A series of severe storms that swept across the central and eastern United States in the final week of April is expected to result in insured losses amounting to hundreds of millions of dollars, according to a new report from Aon.
The firm also reported that Canadian insurers experienced damage on April 29 when high winds caused structural impacts, including fallen trees, roof damage, and wall collapses.
In its latest catastrophe report, Aon identified Texas, Oklahoma, and southern Missouri as some of the most affected areas. Hail measuring 5.2 inches was recorded in Texas. Additional damage was reported across Ohio and Pennsylvania because of a long-lived line of thunderstorms.
According to the National Weather Service in Lubbock, Texas, storms that occurred between April 24 and 26 involved rotating systems that produced hail and rain, at times obscuring the presence of tornadoes and reducing warning visibility.
The late April events follow other recent convective weather that also produced expected insured losses in the hundreds of millions, Aon noted. The firm added that further flooding persisted in areas of the southern United States, including Oklahoma and Louisiana.
On April 29 alone, the federal Storm Prediction Center logged 781 combined reports of tornadoes, hail, and wind from New Mexico to New York. Multiple other reports were filed during the broader April 27–29 outbreak, spanning much of the central and eastern US.
Aon recently noted that global insured catastrophe losses for the first quarter of 2025 are projected to reach or exceed US$53 billion. Of that total, US$37.5 billion – or 71% – is attributed to January wildfires in the Los Angeles area.
The Palisades and Eaton Fires destroyed over 18,000 structures. These events resulted in insured losses estimated at US$37.5 billion, contributing to a total of US$56 billion in insured catastrophe losses for the first quarter of 2025, marking it as the costliest first quarter since 2011
The remaining losses were largely connected to severe convective storms in the US during February and March, as well as earthquakes in Myanmar and China.
From March 13 to 16, a series of severe convective storms, including tornadoes and hail, impacted parts of the US. Preliminary assessments estimate insured losses between US$1 billion and US$3 billion, making it the first billion-dollar severe convective storm event of the year.
