Increasing property insurance costs are a growing concern for millions of current or prospective homeowners. A buyer’s ability to pay for their mortgage, interest, taxes and general maintenance costs has traditionally dictated their ability to afford being a homeowner. To date, the cost of insurance, which is included in the monthly payments, has been manageable. But rate increases due to insured loss increases are changing the arithmetic.

The frequency and severity of natural disasters - combined with increased development and inflation - are driving forces behind the proposed rate increases that put pressure on homeowners’ monthly payments. While large, costly and devastating events like hurricanes and wildfires dominate headlines about rising property costs, a quieter yet significant peril continues to drive insured natural disaster losses across the U.S.

Severe convective storms (SCS), also known as severe thunderstorms, impact millions of homes across the U.S. every year. SCS loss includes damage to property from straight-line winds, hail, and tornadoes. One defining characteristic of SCS compared to hurricanes or earthquakes, is that they can occur frequently—sometimes daily—and their cumulative impact over the course of a year, with many smaller losses adding up, can make them a significant driver of loss. While the losses from a single day of SCS activity may not be material enough to warrant attention, the total cost of thousands or even millions of claims over time becomes substantial.

In the CoreLogic® 2025 Severe Convective Storm Risk Report, readers will gain a better understanding of:

• frequency and severity of SCS over the last year
• the magnitude and geographic extent of SCS risk in the U.S. this year
• how SCS activity and losses could change in the future.
