In a year marked by severe convective storm-induced damage across the United States, timely and accurate data is more essential than ever to understand, predict, and prevent these evolving weather perils. Though federal cuts to weather monitoring and modeling have raised concerns about the industry’s capacity for risk mitigation, a new research center backed by insurers and the U.S. National Science Foundation (NSF) aims to help bridge the gap.

Directed by Dr. Victor Gensini, a professor at Northern Illinois University and a Triple-I non-resident scholar, the Center for Interdisciplinary Research on Convective Storms (CIRCS) will leverage the expertise of nearly two dozen scientists to develop research focused on advancing resilience against severe convective storms, which range from thunderstorms with lightning to tornadoes, straight-line winds, and hail.

Northern Illinois University and the University of Wisconsin-Madison launched CIRCS with $1.5 million in funding from NSF, as part of a joint initiative with the National Oceanic and Atmospheric Administration (NOAA) to create an Industry-University Cooperative Research Center (IUCRC) that can support the insurance sector.

Beyond funds under the IUCRC model, CIRCS also receives “funding for research, students, and lab equipment” from private industry members, most of whom are “insurance and reinsurance companies interested in research on convective storms,” said Gensini, who teaches in NIU’s Department of Earth, Atmosphere, and Environment. He added that CIRCS includes actuarial scientists within its panel of experts to “approach this specific peril from multiple directions.”

Rising in both frequency and severity, convective storms accounted for $42 billion in global insured losses during the first half of 2024 alone, driven by 12 U.S. storms with $1 billion or more in losses each, according to a Swiss Re report. Large U.S. thunderstorms contributed to the second-costliest half-year ever for global insured losses in 2025, triggering a surge in flash flooding that highlights the growing flood protection gap in inland areas.

Paradigm-setting research

In addition to the center’s launch, Gensini recently celebrated a major data haul gathered during the largest hail study ever conducted, known as ICECHIP – short for In-situ Collaborative Experiment for Collection of Hail in the Plains. Funded with an $11 million grant from NSF, the field study sent Gensini and more than 100 other scientists and students across the Great Plains to chase and analyze hailstorms, which facilitate as much as 80 percent of severe convective storm claims in any one year.

Collecting more than 10,000 stones for study, the researchers hope to reduce hail risk through improved forecasting, enabling residents to better protect themselves and their belongings before a hailstorm hits. As the first field campaign dedicated to studying hail since the 1970s, ICECHIP’s participants expect their data to inform research analysis for years to come, NIU reported.

“We recovered tennis-ball-sized hail or greater in about half of our instrument deployments,” Gensini said. “You hope and dream for these kinds of observations in order to push forward hail science.”

By partnering academia with industry and government agencies, CIRCS and ICECHIP showcase the kinds of collaborative, data-driven solutions needed to address climate risks in ways that respect the unique needs of all affected groups, fostering risk management strategies that can build resilience at a community level.

Storm-Resistant Roof Efforts Gain Ground

Severe convective storms cost insurers an estimated $46 billion in the first three quarters of 2025, Gallagher Re has reported, marking the third straight year of U.S. claims from these events through September exceeding $40 billion. Total losses from these storms – which include tornadoes, hail, straight-line winds, and drenching thunderstorms – reflect growing impacts from inland flooding and, in particular, the vulnerability of roofs to damage from these storms.

Approximately 70 to 90 percent of total insured residential catastrophic losses arise from roof-related damage, according to Insurance Institute for Business & Home Safety (IBHS) estimates. Though poorly maintained roofs contribute to this finding, outdated building codes exacerbate the risk, leading insurance industry leaders to advocate for widespread adoption of FORTIFIED roof standards.

Developed by IBHS, FORTIFIED standards can reduce severe weather damage in new or retrofitted homes through construction methods like sealing roof decks and anchoring roofs to wall framing using stronger nails. While such standards remain voluntary, Louisiana has modelled the proactive approach needed to facilitate adoption with the recent expansion of its Louisiana Fortify Homes Program, which began offering homeowners thousand-dollar grants to retrofit their houses along these guidelines in 2023, incentivizing roughly 40 percent of the now 10,000 FORTIFIED roofs in the state.

“FORTIFIED roofs are the long-term solution for affordable insurance in South Louisiana,” said state insurance commissioner Tim Temple, noting that his office aims to implement bigger and more standardized insurance discounts for FORTIFIED homeowners to reinforce the state’s already improved insurance rates.

