'''Hurricane Katrina''' was the costliest and one of the deadliest ]s in the history of the ]. It was the sixth-strongest ] ever recorded and the third-strongest landfalling U.S. hurricane on record.

===South Florida and Cuba===
] following Hurricane Katrina.]]

Hurricane Katrina first made landfall on ] in ] where it hit as a ] hurricane, with 80&nbsp;mph (130&nbsp;km/h) winds. Rainfall was heavy in places and exceeded 14&nbsp;inches (350&nbsp;mm) in ],<ref name="KatrinaTCR"/> and a ] of 3–5&nbsp;feet was measured in parts of ].<ref name="katreport"/> More than 1 million customers were left without ], 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.<ref name="KatrinaTCR"/>

Most of the ] experienced tropical-storm force winds from Katrina as the storm's center passed to the north, with hurricane force winds reported in the ].

According to Cuban television reports the coastal city of Surgidero de Batabano was 90% underwater.<ref name="Cuba damage">Staff Writer. "."</ref>

===Louisiana===

On ] Hurricane Katrina made landfall near ] with 125&nbsp;mph (205&nbsp;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 ] was higher, a very significant surge affected the Louisiana coast. The height of the surge is uncertain because of a lack of data, although a tide gauge in ] indicated a storm tide in excess of 14&nbsp;feet (4.3&nbsp;m) and a 12&nbsp;foot (3&nbsp;m) storm surge was recorded in ].<ref name="KatrinaTCR"/>

Hurricane Katrina also brought heavy rain to Louisiana, with 8-10&nbsp;inches (200-250&nbsp;mm) falling on a wide swath of the eastern part of the state. In the area around ], the rainfall was even higher, and the highest rainfall recorded in the state was approximately 15&nbsp;inches (380&nbsp;mm). As a result of the rainfall and storm surge the level of ] rose and caused significant flooding along its northeastern shore, affecting communities from Slidell to ].

] and surrounding area of northwest New Orleans and Metairie, Louisiana]]
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.<ref name="KatrinaTCR"/>

The heavy winds and storm surges from Katrina severely weakened the city's levee system, and there were reports of extensive failures of the ]s and flood walls protecting ] and surrounding communities. The ] (MR-GO) breached its levees in approximately 20 places, flooding much of east New Orleans, most of ] and the East Bank of ].

Sustained winds of 67&nbsp;mph (107&nbsp;km/h) were recorded in ] and the storm surge there was approximately 10&nbsp;feet (3&nbsp;meters).

===Analysis of New Orleans levee failures===
{{main|Levee failures in Greater New Orleans, 2005}}
]' 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 ].<ref>Myers, Lisa. "." ''].'' ], ]. Retrieved on ].</ref>

According to new modeling and field observations by a team from ], the ] (MRGO), a 200-meter (660&nbsp;ft) 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 ] disputes this causality and maintains Katrina would have overwhelmed the levees with or without the contributing effect of the MRGO.<ref>Warrick, Joby; Grunwald, Michael. "." ''].'' ], ].

On ], ], months after independent investigators had demonstrated that levee failures were not caused by natural forces beyond intended design strength, Lieutenant General 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 ], ]. 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.<ref>{{cite news| title = Corps chief admits to 'design failure' | author = Walsh, Bill | publisher = ] | date = ], ] | accessdate=2006-04-09 | url = http://www.nola.com/news/t-p/frontpage/index.ssf?/base/news-5/1144306231230500.xml}}</ref>

Additionally, various ] began floating around that the levees were in fact deliberately demolished. The most commonly cited culprit in these conspiracy theories is the ] Biosphere program, in an attempt to "re-wild" the region. These theories arose when several New Orleans residents described hearing "explosions" coming from the levees before the floodwaters rushed in, and by a National Guard worker who claims he was sworn to secrecy upon finding explosives residue at the site of the break. <ref> http://www.whatreallyhappened.com/orleans_levees.html</ref>
