Aon reported that severe storms in both the United States and Europe in late May and early June 2025 caused insured losses totaling hundreds of millions of dollars across both regions.
In the U.S., storm systems from May 29–30 and June 1–4 caused widespread damage, particularly in the Dallas-Fort Worth Metroplex, which experienced significant wind and hail losses.
Flooding also affected the Wichita, Kansas area, with storm activity extending to the East Coast.
State Farm received nearly 5,500 claims in Texas, most filed between June 1 and June 4, according to spokesperson Michal Brower.
Additional claims included 280 in Illinois, 175 in Missouri, and 170 in Kansas. Aon also noted storm impacts in Iowa, Illinois, and Missouri, states already hit hard by prior convective storm activity in 2025.
Earlier, an EF3 tornado on May 22 traveled 22.8 miles through northern St. Louis and into Illinois, part of a broader outbreak that likely caused $4 bn to $7 bn in insured losses.

Additional storms after that outbreak caused billions more in damage, Aon stated.
At the beginning of June, straight-line winds and tornadoes in the Kansas City, Missouri area downed power lines, toppled trees, and damaged vehicles on two interstates.
In Europe, storms from May 31 to June 4 brought large hail, strong winds, and localized heavy rainfall across Western and Central Europe.
Early damage was concentrated in Western Europe, later shifting eastward. Hailstones over 2 inches in diameter were reported in the Netherlands, Germany, Poland, Slovenia, and Hungary. In France’s Puy-de-Dôme region, hailstones reached 3.9 inches.
