{{Katrina}}
'''Hurricane Katrina''' was the costliest and one of the deadliest [[tropical cyclone|hurricane]]s in the history of the [[United States]]. It was the sixth-strongest [[Atlantic hurricane]] ever recorded and the third-strongest landfalling U.S. hurricane ever recorded. Katrina formed in late August during the [[2005 Atlantic hurricane season]] and devastated much of the north-central [[Gulf Coast of the United States]]. Most notable in media coverage were [[effect of Hurricane Katrina on New Orleans|the catastrophic effects]] on the city of [[New Orleans, Louisiana]]. Katrina's sheer size devastated the [[Gulf Coast of the United States|Gulf Coast]] over 100 miles (160 km) away from its center.
Katrina was the eleventh named storm, fifth hurricane, third [[Tropical cyclone#Categories and ranking|major hurricane]], and second [[Saffir-Simpson Hurricane Scale|Category 5 hurricane]] of the 2005 Atlantic season. It formed over the [[Bahamas]] on [[August 23]], [[2005]], and crossed southern [[Florida]] as a moderate [[Saffir-Simpson Hurricane Scale|Category 1 hurricane]] before strengthening rapidly in the [[Gulf of Mexico]] and becoming one of the strongest hurricanes ever recorded in the Gulf. The storm weakened considerably before making its second and third landfalls as a Category 3 storm on the morning of [[August 29]] in southeast Louisiana and at the Louisiana/Mississippi state line, respectively.
The storm surge caused severe or catastrophic damage along the coastlines of [[Alabama]], [[Mississippi]] and [[Louisiana]], including the cities of [[Mobile, Alabama|Mobile]] (Alabama), [[Biloxi, Mississippi|Biloxi]] and [[Gulfport, Mississippi|Gulfport]] (Mississippi), and [[Slidell, Louisiana|Slidell]] (Louisiana). [[Levee]]s separating [[Lake Pontchartrain]] and Lake Borgne from New Orleans were breached by the surge, ultimately flooding 80% of the city and many areas of neighboring [[civil parish|parishes]]. Severe wind damage was reported well inland. Katrina is estimated to be responsible for $81.2 billion (2005 [[United States dollar|US dollars]]) in damages, making it the costliest hurricane in U.S. history. The storm killed at least 1,836 people, making it the deadliest U.S. hurricane since the [[1928 Okeechobee Hurricane]]. Criticism of the federal, state and local governments' reaction to the storm was widespread and resulted in an investigation by the [[United States Congress]] and the resignation of [[FEMA]] head [[Michael D. Brown|Michael Brown]].
==Storm history==
{{main|Meteorological history of Hurricane Katrina}}
{{storm path|Katrina 2005 track.png}}
Hurricane Katrina formed as Tropical Depression Twelve over the southeastern Bahamas on [[August 23]], [[2005]] as the result of an interaction of a [[tropical wave]] and the remains of [[List of 2005 Atlantic hurricane season storms#Tropical Depression Ten|Tropical Depression Ten]]. The system was upgraded to [[Tropical cyclone#Intensity classifications|tropical storm status]] on the morning of [[August 24]] and at this point, the storm was given the name ''Katrina.'' The tropical storm continued to move towards Florida, and became a hurricane only two hours before it made [[landfall (meteorology)|landfall]] between [[Hallandale Beach, Florida|Hallandale Beach]] and [[Aventura, Florida]] on the morning of [[August 25]]. The storm weakened over land, but it regained hurricane status about one hour after entering the [[Gulf of Mexico]].{{cite web|last=Knabb|first=Richard D|coauthors=Rhome, Jamie R.; Brown, Daniel P|url=http://www.nhc.noaa.gov/pdf/TCR-AL122005_Katrina.pdf|format=PDF|title=Tropical Cyclone Report: Hurricane Katrina: 23-30 August 2005|publisher=[[National Hurricane Center]]|date=[[December 20]], [[2005]]|accessdate=2006-05-30}}
The storm [[rapid deepening|rapidly intensified]] after entering the Gulf, in part due to the storm's movement over the warm [[sea surface temperature|water]]s of the [[Loop Current]].Leben, Robert; Born, George; Scott, Jim. "[http://www.colorado.edu/news/releases/2005/358.html CU-Boulder Researchers Chart Katrina's Growth In Gulf Of Mexico]." ''[[University of Colorado at Boulder]].'' [[September 15]], [[2005]]. Retrieved on [[2006-06-05]]. On [[August 27]], the storm reached Category 3 intensity on the [[Saffir-Simpson Hurricane Scale]], becoming the third [[Tropical cyclone#Categories and ranking|major hurricane]] of the season. An [[eyewall#Eyewall replacement cycles|eyewall replacement cycle]] disrupted the intensification, but caused the storm to nearly double in size. Katrina again rapidly intensified, attaining Category 5 status on the morning of [[August 28]] and reached its peak strength at 1:00 p.m. CDT that day, with maximum sustained winds of 175 mph (280 km/h) and a minimum central [[atmospheric pressure|pressure]] of 902 [[mbar]]. The pressure measurement made Katrina the fourth most intense [[Atlantic hurricane]] on record at the time, only to be surpassed by Hurricanes [[Hurricane Rita|Rita]] and [[Hurricane Wilma|Wilma]] later in the season; it was also the strongest hurricane ever recorded in the Gulf of Mexico at the time as well (a record also later broken by Rita).
Katrina made its second landfall at 6:10 a.m. CDT on [[August 29]] as a Category 3 hurricane with sustained winds of 125 mph (205 km/h) near [[Buras-Triumph, Louisiana]]. At landfall, hurricane-force winds extended outward 120 miles (190 km) from the center and the storm's central pressure was 920 mbar. After moving over southeastern Louisiana and [[Breton Sound]], it made its third landfall near the Louisiana/Mississippi border with 120 mph (195 km/h) sustained winds, still at Category 3 intensity.
Katrina maintained hurricane strength well into Mississippi, but weakened thereafter, finally losing hurricane strength more than 150 mi (240 km) inland near [[Jackson, Mississippi]]. It was downgraded to a tropical depression near [[Clarksville, Tennessee]], but its remnants were last distinguishable in the eastern [[Great Lakes]] region on [[August 31]], when it was absorbed by a [[Surface weather analysis#cold front|frontal boundary]]. The resulting [[extratropical]] storm moved rapidly to the northeast and affected [[Ontario]] and [[Quebec]].
==Preparations==
{{main|Preparations for Hurricane Katrina}}
===Florida===
Many living in the area were caught off guard when Katrina strengthened from a tropical storm to a hurricane in one day and struck southern [[Florida]] near the [[Miami-Dade County, Florida|Miami-Dade]]–[[Broward County, Florida|Broward]] county line. The hurricane struck between the cities of [[Aventura, Florida|Aventura]], in Miami-Dade County, and [[Hallandale, Florida|Hallandale]], in Broward County, on [[August 25]], [[2005]]. However, [[National Hurricane Center]] (NHC) forecasts had correctly predicted that Katrina would intensify to hurricane strength before landfall, and [[tropical cyclone warnings and watches|hurricane watches and warnings]] were issued 31.5 hours and 19.5 hours before landfall, respectively — only slightly less than the target thresholds of 36 and 24 hours.
Florida Governor [[Jeb Bush]] declared a state of emergency on [[August 24]] in advance of Katrina's landfall in Florida. Shelters were opened and schools closed in several counties in the southern part of the state. A number of evacuation orders were also issued, mostly voluntary, although a mandatory evacuation was ordered for at-risk housing in [[Martin County, Florida|Martin County]].Staff writer.

