Evidence / storm surfaces
How La Crescent saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Aug 18, 2026 — this storm produced no NEXRAD point detections over La Crescent, so there is one map to show, not two.
The storm in context
Where Aug 18, 2026 sits in La Crescent's hail record.
This was La Crescent's 8th recorded hail day, arriving 32 days after the Jul 17, 2026 storm. By severity it ranks 1st of the 9 storms we have logged here. Radar put the day's largest stone over La Crescent at 1.25" — radar-estimated size aloft.
The Aug 18, 2026 convective day was bigger than La Crescent: the same system put hail over 309 other tracked cities, 19 of them in Minnesota. Nearest: Onalaska (10 miles east, up to 1"); Winona (10 miles northwest, up to 1.25"); Houston (10 miles west, up to 0.5").
These maps are stills. In the app this date is one of 9 La Crescent 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 La Crescent 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.
Damage-capable hail signal
What 1.25" hail means for La Crescent roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$11M
Potential roof exposure — 947 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 947 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
August 2028
Claims from this storm can typically be filed until around August 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 $199 on top of the $150 plan.
