Irene Joins Top Ten Most Costly U.S. Hurricanes

A new ranking of the top ten most costly hurricanes just released by the Insurance Information Institute (I.I.I.) puts 2011’s Hurricane Irene in tenth place, replacing 2004’s Hurricane Jeanne.

Hurricane Irene made landfall near Cape Lookout, North Carolina, on August 27, 2011 as a Category 1 storm and a second landfall in New Jersey and New York City as a tropical storm the next day.

In all, Irene affected 14 states and resulted in $4.3 billion in insured damages, according to the Property Claim Services unit of ISO, and was directly responsible for 41 fatalities.

The insured damages tally does not include flood damage that is covered by the federally administered National Flood Insurance Program (NFIP).

Irene caused major flooding as it headed northward up the Atlantic seaboard. The I.I.I. notes that Irene caused catastrophic flooding in New York and New England, especially Vermont.