On the morning of [[August 26]], at 10 a.m. [[Central Daylight Time|CDT]] (1500 [[UTC]]), Katrina had strengthened to a [[Saffir-Simpson Hurricane Scale|Category 3]] storm in the Gulf of Mexico. Later that afternoon, the NHC realized that Katrina had yet to make the turn toward the Florida Panhandle and ended up revising the predicted track of the storm from the panhandle to the Mississippi coast.Spann, James.

That same evening, the NHC upgraded the section of the hurricane watch from [[Morgan City, Louisiana]] to the Alabama-Florida border to a hurricane warning, 12 hours after it was issued, and also issued a tropical storm warning for the westernmost Florida Panhandle.
On [[August 28]], as the sheer size of Katrina became clear, the NHC extended the tropical storm warning zone to cover most of the Louisiana coastline and a larger proportion of the [[Florida Panhandle]]. The [[National Weather Service]]'s New Orleans/Baton Rouge office issued a [[August 28 2005 10:11 AM CDT NOAA Bulletin|vividly-worded bulletin]] predicting that the area would be "uninhabitable for weeks" after "devastating damage" caused by Katrina, which at that time rivaled the intensity of [[Hurricane Camille]]."[http://en.wikisource.org/wiki/August_28_2005_10:11_AM_CDT_NOAA_Bulletin Urgent Weather Message]."

