HURRICANE KATRINA SUMMARY
Hurricane Katrina is the deadliest, costliest and most destructive Atlantic Tropical cyclone of the 2005 Atlantic hurricane season compared to all other natural disasters in the history of the U.S. it is the 7th most in tense Atlantic hurricane ever recorded, part of the 2005 season, that included 3 of the 6 most intense Atlantic hurricanes ever documented.
At least 1,833 people died in the hurricane and subsequent floods, making it the deadliest since 1928 Okeechobee hurricane; total property damage was estimated at $108 billion roughly 4 times the damage brought by hurricane Andrew in 1992.
Hurricane Katrina formed over the Bahamas on August 23, 2005 and crossed Southern Florida as a moderate category or hurricane causing some deaths and flooding there before the hurricane strengthened to a category 5 hurricane over the warm Gulf water.
It however weakened before making its second landfall as a category 3 hurricane on the morning of Monday, August 29th in South East Louisiana causing severe destruction along the Gulf coast from Central Florida to Texas, due to the storm surge.
Most significant number of deaths occurred in New Orleans, Louisiana, due to flooding as the Levee system failed, after the storm had moved inland. 80% of the city and large tracts of neighboring parishes became flooded and it stayed on for weeks.
The worst property damage occurred in Coastal areas such as all Mississippi beachfront towns, which were over 90% flooded in hours, as boats rammed into buildings pushing cars and houses inland, with waters reaching 6-12 miles (10-19 km) from the beach.
The failure to protect the hurricane surge in New Orleans is considered the worst civil engineering disaster in U.S. history. This prompted a law suit against the U.S. Army Corps of Engineers (USACE). The National Weather Service is commended for providing information prior to the occurrence.
