Severe weather in the second half of April caused significant property damage across several U.S. states, with insured losses expected to reach hundreds of millions of dollars, according to Aon.
Large hailstorms, particularly in eastern Nebraska and southern Wisconsin, were key drivers of losses, Aon said in its latest catastrophe report.
Additional damage assessments are underway in Texas, where powerful hail events struck Williamson County during outbreaks from April 17–20 and April 21–23.
In Georgetown and Round Rock, Texas, local reports indicated that hundreds to potentially thousands of homes and vehicles sustained damage from exceptionally large hailstones. Images from the April 23 storm show properties with destroyed roofs and vehicles with heavy frame damage.
Eastern Nebraska was among the hardest-hit regions during the April 17–20 outbreak, where an EF3 tornado and widespread hail damaged roofing, siding, and windows, and broke or dented vehicle windshields.
Tornadoes and straight-line winds also caused destruction across northern Texas, Arkansas, Missouri, and Nebraska.
Property and casualty insurers have already faced significant storm-related losses in 2024. Allstate Corp. reported $1.04bn in pretax catastrophe losses in March alone, bringing total first-quarter losses to $2.2bn.
According to Allstate, four major wind and hail systems accounted for roughly 80% of those losses.
In late April 2025, a series of severe weather events impacted multiple U.S. states, resulting in significant property damage and substantial insured losses.
Nebraska and Iowa
Eastern Nebraska and western Iowa experienced a destructive tornado outbreak from April 25 to 28. An EF4 tornado near Elkhorn, Nebraska, leveled numerous homes and injured several individuals.
Another EF3 tornado struck an industrial building in Lincoln, Nebraska, injuring three people and derailing a freight train.
In Minden, Iowa, approximately 40 to 50 homes were destroyed, leading to one fatality and multiple injuries. The outbreak resulted in over 10,000 power outages in the Omaha area.
Texas and Oklahoma
Central and northern Texas, along with southern Oklahoma, faced severe storms characterized by large hail and multiple tornadoes. Hailstones up to 5.2 inches in diameter were reported near Guthrie, Texas. The Texas Panhandle experienced nearly a dozen tornadoes, with significant hail damage reported in Floyd County.
Midwest Region
Southern Minnesota, northern Iowa, and western Wisconsin were affected by severe thunderstorms, producing hail up to 2.8 inches in diameter and multiple tornadoes. A tornado near Fairmont, Minnesota, was confirmed, and additional tornado sightings were reported around Winnebago, Minnesota.
The late April severe weather events underscore the importance of preparedness and resilience in the face of increasingly frequent and intense storms.