An emerging trend

Though Louisiana became the “fastest-growing state” to adopt FORTIFIED standards, Alabama pioneered incentivizing them through its own Strengthen Alabama Homes program, financed by the insurance industry with more than $86 million in grants since 2016. Designed to enhance community resiliency while also lowering insurance rates, completed retrofits qualify residents for premium discounts ranging from 25 to 55 percent.

A May 2025 study from the Alabama Department of Insurance, in collaboration with the University of Alabama Center for Insurance Information and Research, showcases the program’s success, highlighting that FORTIFIED homes suffered less property damage and fewer insurance claims than homes built using other construction methods when Hurricane Sally made landfall in the state.

“The Center’s Hurricane Sally report doesn’t just quantify the effectiveness of the FORTIFIED program, it clearly demonstrates that homes can be built to survive storms, making them eminently more insurable,” said IBHS CEO Roy Wright. “This report should be a clarion call to communities across the country, urging them to implement Alabama’s multipronged approach to promoting disaster mitigation.”

Insurers answered the call in Oklahoma, North Carolina, and South Carolina, all of which boast similar programs backed by the insurance sector and accompanying premium reductions. Mississippi nearly joined their ranks before state funding for the grant program was suspended earlier this year, though insurance discounts remain available. States such as Florida, Georgia, and Minnesota also offer comprehensive insurance discounts for FORTIFIED properties, with the latter poised to fully replicate a grant program in response to mounting hailstorms.

Addressing cost concerns

While 75 percent of homeowners express willingness to invest in weather-resistant features, only 18 percent have reinforced or replaced their roofs with those materials, a recent Nationwide survey reveals. Grants help lower the cost of entry to FORTIFIED roofs for many homeowners, but it is worth noting the relative affordability of such upgrades, which can cost as little as $500 for a 2,000 sq. ft. home.

Describing the benefits of FORTIFIED standards as “measurable and increasingly essential,” Nationwide Property & Casualty president and COO Mark Berven emphasized the crucial role insurance agents play in raising consumer awareness of these risk reductions and their broad accessibility.

“Our industry needs to remind homeowners they have control in the face of severe weather events,” Berven wrote. “By investing in resilience, they can take an active role in protecting their homes, their valuables and their memories – giving them the peace of mind they’re looking for.”

Resilience Investment Payoffs Outpace Future Costs More Than 30 Times

Every dollar invested in disaster resilience today can save communities up to $33 in avoided economic costs, according to new research from the U.S. Chamber of Commerce, Allstate, and the U.S. Chamber of Commerce Foundation.

Building on their 2024 finding that such investments save $13 in benefits, the report detailed the burgeoning toll of increasingly frequent and severe natural catastrophes across the United States, underscoring a need for stronger collective action to mitigate climate risk.

Invest Now, Save Later

After experiencing the fifth consecutive year of 18 or more billion-dollar disasters in 2024, the United States further drove the second costliest half-year ever for global insured losses from natural catastrophes in 2025 with January’s devastating wildfires in Southern California. Though reflecting a troubling “new normal,” the report demonstrates how resilience funding can help stabilize local economies and protect lives and jobs, regardless of the scale or type of disaster.

Modeling scenarios for five disaster types – hurricanes, tornadoes, wildfires, droughts, and floods – the study revealed that high resilience investments may cut GDP losses by billions, with reduced funding leading to significantly higher long-term costs across all scenarios.

For hurricane-prone areas, which can grapple with lasting disruptions to housing, education, and other basic infrastructure, the study noted that higher investment could prevent the loss of $13.2 billion and more than 70,000 jobs.

Emphasizing the “smart, cost-saving” efficacy of disaster mitigation, the report concluded that “preparedness is not just a safety measure – it’s a local economic development strategy.”

“Preparedness is as much about plans as it is people,” added Rich Loconte, senior vice president and deputy general counsel for government and industry relations at Allstate. “It’s supporting a local nonprofit to retain its employees and keeps its doors open after a disaster, working with civic leaders to develop recovery plans that minimize rebuilding costs, and educating community members on proactive investments that help better weather storms.”

Risk Reduction in Practice

Beyond identifying the broad impact of disaster preparedness, the report also provides actionable insights for local leaders who aim to boost community resilience but are unsure where or how to start. Recommendations for disaster preparation include:

  • Risk-Informed Design: Adopt and enforce hazard-resistant building codes, such as those that meet the Insurance Institute for Business & Home Safety’s FORTIFIED standards. Update zoning and land use planning according to the latest risk data.
  • Data-Based Decisions: Improve access to risk data to inform, track, and assess the success of disaster mitigation efforts.
  • Dedicated Resilience Funding:Create a local fund for disaster mitigation to ensure consistent investment and expedite post-disaster recovery.
  • Public Engagement: Launch risk awareness campaigns to facilitate individual and organized participation in preparedness and raise insurance take-up rates.
  • Stakeholder Partnerships: Coordinate cross-sector and multi-jurisdictional resilience strategies to maximize benefits.

