¶ … management to Hurricane Katrina Hurricane Katrina 11th named tropical storm by scientists, fourth hurricane, third major hurricane and first category 5 hurricane of the 2005 Atlantic hurricane season. On the day of August 5, 2005 hurricane Katrina made a land fall as a category 1 hurricane north of Miami, Florida, as a category 3 storm on August 29 along the central gulf coast near Buras-triumph then Louisiana. The storm surge of Katrina later destroyed the levee system that protected New Orleans from Lake Pontchartrain and the Mississippi river. (Stewart & Stacy, 2005)

As a consequence the city was subsequently flooded mainly by water from the lake. The coast of Mississippi and Alabama were heavily damaged resulting to Katrina being the most destructive and costly disaster in the history of the U.S.A., the damage estimated at $100 billion.

In the Gulf of Mexico approaching the morning of the 26 0f August Katrina had gained strength to a Category 3 storm. On realizing later that afternoon that Katrina had yet to make the turn towards Florida panhandle, the National Hurricane Center (NHC) ended up revising the predicted track of the storm from the panhandle to the Mississippi coast. The hurricane watch was issued by NHC for southeastern Louisiana, including the New Orleans area . That afternoon the NHC extended the watch to cover the Mississippi and Alabama...

coast guards began preparing and putting in position resources in a ring around the expected impact zone. On August 27, the coast guard moved its personnel out of the New Orleans region in readiness for the mandatory evacuation.
Many air crews most of whom had lost their homes during the catastrophe began a round the clock rescue effort in new Orleans, and along the Mississippi and Alabama coastlines, by the afternoon of August 29, all aircraft were returning towards the Gulf of Mexico by the afternoon of August 29. (Stephen Barr, 2005)

By August 26, the possibility of unexpected and highly volatile cataclysm was already being considered. The computer models had shifted the potential path of Katrina 150 miles (240 km) westward from the Florida Panhandle, putting the city of New Orleans directly in the center of their track probabilities raising the chances of a direct to 17% as were the forecast, with strike probability rising to 29% by August 28. This scenario was considered a potential catastrophe since some parts of New Orleans and the metro area are below sea level.

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…
