Natural Disasters are naturally occurring events which can directly or indirectly cause severe threats to a publics well-being. Because they are naturally occurring , natural disasters create an ever present threat which can only be dealt with through proper planning.
Hurricanes occur because their source of energy is water vapor , which is evaporated from the ocean surface . It releases the latent heat of condensation when it condenses to form clouds and rain , warming the surrounding air. The heat was absorbed by the water vapor when it was evaporated from the warm ocean surface, so the warm ocean cools down ; a hurricane is like the Earth's air condition that helps to cool the Earth.
Hurricane Katrina formed over the Bahamas on August 23, 2005 and crossed southern Florida as a moderate Category 1 hurricane , causing some deaths and flooding there before strengthening rapidly in the Gulf of Mexico The storm weakened before making its second landfall as a Category 3 storm on the morning of Monday, August 29 in southeast Louisiana . The storm rapidly intensified after entering the Gulf, growing from a Category 3 hurricane to a Category 5 hurricane in just nine hours . This rapid growth was due to the storm's movement over the "unusually warm" waters of the Loop current, which increased wind speeds. On Saturday, August 27, the storm reached Category 3 intensity on the Saffir-Simpson Hurricane Scale, becoming the third MAJOR hurricane of the season.
It left people homeless , stranded and unemployed . The effects on the people were devastating. Food and fresh water was so scarce that people were forced to the streets, which resulted in violence, racial aggression, theft and murder .

Evelyn Turner cried alongside the body of her common-law husband, Xavier Bowie, after he died in New Orleans. Bowie and Turner had decided to ride out Hurricane Katrina when they could not find a way to leave the city. Bowie, who had lung cancer, died when he ran out of oxygen Tuesday afternoon.
In addition to the deaths, shattered lives, and billions of dollars in property damage that Hurricane Katrina caused, the hurricane left a long-lasting legacy of environmental damage and serious threats to public health.
The political impacts of Hurricane Katrina have been largely caused by the negligence and lack of leadership in the relief effort. Criticism was prompted largely by televised images of New Orleans residents who remained stranded without water, food or shelter ; and the deaths of several citizens of thirst, exhaustion, and violence days after the storm itself had passed.
The effects of Hurricane Katrina in New Orleans were long-lasting . Reconstruction of New Orleans has been ongoing ever since the hurricane struck the city. By Monday, September 5, 2005 power began to be restored to buildings in the central business district of New Orleans on a priority basis. Relief agencies have helped many returnees. The Red Cross made a belated significant entry into the city in mid-September, and by the start of October had a number of relief centers set up around the city .
