 in Mississippi. Tornadoes were reported in places including Adams and Cumberland counties in Pennsylvania, in Fauquier, Virginia, in Carroll County, Georgia, in Carrollton, in White County, Georgia, in Helen, and in Fort Valley, Georgia. Several other weak tornadoes were reported by tv stations in and around Mobile, Alabama and Harrison County, Mississippi. There were also reports of tornado touch downs in parts in Harvey, Louisiana, a town of the West Bank of the Mississippi River, just south of New Orleans.

One death was reported from an F2 tornado near Roopville, Georgia in Carroll County, and 500,000 chickens were killed or set free after about 15 poultry houses were damaged. Several injuries were reported with other tornadoes across Georgia. There was major damage in Helen, Georgia by an F2 tornado, which destroyed homes and a hotel. In Fort Valley, Georgia, another tornado ripped through a credit union and destroyed local houses and trees.

The tornado outbreak set new monthly records in Georgia, including the most reported on a single day in August, the state's first death from an August tornado, and the most tornado damage (monetarily) ever in August.

Preparations and expectations before landfall

Advance weather forecasts

Template:Wikinewshas

Many living in the area felt that south Florida had minimal advance warning when Katrina strengthened from a tropical storm to a hurricane in one day, and struck southern Florida later that same day, on August 25. Even so, NHC forecasts showed Katrina strengthening into a hurricane well in advance of landfall, and hurricane watches and warnings were indeed issued nearly 36 and 24 hours, respectively, before hurricane conditions were felt in the area (watches and warnings are supposed to be issued at those time periods),.

On August 27, after Katrina crossed southern Florida and strengthened to Category 3, President George W. Bush declared a state of emergency in Louisiana, Alabama, and Mississippi two days before the hurricane made landfall. On August 28 the National Weather Service issued a bulletin predicting "devastating" damage rivaling the intensity of Hurricane Camille. At a news conference New Orleans Mayor Nagin ordered an unprecedented mandatory evacuation of the city with Gov. Blanco standing beside him.

Evacuation and emergency shelters

"Not since the Dust Bowl of the 1930s or the end of the Civil War in the 1860s have so many Americans been on the move from a single event."

At a news conference 10 a.m. on August 28, shortly after Katrina was upgraded to a Category 5 storm, New Orleans mayor C. Ray Nagin, calling Katrina "a storm that most of us have long feared," ordered the first ever mandatory evacuation of the city. Contraflow lane reversal on Interstate 10 leading west and Interstates 55 and 59 leading north from New Orleans was ended that afternoon.

Two weeks after the storm, over half the States were involved in providing shelter for evacuees. By four weeks after the storm, evacuees had been registered in all 50 states and in almost half the Zip codes of the U.S. Three quarters of evacuees had stayed within 250 miles but tens of thousands had located more than 1000 miles away.

Roughly 150,000 people were not able to evacuate, partially because hundreds of available New Orleans school buses were not used in the evacuation . According to NBC's veteran reporter Lisa Myers, "A draft emergency plan, prepared by the Federal Emergency Management Agency and obtained by NBC News, calls for '400 buses to ... evacuate victims.' Yet those 400 buses were left in Katrina's path." Myers reports New Orleans Mayor Nagin refused comment on the matter.

While some have claimed school bus drivers were not available, the very first bus to arrive at the Reliant Astrodome with New Orleans evacuees was a New Orleans school bus driven by an evacuee, 20 year old Jabbar Gibson, who commandeered it. Any licensed driver is suitable in an emergency.

In addition to residents, many tourists were stranded. Fuel and rental cars were in short supply; also, Greyhound bus and Amtrak train service were halted well before the hurricane made landfall . Future analysis of motor vehicle registration, census and Social Security Information, and death certificates may help to provide more clarity. During the Hurricane Ivan evacuation, 600,000 people remained in the city .

Mandatory evacuations were also ordered for Assumption, Jefferson (Kenner, Metairie, as well as Grand Isle and other low lying areas), Lafourche (outside the floodgates), Plaquemines, St. Charles and St. James parishes and parts of St. Tammany, Tangipahoa and Terrebonne parishes in Louisiana.

In Alabama, evacuations were ordered for parts of Mobile and Baldwin counties (including Gulf Shores). In Mississippi, evacuations were ordered for parts of Hancock, Harrison, Pearl River and Jackson counties.

