Cotality, a global provider of property information, analytics, and technology-enabled data solutions, has estimated insured losses from Hurricane Isaias’ wind and storm surge at USD 2 billion to USD 3 billion, with the bulk of losses expected in the Florida Panhandle and southern Alabama.
Hurricane Isaias made landfall near Destin, Florida, on 9 October, 2026, as a Category 2 hurricane with maximum sustained winds of 105 mph, with the centre about 40 miles east of Pensacola and 50 miles west-northwest of Panama City.
The hurricane had peaked as a Category 3 major hurricane over the Gulf earlier in the day before increasing wind shear weakened it on approach.
Cotality confirmed that a station near Santa Rosa Sound recorded sustained winds of 91 mph and a gust of 116 mph, while Pensacola recorded sustained winds of 63 mph and a gust of 100 mph.
According to forecasters predicted the peak storm surge of 6 to 9 feet from the Alabama-Florida border to Grayton Beach and 4 to 7 feet from Grayton Beach to Indian Pass. East of landfall, a NOAA water-level gauge at Panama City Beach measured water 5.6 feet above mean higher high water, which approximates inundation at that location.
By 11 October, Isaias weakened quickly after landfall and became a post-tropical cyclone over Alabama; the remnant low was about 180 miles northeast of Nashville, Tennessee, with winds near 25 mph.
Power outages were widespread, with hundreds of thousands of people losing power across the Florida Panhandle and southern Alabama, including roughly 448,000 in Florida, according to Florida Governor Ron DeSantis.
Initially, Cotality estimated that Hurricane Isaias would sit at a moderate or greater risk of storm surge damage, representing about USD 65.2 billion in reconstruction cost value (RCV). Additionally, wind exposure would cause damage to about 777,000 homes in the eight counties, with about USD 241.6 billion in RCV.
Cotality said that surge losses will fall mainly on the National Flood Insurance Program (NFIP) and private flood carriers. Wind damage and outage-related claims will fall on homeowners policies.
Moody’s has stated that Hurricane Isaias will deliver a modest regional economic shock, with an estimated USD 1-2 billion in lost economic output.
Meanwhile, Accuweather said that it estimated that Isaias will cause an estimated USD 16-20 billion in total damage and economic loss across the Gulf and the eastern United States.
Lastly, Euler ILS Partners, a specialist ILS investment manager, has put the initial industry loss estimate at between USD 2-4 billion.