Voluntary and mandatory evacuations were issued for large areas of southeast [[Louisiana]] as well as coastal [[Mississippi]] and [[Alabama]]. About 1.2 million residents of the Gulf Coast were covered under a voluntary or mandatory evacuation order.
===Gulf Coast===
On [[August 26]], the state of Mississippi activated its [[United States National Guard|National Guard]] in preparation of the storm's landfall. Additionally, the state government activated its Emergency Operations Center the next day, and local governments began issuing evacuation orders. By 7:00 p.m. [[EDT]] on [[August 28]], 11 counties and eleven cities issued evacuation orders, a number which increased to 41 counties and 61 cities by the following morning. Moreover, 57 emergency shelters were established on coastal communities, with 31 additional shelters available to open if needed.{{cite book| author=[[United States Congress]] | year = [[February 19]], [[2006]] | title = A Failure of Initiative: Final Report of the Select Bipartisan Committee to Investigate the Preparation for and Response to Hurricane Katrina | publisher = [[Government Printing Office]] | location = [[Washington, DC]] | format = PDF | accessdate = 2006-04-10 |url=http://www.gpoaccess.gov/katrinareport/fullreport.pdf}}
Louisiana's hurricane evacuation plan calls for local governments in areas along and near the coast to evacuate in three phases, starting with the immediate coast 50 hours before the start of tropical storm force winds.

However, many private care-taking facilities who relied on bus companies and ambulance services for evacuation were unable to evacuate their charges. Fuel and rental cars were in short supply and many forms of public transportation had been shut down well before the storm arrived.Rulon, Malia; Scott, Katerine Hutt.

By [[August 26]], the possibility of unprecedented cataclysm was already being considered. Many of the computer models had shifted the potential path of Katrina 150 miles westward from the Florida Panhandle, putting the city of [[New Orleans, Louisiana|New Orleans]] right in the center of their track probabilities; the chances of a direct hit were forecast at 17%, with strike probability rising to 29% by [[August 28]]."[http://www.nhc.noaa.gov/archive/2005/prb/al122005.prblty.015.shtml Hurricane Katrina Probabilities Report Number 15]," & "[http://www.nhc.noaa.gov/archive/2005/prb/al122005.prblty.021.shtml Hurricane Katrina Probabilities Report Number 21]." ''[[National Hurricane Center]].'' [[August 26]], [[2005]]. Retrieved on [[2006-06-05]]. This scenario was considered a potential catastrophe because 80% of the city of New Orleans and 20% of the New Orleans metropolitan area is below sea level along [[Lake Pontchartrain]]. Since the storm surge produced by the hurricane's right-front quadrant (containing the strongest winds) was forecast to be 28 feet (8.5 m), emergency management officials in New Orleans feared that the storm surge could go over the tops of levees protecting the city, causing major flooding.Drye, Willie.

Retrieved on [[2006-06-05]]. This risk of devastation was well known; previous studies by [[Federal Emergency Management Agency of the United States|FEMA]] and the [[Army Corps of Engineers]] had warned that a direct hurricane strike on New Orleans could lead to massive flooding, which would lead to thousands of drowning deaths, as well as many more suffering from disease and dehydration as the flood waters slowly receded from the city.Bourne, Joel K.

On [[August 29]], Katrina's [[storm surge]] caused several [[breach|breaches]] in [[levees]] around [[New Orleans, Louisiana|New Orleans]]. Most of the city was subsequently [[flood]]ed, as the breached drainage and navigation canals allowed water to flow from the lake into low areas of the city and [[Saint Bernard Parish]]. Storm surge also devastated the coasts of [[Mississippi]] and [[Alabama]], making Katrina the most destructive and costliest [[natural disaster]] in the history of the [[United States]], and the deadliest hurricane since the [[1928 Okeechobee Hurricane]].

Hurricane Katrina first made landfall on [[August 25]] in [[South Florida]] where it hit as a [[Saffir-Simpson Hurricane Scale|Category 1]] hurricane, with 80 mph (130 km/h) winds. Rainfall was heavy in places and exceeded 14 inches (350 mm) in [[Homestead, Florida]], and a [[storm surge]] of 3–5 feet was measured in parts of [[Monroe County, Florida|Monroe County]]. More than 1 million customers were left without [[electricity]], and damage in Florida was estimated at between 1 and 2 billion dollars, with most of the damage coming from flooding and overturned trees. There were 11 fatalities reported in Florida as a result of Hurricane Katrina.
Most of the [[Florida Keys]] experienced tropical-storm force winds from Katrina as the storm's center passed to the north, with hurricane force winds reported in the [[Dry Tortugas]]. Rainfall was also high in the islands, with 10 inches (250 mm) falling on [[Key West, Florida|Key West]]. On [[August 26]], a strong [[Fujita scale|F1]] [[tornado]] formed from an outer rainband of Katrina and struck [[Marathon, Florida|Marathon]].

