Record tornado activity expands insurance risk into more populated areas
Illinois recorded 220 confirmed tornadoes through the end of July, and Verisk data show losses are rising faster than tornado counts, with average estimated reconstruction value 72.0% above 2022.
Insurance Journal reports that even as the peak of tornado season fades, the eastward shift of severe storm risk is likely to keep raising insurance concerns as tornado exposure grows in more populated areas. According to the report, the increase in claims and risk is not explained by higher U.S. tornado counts, but by greater exposure where storms hit. It cites record tornado activity in Illinois, Indiana, and Wisconsin this year, including Illinois leading all states with 220 confirmed tornadoes through the end of July.
The article attributes the “Tornado Alley” shift beyond places such as Texas, Oklahoma, and Kansas to a warming climate that helps move warmer, more-humid air farther north and east. It adds that Illinois has seen a third distinct spike in five years, with year volume already exceeding 2024 and 2025 combined.
The report also highlights how losses are worsening even as national tornado claim volume declines. It says tornado volume peaked in 2023 and has fallen each year since, but the average estimated reconstruction value is up every year and stands 72.0% above 2022, with severity rising since 2022.
Insurance Journal quotes Verisk Weather Solutions vice president Tory Farney saying insurer concerns center on the greater population as risk shifts east, and notes the trend is measurable, though whether patterns will persist or revert remains uncertain.
