Texas: A Microcosm
of U.S. Climate Perils

Devastating flooding in central Texas over the July 4, 2025, weekend highlighted several aspects of the state’s risk profile that also are relevant to the rest of the country, according to the latest Triple-I Issues Brief. One is the rising incidence of severe inland flooding related to tropical storms.

Tropical Storm Barry made landfall in Mexico on June 29 and weakened quickly, but its remnant moisture drifted northward into Texas, according to Dr. Phil Klotzbach, a research scientist in the Department of Atmospheric Science at Colorado State University and a Triple-I non-resident scholar.

“A slow-moving low-pressure area developed and helped bring up the moisture-rich air rom Barry and concentrated it over the Hill Country of central Texas,” Klotzbach said. “The soil was also extremely hard from prior drought conditions, which exacerbated the flash flooding that occurred.”

Such flooding far from landfall has become more frequent and severe in recent years.  In Texas – as in much of the United States, particularly far from the coasts – few homeowners have flood insurance. Many believe flood damage is covered by their homeowners’ or renters’ insurance. Others believe the coverage is not worth buying if their mortgage lender doesn’t require it.  In Kerr County, where much of the July 4 flooding took place, flood insurance take-up rates through the National Flood Insurance Program (NFIP) were 2.5 percent.

Convective storms, fires, and freezes

But tropical storms aren’t always the impetus for flooding. In July 2023, a series of intense thunderstorms resulted in heavy rainfall, deadly flash floods, and severe river flooding in eastern Kentucky and central Appalachia. The conditions that lead to such severe convective storms also are prevalent in Texas.

Severe convective storms are a growing source of losses for property/casualty insurers. According to Gallagher Re, severe convective storm events in 2023 and 2024 “have cost global insurers a remarkable US$143 billion, of which US$120 billion occurred in the U.S. alone.”

Given its aridity and winds, it should be no surprise that Texas is highly subject to wildfire – but the state also has been increasingly prone to severe winter storms and debilitating freezes. On Valentine’s Day 2021, snow fell across most of Texas, accumulating as temperatures stayed below freezing and precipitation continued through the night. A catastrophic failure of the state’s independent electric grid exacerbated these conditions as snow and ice shut down roads and many homes suffered pipe bursts and multiple days without power.

Texas’s 2021 experience illustrates how grid instability can act as a “risk multiplier” for natural disasters. The entire U.S. electric power grid is increasingly vulnerable as the infrastructure ages and proliferating AI data centers increase demand.  

Need for data and collaboration

The severe damage and loss of life from the July 4 flooding have naturally raised the question of whether the Trump Administration’s reductions in National Weather Service  staffing contributed to the high human cost of this event. While it is hard to say with certainty, these cuts have affected how NWS works – for example, in its use of weather balloons to monitor weather. As early as April, staffing data gathered by NWS indicated that field offices were “critically understaffed”.

In June, panelists at Triple-I’s Joint Industry Forum expressed concern about the impact of the federal cuts on weather monitoring and modeling, as well as programs to help communities adequately prepare for and recover from disasters. Triple-I has published extensively on the need for insurers to shift from exclusively focusing on repairing and replacing property to predicting events and preventing damage.

Collective action at all levels – individual, commercial, and government – is needed to mitigate risks, build resilience, and reduce fraud and legal system abuse. Triple-I and its members are committed to fostering such action and regularly provide data and analysis to inform the necessary conversations.

Insurance Affordability, Availability Demand Collaboration, Innovation

By Lewis Nibbelin, Contributing Writer, Triple-I

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

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.
