Evidence / storm surfaces
How Altamont 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 Jun 11, 2026 — this storm produced no NEXRAD point detections over Altamont, so there is one map to show, not two.
The storm in context
Where Jun 11, 2026 sits in Altamont's hail record.
This was Altamont's 4th recorded hail day, arriving 46 days after the Apr 26, 2026 storm. By severity it ranks 4th of the 6 storms we have logged here. Radar put the day's largest stone over Altamont at 1.5" — radar-estimated size aloft.
The Jun 11, 2026 convective day was bigger than Altamont: the same system put hail over 648 other tracked cities, 12 of them in Kansas. Nearest: Edna (7 miles south, up to 2"); Mound Valley (9 miles northwest, up to 1.5"); Oswego (13 miles northeast, up to 2.25").
These maps are stills. In the app this date is one of 6 Altamont 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.
Hail reports
1 reportHigh damage potential
What 1.5" hail means for Altamont 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
$16M
Potential roof exposure — 1,295 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 6 jobs
- Illustrative work
- ~$90K
Close just 0.5% of the 1,295 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
June 2028
Claims from this storm can typically be filed until around June 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 $272 on top of the $150 plan.