New Orleans shelters

Louisiana Superdome

On August 28, as Hurricane Katrina grew into a Category 5 storm that had yet to make landfall, Nagin established several "refuges of last resort" for citizens who could not leave the city, including the massive Louisiana Superdome. The New Orleans Times - Picayune reported that the Louisiana National Guard delivered three truckloads of water and seven truckloads of MRE's, enough to supply 15,000 people for three days according to Col. Jay Mayeaux, deputy director of the Department of Homeland Security's Office of Emergency Preparedness . The Superdome housed over 9,000 people along with 550 National Guard troops when Katrina came ashore . On August 29, Katrina passed over New Orleans with such force that it ripped two holes in the Superdome roof. A National Guard official said on Thursday, September 1, that as many as 60,000 people had gathered at the Superdome for evacuation, having remained there in increasingly difficult circumstances , , . Air conditioning, electricity, and running water all failed, making for very unsanitary and uncomfortable conditions. There have been widespread reports of murders, rapes, beatings, robberies, and general mayhem in the Superdome, though most reports appear in the foreign press, as mainstream U.S. media have omitted the more serious reports. Most of these reports were determined to be based on unverified rumors and myths . By late September, it had become clear that nearly all of the murder, rape, and other crime rumors were false On August 31, it was announced that evacuees would be moved to the Astrodome in Houston, Texas. During this evacuation many owners were seperated from their pets, and the plight of Snowball (Hurricane Katrina dog) was widely reported. By September 6, the Superdome was completely evacuated. Officials say that the flood damage, debris, human waste and bodily fluids in the Superdome is a "potential biohazard," and that it is too early to tell what the final fate of the structure will be, although demolition has been cited as a possible outcome.

New Orleans Convention Center

The New Orleans Convention Center was broken into by August 30th, and by September 1, the facility, like the Superdome, was overwhelmed and declared unsafe and unsanitary. Reports of violence, beatings, and rape among those gathered in the convention center were widespread. Several people died while sheltered within. Reports indicated that up to 20,000 people had gathered at the Convention Center, many dropped off after rescue from flooded areas of the city. Others were directed to the center by the police, headed by Eddie Compass, as a possible refuge. However, even though there were thousands of evacuees at the center, along with network newscasters, pleading desperately for help on CNN, FOX, and other broadcast outlets, FEMA head Michael Brown and Homeland Security Secretary Michael Chertoff both claimed to have no knowledge of the use of the Convention Center as a shelter until the afternoon of September 1 (CNN Video), although later Brown said he misspoke and had learned of them 24 hours earlier. For two days, still, the evacuees' pleas were ignored. Those able to walk the distance could have left the Convention Center, and the city, via the Crescent City Connection Bridge, but were prevented from doing so at gunpoint by Gretna, LA sheriffs . The Convention Center was completely evacuated by September 3. By September 8 there were reports that the claims of rape and murder at the Convention Center and the Superdome could be false . By late September, it was found that nearly all of these claims were in fact false.

Shelters in Texas

On August 31, the Harris County, Texas Department of Homeland Security and Emergency Management and the State of Louisiana came to an agreement to allow at least 25,000 evacuees from New Orleans, especially those who were sheltered in the Louisiana Superdome, to move to the Astrodome until they could return home. The evacuation began on September 1.

However, as of September 2, officials declared the Reliant Astrodome full and unable to accept additional hurricane refugees from the disaster. The Reliant Astrodome was reopened a few hours later, and it was announced that the Reliant Center would have all events cancelled through December so as to open the building to ~11,000 additional evacuees. The George R. Brown Convention Center was announced as an additional shelter site at the same time, but was not opened for use until September 3.

When the Houston shelters began to reach capacity on September 2, Texas Governor Rick Perry activated an emergency plan that made space for an additional 25,000 in each of San Antonio and the Dallas/ Fort Worth/ Arlington,TX Metroplex and smaller shelters in communities across Texas. Beginning with a convoy of 50 buses (2,700 people) that arrived at the Dallas Reunion Arena at 3:00 a.m. CST September 3, a wave of over 120,000 additional evacuees began pouring into Texas at a rate, such that as of September 5, it was estimated there are roughly 139,000 evacuees in official shelters in the state, adding to the estimated 90,000 already in hotels and homes.

