In the Tampa Bay area, Polk County had the highest number of claims, with more than 10,001, a map from insurance regulators indicated. Insurance regulators declined to provide specific numbers for each county. Hillsborough and Pinellas counties had between 5,001 and 10,000 claims each; Pasco, Manatee and Sarasota counties had between 2,501 and 5,000 claims each, and Hernando County had between 1,001 and 2,500 claims, the map indicated.
It’s still unclear where Irma stands among costliest hurricanes in the United States. A list from the Insurance Information Institute shows Hurricane Katrina in 2005 had the highest level of insured losses — $49.8 billion in 2016 dollars — followed by Hurricane Andrew in 1992, with $24.5 billion in insured losses in 2016 dollars.
