Evidence / storm surfaces
How Houston saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Sep 1, 2026 — this storm produced no NEXRAD point detections over Houston, so there is one map to show, not two.
The storm in context
Where Sep 1, 2026 sits in Houston's hail record.
This was Houston's 9th recorded hail day, arriving 14 days after the Aug 18, 2026 storm. By severity it ranks 1st of the 9 storms we have logged here. Radar put the day's largest stone over Houston at 1.5" — radar-estimated size aloft.
The Sep 1, 2026 convective day was bigger than Houston: the same system put hail over 362 other tracked cities, 56 of them in Minnesota. Nearest: Winona (7 miles north, up to 1.5"); La Crescent (10 miles east, up to 1.25"); Lewiston (10 miles west, up to 1").
These maps are stills. In the app this date is one of 9 Houston storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.
Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
No ground reports were filed with the National Weather Service for this storm over Houston. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
High damage potential
What 1.5" hail means for Houston roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$7.7M
Potential roof exposure — 643 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 3 jobs
- Illustrative work
- ~$45K
Close just 0.5% of the 643 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
September 2028
Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $135 on top of the $150 plan.