By the afternoon of September 5, with a total estimated number of over 230,000 evacuees in Texas, Governor Perry ordered that buses begin being diverted to other shelters outside the state resulting in 20,000 being sent to Oklahoma and 30,000 being sent to Arkansas. By Labor Day, September 6, Texas had an estimated 250,000 evacuees and Governor Perry was forced to declare a state of emergency in Texas and issued an impassioned plea to other states to begin taking the 40,000-50,000 evacuees that were still in need of shelter.

Local effects and aftermath

Areas affected include southern Florida, Louisiana (especially the Greater New Orleans area), Mississippi, Alabama, the western Florida Panhandle, western and north Georgia (hit by tornadoes), the Tennessee Valley and Ohio Valley regions, the eastern Great Lakes region and the length of the western Appalachians. Over 1,200 deaths have been reported in seven states, a number which is expected to rise as casualty reports come in from areas currently inaccessible. Three levees in New Orleans gave way, and 80% of the city was under water at peak flooding, which in some places was 20 to 25 feet (7 or 8 meters) deep. As of September 6, the flood pool had abated to covering 60% of the city.

By September 2, NOAA had published satellite photography of many of the affected regions. The storm surge in Katrina as it was making landfall on August 29 was very high to the east of where the storm center crossed the coast. Storm surge of near 30 feet high was observed, where during the height of the storm at the Mississippi Coast Coliseum scenes like a car floating outside the first floor lobby, and a boat is being swept across the parking lot as the surge comes in with the eyewall winds were not uncommon. The lobby and parking lot are over 20 feet above sea level of the Gulf of Mexico, and 1/4 mile away from the Gulf coastal road Highway 90 in Harrison County between Biloxi and Gulfport.

Looting and violence

The neutrality of this section is disputed. Relevant discussion may be found on the talk page. Please do not remove this message until conditions to do so are met. (Learn how and when to remove this message)

Shortly after August 30, there were reports that some of the thousands of people who remained in the city, including police officers, began taking items from stores . The activies were initially reported exclusively as looting, and television news media aired some highly convincing images that looting was taking place. A temporary jail was constructed of chain link cages in the city train station

The confirmed death toll as of October 7 stands at 1,242, mainly from Louisiana (1,003) and Mississippi (221Direct deaths indicate those caused by the direct effects of the winds, flooding, storm surge or oceanic effects of Katrina. Indirect deaths indicate those caused by hurricane-related accidents (including car accidents), fires or other incidents, as well as clean-up incidents and health issues.

Government officials had estimated fatalities as high as 10,000. The fear that thousands of people died has proven to be an urban legend.

Health concerns

Aside from the lack of water, food, shelter, and sanitation facilities, there was concern that the prolonged flooding might lead to an outbreak of health problems for those who remained in the hurricane-affected areas. In addition to dehydration and food poisoning, there was potential for communicable disease outbreaks of diarrhea and respiratory illness, all related to the growing contamination of food and drinking water supplies in the area.

President Bush declared a emergency for the entire Gulf Coast. Before the hurricane, government health officials prepared to respond, and the Centers for Disease Control and Prevention (CDC) began sending medical emergency supplies to locations near the worst-hit area within 48 hours after landfall.

Supplies shipped by CDC's Strategic National Stockpile provided pharmaceuticals, technical assistance teams, and treatment capacity for citizens otherwise stranded by the hurricane's catastrophic effect on hospital infrastructure in Louisiana and Mississippi. CDC's supplies served an estimated 30 acute care hospitals south of Interstate Highway 10, and volunteers organized around its "contingency stations" to become temporary stand-ins for hospitals, warehouses, and distribution facilities damaged by the storm. Alongside strong responses from state and local medical teams, CDC support remained crucial until normal infrastructure support began to return a week and a half later.

Within days after landfall, medical authorities established contingency treatment facilities for over 10,000 people, and plans to treat thousands more were developing. Partnerships with commercial medical suppliers, shipping companies, and support services companies insured that evolving medical needs could be met within days or even hours.

Animal concerns

As with any major disaster, animals are affected as well as human beings. In the case of Katrina no order to support total animal evacuation was given.