On [[August 29]] Hurricane Katrina made landfall near [[Buras, Louisiana]] with 125 mph (205 km/h) winds, as a strong Category 3 storm. However as it had only just weakened from Category 4 strength and the radius of maximum winds was large, it is possible that sustained winds of Category 4 strength briefly impacted extreme southeastern Louisiana. Although the storm surge to the east of the path of the eye in [[Mississippi]] was higher, a very significant surge affected the Louisiana coast. The height of the surge is uncertain due to a lack of data, although a tide gauge in [[Plaquemines Parish]] indicated a storm tide in excess of 14 feet (4.3 meters) and a 12 foot (3 meter) storm surge was recorded in [[Grand Isle, Louisiana|Grand Isle]].
Hurricane Katrina also brought heavy rain to Louisiana, with 8-10 inches (200-250 mm) falling on a wide swath of the eastern part of the state. In the area around [[Slidell, Louisiana|Slidell]], the rainfall was even higher, and the highest rainfall recorded in the state was approximately 15 inches (380 mm). As a result of the rainfall and storm surge the level of [[Lake Pontchartrain]] rose and caused significant flooding along its northeastern shore, affecting communities from Slidell to [[Mandeville, Louisiana|Mandeville]]. Several bridges were destroyed, including the [[I-10 Twin Span Bridge]] connecting Slidell to [[New Orleans, Louisiana|New Orleans]]. Almost 900,000 people in Louisiana lost power as a result of Hurricane Katrina.Staff Writer.

As the eye of Hurricane Katrina swept to the northeast, it subjected the city to hurricane conditions for hours. Although power failures prevented accurate measurement of wind speeds in New Orleans, there were a few measurements of hurricane-force winds. From this the NHC concluded that it is likely that much of the city experienced sustained winds of Category 1 or Category 2 strength. However, wind speeds increase with height, and therefore the winds experienced on upper floors of high rise structures were likely to have been significantly higher.
The heavy winds and storm surges from Katrina severely weakened the city's levee system, and there were reports of extensive failures of the [[levee]]s and flood walls protecting [[New Orleans, Louisiana]] and surrounding communities. The [[Mississippi River Gulf Outlet]] (MR-GO) breached its levees in approximately 20 places, flooding much of east New Orleans, most of [[Saint Bernard Parish, Louisiana|Saint Bernard Parish]] and the East Bank of [[Plaquemines Parish, Louisiana|Plaquemines Parish]]. The major levee breaches in the city included breaches at the [[17th Street Canal]] levee, the [[London Avenue Canal]], and the wide, navigable [[Industrial Canal]], which left approximately 80% of the city flooded.Murphy, Verity.

The Gulf Coast of [[Mississippi]] suffered massive damage from the impact of Hurricane Katrina on [[August 29]], leaving 238 people dead, 67 missing, and billions of dollars in damages. After making a brief initial landfall in [[Louisiana]], Katrina made its final landfall near the state line and the eyewall passed over the cities of [[Bay St. Louis, Mississippi|Bay St. Louis]] and [[Waveland, Mississippi|Waveland]] as a [[Saffir-Simpson Hurricane Scale|Category 3]] hurricane with sustained winds of 120 mph (195 km/h). Katrina's powerful right-front quadrant passed over the west and central Mississippi coast causing a powerful 27 foot (8.2 meters) [[storm surge]], which penetrated 6 miles (10 km) inland in many areas and up to 12 miles (20 km) inland along bays and rivers; in some areas, the surge reached Interstate 10.
Hurricane Katrina brought strong winds to Mississippi which caused significant tree damage throughout the state. The highest unofficial reported wind gust recorded from Katrina was one of 135 mph (215 km/h) in [[Poplarville, Mississippi|Poplarville]], in [[Pearl River County, Mississippi|Pearl River County]]. The storm also brought heavy rains with 8-10 inches (200-250 mm) falling in southwestern Mississippi and rain in excess of 4 inches (100 mm) falling throughout the majority of the state. Katrina caused eleven tornadoes in Mississippi on [[August 29]], some of which damaged trees and power lines.

One apartment complex with approximately thirty residents seeking shelter inside collapsed. More than half of the 13 casinos in the state, which were floated on barges to comply with Mississippi land-based gambling laws, were washed hundreds of yards inland by waves. A number of streets and bridges were washed away. On [[U.S. Highway 90]] along the Mississippi Gulf Coast, two major bridges were completely destroyed: the [[Bay St. Louis, Mississippi|Bay St. Louis]] - [[Pass Christian, Mississippi|Pass Christian]] bridge, and the [[Biloxi, Mississippi|Biloxi]] - [[Ocean Springs, Mississippi|Ocean Springs]] bridge. In addition, the eastbound span of the I-10 bridge over the [[Pascagoula River]] estuary was damaged. In the weeks after the storm, with the connectivity of the coastal U.S. Highway 90 shattered, traffic travelling parallel to the coast was reduced to two lanes on the remaining I-10 span.

