Thursday, September 10th, 2026 — Hurricane Helene made landfall in Florida’s Big Bend on the night of September 26, 2024, as a Category 4 storm. The worst of it happened the next morning, three hundred miles inland and several thousand feet up. The southern Appalachians had already absorbed heavy rain from a stalled front in the days before the storm arrived. Helene’s remnants dropped another one to two feet on top of that. Rivers in western North Carolina rose past every recorded crest. The French Broad in Asheville exceeded its 1916 record. Whole sections of Chimney Rock and Swannanoa were carried downstream. More than 100 people died in North Carolina alone.
When the adjusters arrived, they found a region with almost no flood insurance. In Buncombe County, home to Asheville, roughly one percent of households carried an NFIP policy. Most of the homes destroyed sat outside any mapped flood zone, because the maps described the rivers’ historical behavior and the rivers had never behaved like this. Thousands of homeowners with intact homeowners policies learned, in the space of a single conversation, that the policy they had paid on for years excluded the thing that had happened to them.
Helene was extreme, and it was also part of a pattern. Hurricane Harvey dropped more than 60 inches on parts of southeast Texas in 2017 and flooded roughly 200,000 homes, most of them outside the mapped floodplain and most of them uninsured for flood. The remnants of Ida in 2021 killed people in basement apartments in Queens and flooded New Jersey neighborhoods that had never flooded. Vermont’s capital flooded in July 2023 and again in July 2024. Extreme rainfall is producing flood losses in places whose exposure was never priced, mapped, or insured, and adjusters are the ones sent to explain it…