How the many hundreds of thousands of victims of Katrina who have lost all their possessions will cope with wage reductions is unknown . The economic loss will force many survivors into bankruptcy. Those with jobs will have to pay if their income is $100 over the states' median income. Louisiana and Mississippi have some of the lowest median incomes in the nation requiring Katrina victims to pay creditors whereas in most US states with a similar income person will pay nothing. Treasury Secretary John Snow said "that though the hurricane might have suddenly driven some Gulf Coast residents to file for bankruptcy," "the new law shouldn't be delayed or changed." The Treasury office will not help Hurricane Katrina victims with debt cancellation. Hurricane jobless claims in late August, totaled over 190,000. No debt cancellation is expected for the victims of Hurricane Katrina. They will be given a payment deferral for up to 90 days.Opponents of the bill also argued that it makes the government "a bill collector for private companies", and could lead to criminal prosecutions over matters best left in civil courts, and theoretically even to life imprisonment under federal three-strikes laws.

Disaster response

Some disaster recovery response to Katrina began before the storm, with Federal Emergency Management Agency preparations that ranged from logistical supply deployments to a mortuary team with refrigerated trucks. A network of volunteers have been rendering assistance to local residents and residents emerging from New Orleans and surrounding Parishes.

In accordance with federal law, President George W. Bush directed Secretary Michael Chertoff of the Department of Homeland Security to coordinate the Federal response. Chertoff designated Michael D. Brown, head of the FEMA as the Principal Federal Official to lead the deployment and coordination of all federal response resources and forces in the Gulf Coast region. However, the President and Secretary Chertoff have come under harsh criticism from many Americans, particularly in the media, for their lack of planning and coordination. Eight days later, Michael D. Brown was recalled to Washington and Coast Guard Vice Admiral Thad W. Allen replaced him as chief of hurricane relief operations. Three days after the recall, Michael D. Brown resigned as director of FEMA in spite of having received praise from President George W. Bush .

USNORTHCOM established Joint Task Force (JTF) Katrina based out of Camp Shelby, Mississippi to act as the military's on-scene command on Sunday, August 28 . Lieutenant General Russel Honoré of the U.S. First Army in Fort Gillem, Georgia, is the commander.

The U.S. Senate approved a bill authorizing $10.5 billion in aid for victims on September 1 2005. The U.S. House of Representatives voted and approved on the measure Friday, September 2 2005 without any debate; Bush signed it into law an hour later. On September 7, another $51.8 billion in addition to the original $10.5 billion was proposed by President Bush to fund disaster relief.

In addition to asking for federal funds, President Bush has enlisted the help of former presidents Bill Clinton and George H.W. Bush to raise additional voluntary contributions, much as they did after the 2004 Indian Ocean earthquake and tsunami. On September 3, Gov. Blanco hired James Lee Witt, the former FEMA director during the Clinton Administration, to oversee recovery efforts in Louisiana. .

Many U.S. states have offered to shelter evacuees displaced by the storm, including places as far away as Oregon, whose offer to take one thousand refugees, according to Portland-area news organizations, was later declined, and California. The majority of the evacuees from this crisis were taken to Texas, with over 230,000 persons being sheltered in Texas by Labor Day, September 5 2005. As Texas became filled to capacity, it became a waypoint for the other evacuees still leaving the area of crisis. From Texas, thousands of evacuees are being dispersed to other states.

An estimate of over 100,000 New Orleans college and university students have been displaced as a result of Hurricane Katrina. Higher institutions from across the U.S. have opened their doors to enroll students displaced as a result of Hurricane Katrina. See list compiled by Wikinews.

Army and Air National Guard troops have been activated from nearly every state in the union.

International response

Over seventy countries pledged money or other assistance

The American Red Cross, Salvation Army, and many other charitable organizations are trying to provide housing, food, and water to the victims of the storm. However, in the Algiers neighborhood of New Orleans the US military, FEMA, and the Red Cross are sending people needing help over to a tent set up by anarchists, dubbed the "Mayday Mutual Aid Medical Station," located in front of the Masjib Bilal Mosque. These organizations provided an infrastructure for shelters throughout Louisiana and other states that held thousands of evacuees. On September 8, 2005, FOX News reported that the Red Cross was prepositioned to provide water, food and essential supplies to the Superdome and convention center as soon as the storm finished, but was prohibited from entering the city prior to Hurricane Katrina making landfall by the Louisiana State Department of Homeland Security, under the direction of Louisiana Governor Kathleen Blanco. The safety of Red Cross personnel was among the primary reasons given. Within days of the hurricane Community Wireless Network organizations from across North America self-mobilized to deploy telecommunications infrastructure in evacuee camps throughout the region.