All three coastal counties of the state were severely affected by the storm. Katrina's surge was the most extensive, as well as the highest, in the documented history of the United States; large portions of both [[Hancock County, Mississippi|Hancock]] and [[Jackson County, Mississippi|Jackson]] Counties were inundated by the storm surge, in both cases affecting most of the populated areas.{{cite web|author=[[Federal Emergency Management Agency]] | title = Mississippi Hurricane Katrina Surge Inundation and Advisory Base Flood Elevation Map Panel Overview | date = November 2005 | accessdate = 2006-07-16 | format = PDF | publisher = FEMA | url = http://www.fema.gov/pdf/hazard/flood/recoverydata/katrina/ms_overview.pdf}} Surge covered almost the entire lower half of Hancock County, destroying the coastal communities of [[Clermont Harbor, Mississippi|Clermont Harbor]] and [[Waveland, Mississippi|Waveland]], much of [[Bay St. Louis, Mississippi|Bay St. Louis]], and flowed up the Jourdan River, flooding [[Kiln, Mississippi|Kiln]]. In Harrison County, [[Pass Christian]] was completely inundated, along with a narrow strip of land to the east along the coast, which includes the cities of [[Long Beach, Mississippi|Long Beach]] and [[Gulfport, Mississippi|Gulfport]]; the flooding was more extensive in communities such as [[D'Iberville]], which borders [[Back Bay]]. [[Biloxi]], on a peninsula between the Back Bay and the coast, was particularly hard hit, especially the low-lying Point Cadet area. In Jackson County, storm surge flowed up the wide river [[estuary]], with the combined surge and freshwater flooding cutting the county in half. Remarkably, over 90% of [[Pascagoula, Mississippi|Pascagoula]], the easternmost coastal city in Mississippi, and about 75 miles east of Katrina's landfall near the Louisiana-Mississippi border, was flooded from surge at the height of the storm. Other Jackson County communities such as Porteaux Bay and Gulf Shores were destroyed, and [[St. Martin, Mississippi|St. Martin]] was hard hit; [[Ocean Springs, Mississippi|Ocean Springs]], [[Moss Point, Mississippi|Moss Point]], [[Gautier, Mississippi|Gautier]], and [[Escatawpa]] also suffered major surge damage.
Mississippi Emergency Management Agency officials also recorded deaths in [[Hinds County, Mississippi|Hinds]], [[Warren County, Mississippi|Warren]], and [[Leake County, Mississippi|Leake]] counties. Over 900,000 people through the state experienced power outages.
===Southeast United States===
Although Hurricane Katrina made landfall well to the west, [[Alabama]] and the [[Florida Panhandle]] were both affected by a significant storm surge and tropical-storm force winds. Sustained winds of 67 mph (107 km/h) were recorded in [[Mobile, Alabama]] and the storm surge there was approximately 10 feet (3 meters). The surge caused significant flooding several miles inland along [[Mobile Bay]]. Four tornadoes were also reported in [[Alabama]].
An [[oil rig]] under construction along the [[Mobile River]] broke its moorings and floated 1.5 miles (2 km) northwards before striking the [[Cochrane Bridge]] just outside Mobile. No significant damage resulted to the bridge and it was soon reopened. The damage on [[Dauphin Island]] was severe, with the surge destroying many houses and cutting a new canal through the western portion of the island. An offshore oil rig also became grounded on the island. As in Mississippi, the storm surge caused significant beach erosion along the Alabama coastline. More than 600,000 people lost power in Alabama as a result of Hurricane Katrina and two people died in a traffic accident in the state.
Along the Florida Panhandle the storm surge was typically about five feet (1.5 meters) and along the west-central Florida coast there was a minor surge of 1-2 feet (0.3-0.6 meters). In [[Pensacola, Florida]] 56 mph (90 km/h) winds were recorded on [[August 29]]. The winds caused damage to some trees and structures and there was some minor flooding in the Panhandle. There were two indirect fatalities from Katrina in [[Walton County, Florida|Walton County]] as a result of a traffic accident.
Northern and central [[Georgia (U.S. state)|Georgia]] were affected by heavy rains and strong winds from Hurricane Katrina as the storm moved inland, with more than 3 inches (75 mm) of rain falling in several areas. At least 18 tornadoes formed in Georgia on [[August 29]], the most on record in that state for one day in August. The most serious of these tornadoes was a [[Fujita scale|F2]] tornado which affected [[Heard County, Georgia|Heard County]] and [[Carroll County, Georgia|Carroll County]]. This tornado caused 3 injuries and one fatality and damaged several houses. In addition this tornado destroyed several poultry barns, killing over 140,000 chicks. The other tornadoes caused significant damages to buildings and agricultural facilities. In addition to the fatality caused by the F2 tornado, there was another fatality in a traffic accident.Westbrook, Robby; WFO Peachtree City Staff.

