What happened
Hurricane Katrina will likely go down as the worst and costliest natural disaster in United States history. The amount of destruction, the cost of damaged property/agriculture and the large loss of life across the affected region has been overwhelming. Catastrophic damage was widespread across a large portion of the Gulf Coast region. The devastation was not only confined to the coastal region, widespread and significant damage occurred well inland up to the Hattiesburg area and northward past Interstate 20. This hurricane has changed life as we know it across the Gulf Coast region which will take many years to return to normal.Hurricane Katrina was a very large and powerful storm which set several unfortunate records. This storm began as Tropical Depression 12 during the late afternoon and evening of August 23rd. The storm slowly moved northwest, became more organized, and was upgraded to Tropical Storm during the late morning of August 24th as it moved across the Central Bahamas. The Tropical Storm continued to become better organized as it moved slowly west toward Southern Florida. Katrina became a Category 1 Hurricane late in the afternoon on August 25th just before moving...