Along the MS Gulf Coast, needed supplies including water, food, cleaning items, diapers, clothing, blankets, and even chain saws, generators, flashlights, and batteries were immediately brought in during the first days, by a nationwide spontaneous outpouring from private individuals and religious organizations, concerned at the lack of visibility of the MS coastal devastation by the media, and lack of immediate disaster response. Distribution points were set up at churches, well before the Red Cross had set up distribution centers, as reported by the Mississippi Press It Takes A Disaster, Help May Arrive in Gautier Today, and Florida Couple Fulfills Mission of Mercy.

Effects outside the immediate region

Template:Costliest hurricanes

Economic effects

Most experts anticipate that Katrina will be the costliest natural disaster in U.S. history. Some early predictions in damages exceeded $100 billion, not accounting for potential catastrophic damage inland due to flooding (which would increase the total even more), or damage to the economy caused by interruption of oil supply (much of the U.S. energy operations are in the Gulf Coast region), and exports of commodities such as grain. Other predictions placed the minimum insured damage at around $12.5 billion (the insured figure is normally doubled to account for uninsured damages in the final cost). There are also effects on ocean shipping, the casino industry and tourism.

International oil prices rose. In the UK pump prices for unleaded petrol (gas) hit £1 per litre ($7 per US gallon) for the first time in a significant number of places (averaging about 95p), a rise of about 3% from pre-Katrina prices. Wholesale prices were up 5% as of 6 September.

Space Shuttle Program

The hurricane passed over the Michoud Assembly Facility and materially interrupted the production of external tanks for the Space Shuttle, leading to a further interruption of the shuttle flights . Evan McCollum, a Lockheed Martin Space Systems spokesman in Denver reported on August 292005 that "there is water leakage and potential water damage in the buildings, but there's no way to tell how much at this point" .

The Michoud Assembly Facility remained closed until September 26, at which time only essential staff were called back to the facility. On September 16, 2005 NASA announced that the repairs were progressing faster than anticipated, and so they will continue to use Michoud for external tank work . The next Shuttle flight, STS-121, may still be postponed to May or later during the second half of 2006 . This facility is also used as a temporary staging area and headquarters for the U.S. Marine Corps effort in New Orleans, helping with the evacuation.

The John C. Stennis Space Center in Hancock County, Mississippi was also damaged by Katrina, with structural damage to the main facility causing some water leakage into the interior portions of the research facility and halting any major tests while repairs are being made. In addition, the space center was used as a temporary evacuation center for areas near the Mississippi gulf coast region and for residents of New Orleans.

http://www.cybertelecom.org/security/katrina.htm] The NO Visitor's Bureau reports "There is virtually total internet disruption as well, as locally hosted servers and routers have gone down with the loss of primary and backup power. Only those hotels with corporate housed servers in other cities have any internet possibility."

Cybertelecom.org has established a webpage to collect data on the status of and impact on the Internet. .

Science research

Important work on heart disease, cancer, AIDS and many other other ailments may be lost to scientists at Tulane and Louisiana State universities' medical schools in New Orleans. Military research was also affected as state police broke into a high-security government lab in New Orleans and destroyed unspecified dangerous pathogens before they could escape or be stolen.

Political effects

As high profile news coverage has reported, the American public in general blames all levels of government in different proportions for failures to perform their responsibilities in hurricane preparedness, reaction, and aftermath.

Prevention and evacuation issues

According to the National Response Plan, the Department of Homeland Security "will assume primary responsibility on March 1st for ensuring that emergency response professionals are prepared for any situation. This will entail providing a coordinated, comprehensive federal response to any large-scale crisis and mounting a swift and effective recovery effort" . The state evacuation plan (Part 1 Section D7) states , evacuation is the responsibility of the local parish. In Orleans Parish that responsibility fell to Mayor Ray Nagin. Many critics have noted that while Mayor Nagin gave a mandatory evacuation order on August 28, before the storm hit, they did not make sufficient prevention and provisions to evacuate the homeless, the poor, the elderly, the infirm, or the car-less households. Hospitals, nursing homes, group homes, were supposed to have pre-determined evacuation and/or refuge plans in place. page II-3 Foreign nationals without transport claimed that the police refused to evacuate them, giving bus places only to American citizens.