Katrina also had a profound impact on the environment. The storm surge caused substantial [[Coastal erosion|beach erosion]], in some cases completely devastating coastal areas. In [[Dauphin Island]], approximately 150 [[km]] (90 mi) to the east of the point where the hurricane made landfall, the sand that comprised the [[barrier island]] was transported across the island into the [[Mississippi Sound]], pushing the island towards land.{{cite web | author = [[United States Geological Survey]] | date = [[September 14]], [[2005]] | url = http://coastal.er.usgs.gov/hurricanes/katrina/lidar/dauphin-island.html | title = Daupin Island - Pre- and Post-Storm 3D Topography | work = Hurricane Katrina Impact Studies | publisher = [[USGS]] | accessdate = 2006-06-05}} The storm surge and waves from Katrina also obliterated the [[Chandeleur Islands]], which had been affected by [[Hurricane Ivan]] the previous year.{{cite web | author = [[United States Geological Survey]] | date = [[September 14]], [[2005]] | url = http://coastal.er.usgs.gov/hurricanes/katrina/photo-comparisons/chandeleur.html | title = Before and After Photo Comparisons: Chandeleur Islands | work = Hurricane Katrina Impact Studies | publisher = [[USGS]] | accessdate = 2006-06-05}}

===Non-government organization response===
The [[American Red Cross]], [[Salvation Army]], [[Common Ground Collective]], [[Emergency Communities]], and many other charitable organizations provided housing, food, and water to the victims of the storm. These organizations also provided an infrastructure for shelters throughout Louisiana and other states that held thousands of evacuees. They were not, however, allowed into New Orleans proper by the National Guard for several days after the storm, due to safety concerns. These organizations raised $4.25 billion in donations by the public, with the Red Cross receiving over half of the donations.{{ cite web | author = Staff writer | publisher= [[Charity Navigator]] | title = Where Did The Money Go? | date = 2006 | accessdate = 2006-08-05 | work = Hurricane Katrina: One Year Later | url = http://www.charitynavigator.org/index.cfm/bay/katrina.main.htm}}

