Hurricane Katrina (2005)

Hurricane Katrina occurred between 23 and 30 August 2005. It first caused fatalities and damage in southern Florida as a category 1 hurricane. After reaching category 5 intensity over the central Gulf of Mexico, Katrina weakened to category 3 before making landfall on the northern Gulf coast. It was the costliest and one of the five deadliest hurricanes to ever strike the United States. Inundation up to 24-28 feet above ground level was observed along large portions of the Mississippi, Louisiana, Alabama, and Florida coast. The strongest sustained wind measured from a fixed location at the surface was 76 knots. There was a total of 1833 fatalities in the United States with about $108 billion property damage [NOAA, 2005]1.

Atlantic Hurricane Season of 2005 The Hurricane Season summaries include descriptions of named storms along with pertinent meteorological data and satellite imagery. NOAA – National Hurricane Center
Service Assessment: Hurricane Katrina August 23-31, 2005 The NWS conducts service assessments of significant weather-related events that result in at least one fatality, numerous injuries requiring hospitalization, extensive property damage, widespread media interest, or an unusual level of scrutiny of NWS operations by the media, EMs, or elected officials. The intent of service assessments is to thoroughly evaluate the NWS performance and ensure the effectiveness of NWS products and services in meeting its mission. NOAA - National Weather Service
Mapping and Visualization of Storm-Surge Dynamics for Hurricane Katrina and Hurricane Rita This report uses some of the same data sources as the FEMA products but extends the storm-surge mapping to larger areas and provides additional derived storm-surge datasets through different presentation methods.