A survey released in tandem with the report shows that most resilience stakeholders – encompassing emergency managers, community planners, government officials, and other risk experts –  believe public-private collaboration needs improvement, with more than half of respondents highlighting insufficient resource allocation and unclear decision-making processes as leading causes for poor coordination.

While most indicated state and local governments must play a major role in disaster preparedness, response, and recovery, 58 percent of respondents additionally underscored the federal government as crucial at every phase, particularly for financial assistance. As numerous community resilience projects hang in limbo following the Trump Administration’s cancellation of $882 million in federal grants, it is imperative for all beneficiaries of disaster resilience to help develop sensible solutions for predicting and preventing losses.

“As the cost and economic toll of disasters continue to increase, leaders at all levels of government should know that investments in infrastructure resilience will go a long way in protecting and preparing local communities,” said Marty Durbin, senior vice president of policy at the U.S. Chamber of Commerce. “Resilience investments reduce costs and speed up recovery. The faster a community bounces back, the faster jobs and economic growth return.”

Some Weather Service Jobs Being Restored;
BRIC Still Being Litigated

Leave a comment

Amid a summer full of deadly fires and storm-related flooding, the Trump Administration appears to be rolling back some of the spending cuts imposed upon the National Weather Service (NWS) by the Department of Government Efficiency (DOGE).

The National Oceanic and Atmospheric Administration (NOAA) – of which NWS is a part – announced at an internal all-hands meeting earlier this month that they will hire 450 meteorologists, hydrologists, and radar technicians. CNN reported the announcement, citing an unnamed NOAA official. In jointly timed press releases, Congressmen Mike Flood and Eric Sorensen (D-Ill.) and Mike Flood (R-Neb.) acknowledged the planned hirings.

While the decision is welcome news, both congressmen continued to urge their colleagues to pass their bipartisan Weather Workforce Improvement Act to ensure these positions will remain permanent and not be subject to any future reductions. 

“For months, Congressman Flood and I have been fighting to get NOAA and NWS employees the support they need in the face of cuts to staff and funding,” Sorenson said. “Hundreds of unfilled positions have caused NWS offices across the country to cancel weather balloon launches, forgo overnight staffing, and force remaining meteorologists to overwork themselves.”

“For decades the National Weather Service has helped keep our communities safe with accurate and timely forecasts,” said Flood, adding that the NOAA announcement “sends a message that they’re focused on strengthening the NWS for years to come.”  

NOAA and FEMA cuts raised fears

It’s not just the NOAA and NWS cuts that have raised concerns. On April 4, 2025, the Federal Emergency Management Agency (FEMA) announced that it would be ending its Building Resilient Infrastructure and Communities (BRIC) program and cancel all BRIC applications from fiscal years 2020-2023. Congress established BRIC through the Disaster Recovery Reform Act of 2018 to ensure a stable funding source to support mitigation projects annually. The program has allocated more than $5 billion for investment in mitigation projects to alleviate human suffering and avoid economic losses from floods, wildfires, and other disasters.

At the time, Chad Berginnis, executive director of the Association of State Floodplain Managers (ASFPM), called the decision to terminate BRIC “beyond reckless.”

 “Although ASFPM has had some qualms about how FEMA’s BRIC program was implemented, it was still a cornerstone of our nation’s hazard mitigation strategy, and the agency has worked to make improvements each year,” Berginnis said. “Eliminating it entirely — mid-award cycle, no less — defies common sense.”

Resilience investment is key to long-term insurance availability and affordability.  Average insured catastrophe losses have been on the rise for decades, reflecting a combination of climate-related factors and demographic trends as more people have moved into harm’s way.

Efforts have been made to save BRIC, and a U.S. District Judge in Boston recently granted a preliminary injunction sought by 20 Democrat-led states while their lawsuit over the funding moves ahead. Judge Richard G. Stearns ruled the Trump Administration cannot reallocate $4 billion meant to help communities protect against natural disasters.

In his ruling, Stearns said he was not convinced Congress had given FEMA any discretion to redirect the funds. The states had also shown that the “balance of hardship and public interest” was in their favor.