===Analysis of New Orleans levee failures===
{{main|Levee failures in Greater New Orleans, 2005}}
[[New Orleans, Louisiana|New Orleans]]' levee failures were found to be primarily the result of system design flaws, combined with the lack of adequate maintenance. Those responsible for the conception, design, construction, and maintenance of the region's flood-control system apparently failed to pay sufficient attention to public safety, according to an investigation by the [[National Science Foundation]].Myers, Lisa. "[http://www.msnbc.msn.com/id/9532037/ New Orleans levee reported weak in 1990s]." ''[[MSNBC]].'' [[September 30]], [[2005]]. Retrieved on [[2006-06-05]].
According to new modeling and field observations by a team from [[Louisiana State University]], the [[Mississippi River Gulf Outlet]] (MRGO), a 200-meter wide canal designed to provide a shortcut from New Orleans to the Gulf of Mexico, helped provide a funnel for the storm surge, making it 20% higher and 100%-200% faster as it crashed into the city. St. Bernard Parish, one of the more devastated areas, lies just south of the MRGO. The [[Army Corps of Engineers]] disputes this causality and maintains Katrina would have overwhelmed the levees with or without the contributing effect of the MRGO.Warrick, Joby; Grunwald, Michael. "[http://www.washingtonpost.com/wp-dyn/content/article/2005/10/23/AR2005102301200_pf.html Investigators Link Levee Failures to Design Flaws]." ''[[Washington Post]].'' [[October 24]], [[2005]]. Retrieved on [[2006-06-05]].
On [[April 5]], [[2006]], months after independent investigators had demonstrated that levee failures were not due to natural forces beyond intended design strength, Lt. Gen. Carl Strock testified before the United States Senate Subcommittee on Energy and Water that "We have now concluded we had problems with the design of the structure." He also testified that the U.S. Army Corps of Engineers did not know of this mechanism of failure prior to [[August 29]], [[2005]]. The claim of ignorance is refuted, however, by the National Science Foundation investigators hired by the Army Corps of Engineers, who point to a 1986 study by the Corps itself that such separations were possible in the I-wall design.{{cite news| title = Corps chief admits to 'design failure' | author = Walsh, Bill | publisher = [[Times Picayune]] | date = [[April 06]], [[2006]] | accessdate=2006-04-09 | url = http://www.nola.com/news/t-p/frontpage/index.ssf?/base/news-5/1144306231230500.xml}}
===Criticism of government response===
{{main|Criticism of government response to Hurricane Katrina}}
[[Image:Kanyebush.jpg|250px|thumb|right|Rapper [[Kanye West]] accused President Bush of racism during a Hurricane Katrina [[benefit concert]], ''[[A Concert for Hurricane Relief]]''.]]
The criticisms of the government's response to Hurricane Katrina primarily consisted of condemnations of [[Administrative incompetence|mismanagement]] and lack of [[leadership]] in the relief efforts in response to the storm and its aftermath. More specifically, the criticism focused on the delayed response to the flooding of [[New Orleans, Louisiana|New Orleans]], and the subsequent state of chaos in the Crescent City.Thevenot, Brian; Russell, Gordon. "[http://seattletimes.nwsource.com/html/nationworld/2002520986_katmyth26.html Reports of anarchy at Superdome overstated]." ''[[Seattle Times]].'' [[September 26]], [[2005]]. Retrieved on [[2006-06-05]]. The neologism ''Katrinagate'' was coined to refer to this controversy, and was even a runner-up for "2005 word of the year."Clark, Heather. "[http://abcnews.go.com/US/wireStory?id=1480616 Linguists Vote 'Truthiness' Word of 2005]." ''[[ABC News]].'' [[January 6]], [[2006]]. Retrieved on [[July 18]], [[2006]].
Within days of Katrina's [[August 29]], [[2005]] landfall, public debate arose about the local, state and federal governments' role in the [[Preparations for Hurricane Katrina|preparations]] for and response to the hurricane. [[Criticism]] was prompted largely by televised images of visibly shaken and frustrated political leaders and of residents who remained in New Orleans without [[drinking water|water]], [[food]] or [[shelter]]. The deaths of several citizens by [[thirst]], [[exhaustion]], and [[violence]] days after the storm itself had passed also fueled the criticism, as did the treatment of people who had been evacuated to facilities such as the [[Superdome]]. Others alleged that [[race]], [[social class|class]], and other factors could have contributed to delays in government response. The percentage of black victims among storm-related deaths (49%){{cite web | title = Updated Number of Deceased Victims Recovered Following Hurricane Katrina | date = [[December 9]], [[2005]] | accessdate = 2006-08-01 | publisher = Louisiana Department of Health and Hospitals | url = http://www.dhh.state.la.us/news.asp?Detail=758}} was below their proportion in the area's population (approx. 60%).
The government was accused of making things worse, instead of making things better—perhaps even deliberately—by preventing help by others while delaying its own response. In accordance with federal law, President [[George W. Bush]] directed the [[Secretary of Homeland Security|Secretary of the Department of Homeland Security]], [[Michael Chertoff]], to coordinate the Federal response. Chertoff designated [[Michael D. Brown]], head of the [[Federal Emergency Management Agency]], 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 initially came under harsh criticism for what some perceived as a lack of planning and coordination. (Some reports indicated that the relief effort was intentionally hindered by FEMA{{cite web | author = Mike Whitney | title = The Siege of New Orleans | date = [[September 8]], [[2005]] | accessdate = 2006-07-19 | publisher = Information Clearing House | url = http://www.informationclearinghouse.info/article10182.htm}}). Eight days later, Brown was recalled to Washington and Coast Guard Vice Admiral [[Thad W. Allen]] replaced him as chief of hurricane relief operations.Meserve, Jeanne; Barrett, Ted. "[http://www.cnn.com/2005/POLITICS/09/09/katrina.washington/index.html Admiral takes over Katrina relief]." ''[[CNN]].'' [[September 9]], [[2005]]. Retrieved on [[2006-06-05]].

Subsequently, criticism from politicians, activists, pundits and journalists of all stripes has been directed at the local, state and federal governments headed by Mayor [[Ray Nagin]] of New Orleans and Louisiana Governor [[Kathleen Blanco]]. Nagin and Blanco were criticized for failing to implement New Orleans' evacuation plan and for ordering residents to a shelter of last resort without any provisions for food, water, security, or sanitary conditions. Perhaps the most important criticism of Nagin is that he delayed his [[emergency evacuation]] order until 19 hours before landfall, which led to hundreds of deaths of people who (by that time) could not find any way out of the city.
The destruction wrought by Hurricane Katrina has raised other, more general public policy issues about [[emergency management]], [[environmental policy]], [[poverty]], and [[unemployment]]. The discussion of both the immediate response and of the broader public policy issues may affect [[elections]] and [[legislation]] enacted at various [[Executive (government)|levels of government]]. The storm's devastation also caused a Congressional investigation, which found that FEMA and the Red Cross "did not have a logistics capacity sophisticated enough to fully support the massive number of Gulf coast victims." Additionally, it placed responsibility for the disaster on all three levels of government.
An [[ABC News]] [[Opinion poll|Poll]] conducted on [[September 2]], showed slightly more blame is being directed at state and local governments (75 percent) than at the Federal government (67 percent), with 44 percent blaming President Bush's leadership directly.Langer, Gary.