Prior to this, on August 27 the White House issued a statement , effective August 26, authorizing federal emergency assistance for Louisiana. The statement authorized the DHS and FEMA to coordinate disaster relief and "...required emergency measures, authorized under Title V of the Stafford Act, to save lives, protect property and public health and safety, or to lessen or avert the threat of a catastrophe in the parishes of Allen, Avoyelles, Beauregard, Bienville, Bossier, Caddo, Caldwell, Claiborne, Catahoula, Concordia, De Soto, East Baton Rouge, East Carroll, East Feliciana, Evangeline, Franklin, Grant, Jackson, LaSalle, Lincoln, Livingston, Madison, Morehouse, Natchitoches, Pointe Coupee, Ouachita, Rapides, Red River, Richland, Sabine, St. Helena, St. Landry, Tensas, Union, Vernon, Webster, West Carroll, West Feliciana, and Winn." This includes all the parishes in the state of Louisiana except the coastal parishes which are inherently exposed to the most destructive forces of a hurricane. The President had not yet authorized FEMA to enter the coastal areas despite the governors request including those parishes. The governor activated the National Guard with her August 26, State of Emergency Declaration page II-4 Red Cross relief in New Orleans remains forbidden by the Governor.

According to the Louisiana Emergency Operations Plan, evacuation was mainly left up to individual citizens to find their own way out of the city. It was known that many residents of New Orleans lacked cars. It is also believed that many citizens, having survived previous hurricanes, did not anticipate the impending catastrophe and chose to ride out the storm. Even so, a 2000 census revealed that 27% of New Orleans households, amounting to approximately 120,000 people, were without privately-owned transportation. Additionally, at 38%, New Orleans has one of the highest poverty rates in the United States. These factors may have prevented many people from being able to evacuate on their own. Consequentially most of those stranded in the city are the poor, the elderly, and the sick.

Some school buses were left parked on low ground where they would be easily flooded with storm water and then later by the levee flooding making their use impossible in the emergency evacuation after the rupture of the levee, sparking claims that Mayor Nagin did not follow some plan, but such a plan would necessarily require interstate coordination . It is not clear whether these buses were owned by the city or by a private contractor to which the city had outsourced school bus services. The number of these buses has been greatly exaggerated possibly in an attempt to smear Mayor Nagin. Mayor Nagin did send city buses from New Orleans' Regional Transit Authority to help shelter those that stayed behind. These buses were intended to bring the remaining people to the Superdome for a last haven and for relief, but the dome was stocked with few relief supplies. Many supporters also note that school buses, while powerful, can be difficult to control in normally high windspeed of 50-80 mph (80-120 km/h). Winds west of New Orleans were recorded at 50mph during the storm and approximately 10 mph after the storm but before the levee break. During non-emergency times, drivers of school buses must own and maintain a class D commercial license or better depending on the exact size and weight of the bus. During an emergency any driver is suitable as long as OK'd by the Governor Kathleen Blanco.

In spite of risks and his lack of formal training or license, 20-year-old Jabbar Gibson commandeered a New Orleans school bus and rescued 70 people from the rising flood waters before making the 13-hour drive to Houston's Reliant Astrodome, arriving on Wednesday evening. A day later a commercially licensed driver's bus filled with evacuees flipped, resulting in one death and many injuries after a passenger fought with the driver.

Environmental issues

Katrina has caused a renewed interest in global warming and whether it is responsible for stronger hurricanes observed in recent years. See discussion on Long term trends in cyclone activity for more information.

An environmental factor in the extent of damage caused by Katrina has been the destruction of wetlands in the affected regions, which traditionally have a mitigating effect on hurricane damage acting as a sponge to slow floodwaters.

Untreated sewage, decomposing bodies and livestock as well as a complicated mixture of toxic chemicals and oils originating from both domestic, agricultural and industrial sources are still mixing into the floodwaters creating a serious health risk across the whole of the flooded area. The immediate threats include disease contagions being spread from decomposing bodies, both by water and by animal vectors such as mosquitoes. Longer term threats will reveal themselves as the floodwaters recede, including biochemical residue which could severely impact surface and ground water, soil, and urban environments. An immediate challenge exists in safely disposing of vast quantities of polluted water inside New Orleans. Many news reports currently state that the water inside New Orleans will be pumped straight back into Lake Pontchartrain and the Gulf of Mexico. The effects of this action remain extremely unclear and could result in serious contamination of both bodies of water.
