As Hurricane Sally slowly moves over the Gulf Coast in the next few days, historical flooding is predicted from rainfall for parts of Alabama, Georgia, Mississippi, Louisiana, Florida and the Carolinas.
National Weather Service published a map of areas in Gulf Coast states most at risk for flash floods. Triple-I estimated the percentage of properties in these counties that are covered by flood insurance and found that purchase rates are remarkably low in some areas. In Taylor County, GA for example, just 0.09 percent of properties are insured against flooding.
Standard homeowners and renters insurance policies do not cover flooding. The National Flood Insurance Program (NFIP) and a growing number of private companies sell the coverage. However, NFIP policies purchased now would take 30 days to take effect. Private companies have shorter waiting periods, about 14 days.