A later [[CNN]]/[[USAToday|USATODAY]]/[[Gallup|GALLUP]] [[Opinion poll|poll]] showed that respondents disagreed widely on who is to blame for the problems in the city following the hurricane -- 13 percent said Bush, 18% said federal agencies, 25% blamed state or local officials and 38% said no one was to blame.Staff Writer.

===Media involvement===

[[Image:Geraldo-Rivera-Katrina-Aftermath-FNC.jpg|thumb|250px|right|[[Geraldo Rivera]] reporting from the New Orleans Convention Center on [[September 2]], [[2005]].]]
Many representatives of the [[news media]] reporting on the aftermath of Hurricane Katrina became directly involved in the unfolding events, instead of simply reporting. Due to the loss of most means of communication, such as land-based and cellular telephone systems, field reporters in many cases became conduits for information between victims and authorities.
The authorities, who monitored local and network news broadcasts, as well as internet sites, would then attempt to coordinate rescue efforts based on the reports. One illustration was when [[Geraldo Rivera]] of [[Fox News]] tearfully pleaded for authorities to either send help or evacuate the thousands of evacuees stranded at the [[Ernest N. Morial Convention Center]]."[http://www.ifilm.com/ifilmdetail/2678976 Geraldo Rivera & Shepard Smith Unleashed]." -- ''Video.'' 2005. Retrieved on [[2006-06-05]].
The storm also brought a dramatic rise in the role of [[Website|Internet sites]] - especially [[blogging]] and community journalism. One example was the effort of ''NOLA.com'', the web affiliate of the [[New Orleans Times-Picayune]], which was awarded the Breaking News [[Pulitzer Prize]],{{cite web | author = The Pulitzer Board | title = 2006 Pulitzer Prize Winners - Breaking News Reporting | date = 2006 | accessdate = 2006-08-02 | url = http://www.pulitzer.org/year/2006/breaking-news-reporting/}} and shared the Public Service Pulitzer with the Biloxi-based [[The Sun Herald|Sun Herald]].{{cite web | author = The Pulitzer Board | title = 2006 Pulitzer Prize Winners - Public Service | date = 2006 | accessdate = 2006-08-02 | url = http://www.pulitzer.org/year/2006/public-service/}} The newspaper's coverage was carried for days only on NOLA's blogs, as the newspaper lost its presses and evacuated its building as water rose around it on August 30. The site became an international focal point for news by local media, and also became a vital link for rescue operations and later for reuniting scattered residents, as it accepted and posted thousands of individual pleas for rescue on its blogs and forums. NOLA was monitored constantly by an array of rescue teams - from individuals to the Coast Guard - which used information in rescue efforts. Much of this information was relayed from trapped victims via the SMS functions of their cell phones, to friends and relatives outside the area, who then relayed the information back to NOLA.com. The aggregation of community journalism, user photos and the use of the internet site as a collaborative response to the storm attracted international attention, and was called a watershed moment in journalism.{{cite web | author = Mark Glaser | title = NOLA.com blogs and forums help save lives after Katrina | date = [[September 13]], [[2005]] | publisher = Online Journalism Review | accessdate = 2006-08-02 | url = http://www.ojr.org/ojr/stories/050913glaser/}} In the wake of these online-only efforts, the Pulitzer Committee for the first time opened all its categories to online entries.{{cite web | author = [[Paul Steiger]] | title = Remarks at Pulitzer Prize luncheon | date = [[May 22]], [[2006]] | accessdate = 2006-08-02 | publisher = The Pulitzer Board | url = http://www.pulitzer.org/resources/steigerspeech.html}}
As the U.S. military and rescue services regained control over the city, there were restrictions on the activity of the media. On [[September 9]], the military leader of the relief effort announced that reporters would have "zero access" to efforts to recover bodies in New Orleans. Immediately following this announcement, [[CNN]] filed a [[lawsuit]] and obtained a temporary [[restraining order]] against the ban. The next day the government backed down and reversed the ban.Staff Writer. "[http://edition.cnn.com/2005/LAW/09/10/katrina.media/ U.S. won't ban media from New Orleans searches]." ''[[CNN]].''
