On June 5, Tropical Storm Allison rolled into Southeast Texas. There its movement stalled and the storm floated above the area, dumping as much as three feet of rain in six days -- causing one of the worst floods in Texas history. Reports estimate the storm may have caused up to $7 billion in damages. Twenty-two people were killed by the storm before it moved north and eventually soaked Philadelphia.

There have been more than 20,000 flood insurance claims in the state of Texas, amounting to nearly $350 million.
