Evidence / storm surfaces
How Iraan saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for May 21, 2026 — this storm produced no NEXRAD point detections over Iraan, so there is one map to show, not two.
The storm in context
Where May 21, 2026 sits in Iraan's hail record.
This was Iraan's 3rd recorded hail day, arriving 2 days after the May 19, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Iraan at 1.5" — radar-estimated size aloft.
The May 21, 2026 convective day was bigger than Iraan: the same system put hail over 120 other tracked cities, 33 of them in Texas. Nearest: Ozona (52 miles south, up to 1.5"); Sanderson (58 miles southwest, up to 1"); Sonora (89 miles east, up to 1.25").
These maps are stills. In the app this date is one of 4 Iraan 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.
Nobody on the ground filed a report over Iraan for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
High damage potential
What 1.5" hail means for Iraan 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
$12M
Potential roof exposure — 999 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 5 jobs
- Illustrative work
- ~$75K
Close just 0.5% of the 999 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
May 2028
Claims from this storm can typically be filed until around May 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 $210 on top of the $150 plan.
