Facts about Hurricane Katrina
The following fact sheet contains interesting facts and information on Hurricane Katrina.

The great storm began on August 23, 2005 as the temperature of the ocean off the coast of the Bahamas hovered around 85 degrees Fahrenheit in an area of low pressure consisting of warm weather, storms and rain - ideal conditions for a hurricane to form.

Hurricane Katrina was formed as winds hit 39 mph. On August 25, 2005 The weather phenomenon reached a Category 1 status when it briefly hit the Florida peninsula,  with 80 mph winds. A Category 1 is described as having very dangerous winds likely to produce some damage.

Katrina then spun out into the Gulf of Mexico where it gained in intensity reaching a Category 5 hurricane by August 27, 2005 with winds of 160 mph and a storm surge over 20 feet high.

As Katrina left the Gulf and made landfall. Without its water vapor "fuel" its intensity decreased and when it hit Louisiana it was classed as a Category 4 hurricane, with sustained winds of 127 miles per hour. A Category 4 hurricane results in 'Catastrophic damage' which is testified in its effects on New Orleans.

New Orleans is a large Louisiana port on the Mississippi River, near the Gulf of Mexico with a population of nearly 350,000 people.

20 hours before the storm struck New Orleans, Mayor Ray Nagin issued the first ever mandatory evacuation order of the city. Although many New Orleanians were evacuated, it was a slow process and the poorest and most vulnerable people were left behind.

New Orleans was devastated. Many parts of New Orleans have an elevation that is lower than sea level. Levees and Floodwalls catastrophically failed and 80% of the was city flooded and power was lost. (The Levees are water barriers built to prevent flooding).

Many thousands of residents who had remained in the city were rescued. 20,000 desperate people made their way to a "shelter of last resort" at the Louisiana Superdome and others to the New Orleans Morial Convention Center.

Flooding: The main tourist centers and business district were relatively undamaged by the flooding. It was the residential areas that suffered the most. Some areas were deluged with one foot of flooding while other areas were submerged by more than 10 feet of water. 

Loss of Homes: In New Orleans 70% of all homes, over 134,000 housing units,  suffered damage as helpless residents were made homless. FEMA trailers later housed at least 114,000 families.

Transport: Transport links were severely effected as the Louis Armstrong New Orleans International Airport was closed and most roads in New Orleans were flooded and impassable.

Power Outages: 42% of homes in New Orlesns were without power in the aftermath of the great storm

Drinking water: Drinking water was also unavailable in New Orleans due to a broken water main that served the city.

Health Risks: Concerns grew regarding health risks following the flooding as people began to suffer from food poisoning and dehydration.  The growing contamination of food and drinking water supplies in New Orleans could potentially spread diseases such as cholera, tuberculosis and typhoid fever. There was also a risk from mosquito-borne diseases such as malaria and yellow fever.

Environmental Impact: The cleanup effort involved pumping the flood waters that covered New Orleans into Lake Pontchartrain. The flood waters contained a mixture of oil, raw sewage, bacteria, pesticides and toxic chemicals effecting the fish in the lake.

Hurricane Katrina weakened to a Category 3 status as it hit near Buras-Triumph, Louisiana and Mississippi with sustained winds of 125 mph. The death toll in Mississippi was 238.

The great storm was downgraded from a hurricane status to a 'tropical depression' as it reached Clarksville, Tennessee. A tropical depression produces maximum sustained winds below 39 mph.

The effects of the 'tropical depression' continued across  Alabama, Georgia, Kentucky and Ohio. There were 2 deaths in Alabama, 2 deaths in Georgia, 1 death in Kentucky and 2 deaths in Ohio.

The storm surge from Mobile Bay led to the inundation of downtown Mobile, Alabama resulting in a dusk-to-dawn curfew for the City. A storm surge is an abnormal rise of water resulting in a change in sea level generated by a storm. A storm surge can lead to extensive flooding and are dangerous for people living in many coastal areas.
