Texas Billion-Dollar Weather Disasters: 45 Years of NOAA Data
NOAA's National Centers for Environmental Information have tracked 190 separate billion-dollar weather and climate disasters in Texas from 1980 through 2024, with combined costs in the $300-440 billion range -- and severe storm events (the category hail and wind damage falls under) are by far the most frequent type at 126 of those 190 events (66.3%), even though tropical cyclones caused a larger share of total dollar losses. The frequency of these events has also accelerated sharply: the 1980-2024 annual average is 4.2 billion-dollar disasters per year, but the most recent five years (2020-2024) averaged 13.6 per year.

What NOAA's Texas disaster data actually shows
This is NOAA's own confirmed-loss tracking, not a modeled estimate -- each event meets a specific billion-dollar damage threshold before being counted.
- Severe storm events (hail, wind, tornado activity) account for 126 of Texas's 190 billion-dollar disasters since 1980 -- 66.3% of all events -- with $50-100 billion in combined costs (22.6% of the state's total).
- Tropical cyclones caused far fewer events (16, or 8.4% of the total) but the largest share of total cost ($200-300 billion, 56.9% of the state's total) -- a small number of major hurricanes drive most of the dollar figure, while severe storms drive most of the event count.
- Drought (20 events), winter storms (11 events), flooding (9 events), wildfire (7 events), and a single freeze event round out the remaining categories.
- The clearest trend in the data is frequency, not just cost: the 45-year annual average of 4.2 billion-dollar disasters per year has more than tripled to 13.6 per year over 2020-2024.
- NOAA's cost figures are CPI-unadjusted totals as published in the tool's state-summary view, covering direct and indirect economic losses NOAA can verify -- not an insurance-claims figure specifically.
Why the severe-storm frequency trend matters for roofing
- Severe storm events being the single most frequent disaster category in Texas (not tropical cyclones) lines up with why hail and wind roof damage claims are a year-round concern across the state's hail corridor, not just a hurricane-season risk.
- A near-tripling in annual disaster frequency over the last five tracked years is consistent with what insurers and roofers in this market have been reporting anecdotally -- this NOAA data is the federal confirmation of that trend, not just a local impression.
- This statewide, multi-decade view is a deliberately different angle from the county-level hail-event-count and FEMA relative-risk-score guides already on this site -- this one tracks confirmed economic losses and event frequency over time, not local incident counts or a modeled risk rating.

Frequently Asked Questions
Does NOAA's billion-dollar disaster count include every hailstorm in Texas?
No. NOAA only counts an event once its confirmed damages reach the billion-dollar threshold, so this tracks major, high-cost events -- not every hailstorm that causes roof damage to individual homes, most of which fall well under that threshold.
Why do tropical cyclones cost more but happen less often than severe storms?
A single major hurricane can cause tens of billions of dollars in damage across a wide area in one event, while severe storm (hail/wind) events are more frequent but each one typically affects a smaller area and causes less total damage than a major hurricane.
Is the increase in disaster frequency specific to Texas or a national pattern?
NOAA's national data shows a similar acceleration across the U.S. as a whole, so Texas's trend is consistent with the national pattern rather than unique to the state -- though Texas is one of the states most frequently affected given its size and exposure to both severe storms and tropical cyclones.
