Florida Keys homeowners have filed nearly 15 percent of the statewide Hurricane Irma windstorm claims filed with Citizens Property Insurance Corp., a state-backed agency. "Irma, which hit the Florida Keys on Sept. 10 as a Category 4 hurricane, is expected to produce up to 70,000 claims [statewide] and $1.2 billion in damages to Citizens policyholders," the insurer of last resort reported Wednesday. As of Wednesday, Keys clients had filed 9,063 claims for windstorm coverage, part of the 62,412 in wind-damage claims throughout Florida.