“There is an inherent public interest in ensuring that the government follows the law, and the potential hardship accruing to the States from the funds being repurposed is great,” Stearns wrote. “The BRIC program is designed to protect against natural disasters and save lives.”

Insurance Affordability, Availability Demand Collaboration, Innovation

Insurance industry executives and thought leaders gathered yesterday for Triple-I’s Joint Industry Forum (JIF) in Chicago to discuss the trends, economics, geopolitics, and policy influencing the market today, as well as ways to navigate these complexities while focusing on making their products affordable and available for consumers.

Triple-I CEO Sean Kevelighan in his opening remarks, noted that effective risk management depends on collaboration across stakeholder groups, as interconnected perils “present a community problem, not just an industry problem.”

JIF keynote speaker Louisiana Insurance Commissioner Tim Temple said facilitating community resilience planning is a top priority for the National Association of Insurance Commissioners (NAIC). The NAIC’s 2025 initiative  – “Securing Tomorrow: Advancing State-Based Regulation” – aims to improve disaster mitigation and recovery by consolidating “the collective expertise of experienced state regulators from across the country, who can share real-time insights and proven strategies,” Temple said.

Among the initiative’s goals is aggregating more data from insurers to better understand challenges to affordability and availability on state levels, which the NAIC can then translate into actionable policy proposals. Such data calls, Temple said, help regulators, legislators, and policyholders focus on improving the cost drivers of insurance rates.

Louisiana has consistently been among the least affordable states for homeowners and auto insurance, according to the Insurance Research Council (IRC), in part because of its reputation for being plaintiff-friendly in civil litigation. Significant tort legislation has been approved in the state, but resistance to reform remains a challenge.

Getting to the roots of high premiums

 After a recent data call in his home state, Temple told the JIF audience, “For the first time in Louisiana, we’re not talking about only premiums. We’re talking about why premiums are where they are.”

A critical lack of transparency surrounding cost drivers persists, however. Temple criticized the National Flood Insurance Program’s Risk Rating 2.0 reforms for not publicly disclosing more information “for individuals and communities to identify and address factors driving up their premiums,” such as “whether increased rates take into account levee systems, pump stations, and other things designed to help mitigate against floods.”

Conversely, government programs like Strengthen Alabama Homes – and the numerous programs it inspired, including in Louisiana – have demonstrated success in communicating the benefits of resilience investments for consumers and policymakers.

“We’re seeing major positive results after just a few short years,” Temple said, noting that, since early 2024, over 5,000 homeowners not chosen for Louisiana’s grant program still decided to invest in the same hazard mitigation, as they may still qualify for the corresponding state-mandated insurance discounts.

“As natural disasters become more frequent and severe, state regulators will continue to drive forward common-sense policies that protect consumers and ensure that insurance remains available and reliable for at-risk communities,” Temple concluded. Developing the database required for such policies is a necessary first step.

2025 Tornadoes Highlight Convective Storm Losses

Leave a comment

Tornado activity in 2025 has surged, with more than 1,000 reported tornadoes as of May 28 and outbreaks spreading across nearly every state east of the Rockies this season, according to according to the NOAA Storm Prediction Center.

Researchers have highlighted a shift in both the timing and geography of tornadoes, raising new safety concerns for communities outside the traditional Tornado Alley states.  The widening prevalence of tornado activity has some experts suggesting that the name “Tornado Alley” be retired.

The 1,010 tornadoes reported is almost 40 percent higher than the 15-year average of 727 tornadoes for the same period. Mississippi leads with 97 tornado reports, followed by Illinois (93), Missouri (89), and Texas (87), according to AccuWeather.

Severe convective storms – which include tornadoes – are among the most common, most damaging natural catastrophes in the United States. The result of warm, moist air rising from the earth, they manifest in various ways, depending on atmospheric conditions – from drenching thunderstorms with lightning, to tornadoes, hail, or destructive straight-line winds.

In 2024, according to Gallagher Re, the economic cost solely from weather and climate events was approximately $402 billion ($151 billion insured).  At least 41 percent of insured losses ($64 billion) resulted from severe convective storms.

So far this year, Gallagher said, the United States has recorded at least eight separate billion-dollar insured loss events from SCS activity so far in 2025. This compares to 13 such events by the end of May in 2024, 11 in 2023, six in both 2022 and 2021, and 12 in 2020.

 In addition to tornadoes, Gallagher said, large hail – measuring two inches or more in diameter – was a major factor in driving losses.
