The Weekly: The Rising Costs of Severe Convective Storms

Several drivers are contributing to the rise in expensive severe convective storms: 1) population growth in high-risk areas; 2) non-resilient physical assets; and 3) rising building premiums.

Late last night, severe thunderstorms rolled through much of the Midwest, dropping large hail and heavy rain across the region. Flooding is impacting parts of central Ohio this morning, and flood warnings are likely to persist through Friday evening.

This latest storm system follows what has already been a busy month for severe weather in the Midwest, drawing attention to the dynamics at play that make severe storms increasingly costly for communities nationwide.

Since 1980, roughly one in every two billion-dollar disasters in the U.S. has been a severe convective storm, defined as a storm producing high wind gusts exceeding 58 mph, a tornado, or hail. In 2025, 21 of the 23 billion-dollar disasters were severe convective storms, causing $51 billion in total U.S. damages. Globally, these disasters accounted for $61 billion of the $170 billion in total insured natural catastrophe losses, the third-highest severe convective storm total on record. 

Several drivers are contributing to the rise in expensive severe storms: 

Cost Driver #1: Population growth in areas prone to severe storms has increased asset exposure

Population growth has concentrated more people and assets in storm-prone corridors. Texas, one of the most hail-battered states in the country, grew 40% over the last two decades and continues to lead the nation in population growth. The South accounted for 87% of the U.S.’s total population growth in 2023 and added 1.2 million residents in 2025 alone. That influx has fueled new construction and development. A storm that once would have touched down in an empty field is now hitting a subdivision.

Cost Driver #2: The physical assets in harm's way are not designed to withstand high winds or hail

In 2022, State Farm reported that 80% of the company’s total claims paid for hail damage went to homeowners, and the overwhelming majority were for standard roofs that, in hail-prone areas, last half as long as roofs elsewhere (7-10 years vs. 20 years). Add to that aging windows, garage doors that aren’t wind-rated, unscreened HVAC units, and an expanding inventory of hail-vulnerable solar panels (on 7% of U.S. homes today, projected to double by 2030), and risk exposure grows.

Cost Driver #3: Building premiums to rebuild after severe storms are increasing

The cost to rebuild is also making storms more expensive. According to Swiss Re, building costs are rising faster than the overall rate of inflation, which leads to higher reconstruction costs and higher claims. Meanwhile, the average claim amount is increasing as the value of assets increases.

Where to Go From Here

No panacea can dramatically reduce the costs of severe storms. More people and assets in places that are likely to experience severe storms translates into higher costs. But there are steps that the private sector can take to fortify the assets across America’s heartland where such storms are most common. 

These opportunities to enhance resiliency and reduce costs, outlined in our Severe Storms Briefing Part II, include: 1) investing in more resilient roofing; 2) adopting more resilient construction practices; and 3) investing in new innovations and technologies.

Public Infrastructure

  • How Extreme Weather and Aging Infrastructure Led to Months of ‘Musty’ Water in One Ohio Village | Inside Climate News | A prolonged water crisis in Cadiz, Ohio, is illustrating how climate-driven weather shifts are complicating drinking water management for small communities. Many water utilities still rely on historical weather patterns to guide planning, even as climate change brings more volatile rainfall cycles that increase turbidity and strain outdated treatment plants.
  • Odds Rise That El Niño Will Soon Bring Weather Extremes | New York Times | NOAA now puts the odds of El Niño arriving by August at 80%, with a one-in-three chance it matches the severity of the 2023-24 event that drove record global temperatures. The timing is awkward: FEMA has shed thousands of workers, and an agency overhaul remains unresolved. A strong El Niño would test a disaster response apparatus that has been significantly hollowed out.

This piece argues that ESG and climate readiness are prerequisites for maintaining asset value, and suggests priority resilience measures across building engineering, supply chain control, and financing.

Private Investment

  • Why a Short, Sharp Climate Shock Affects Your Pension More Than a Slow, Looming Threat | The Conversation | Investors react faster to sudden climate events than to slow-moving risks like rising seas or prolonged drought, even when the long-term damage from the latter may be just as severe. Vivid, immediate risks capture attention in ways that gradual ones don't. For pension funds designed to manage risk over decades, that perceptual gap is a structural vulnerability.
