Hail in Lavina · Jul 16, 2026
The estimated-size surface reached 2" aloft; NEXRAD logged no point detections over Lavina that day. At 2" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Lavina 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.
Estimated size field 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 Jul 16, 2026 — this storm produced no NEXRAD point detections over Lavina, so there is one map to show, not two.
The storm in context
Where Jul 16, 2026 sits in Lavina's hail record.
This was Lavina's 3rd recorded hail day, arriving 2 days after the Jul 14, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Lavina at 2" — radar-estimated size aloft.
The Jul 16, 2026 convective day was bigger than Lavina: the same system put hail over 206 other tracked cities, 40 of them in Montana. Nearest: Broadview (19 miles southeast, up to 0.5"); Roundup (23 miles east, up to 1.5"); Acton (25 miles south, up to 0.5").
These maps are stills. In the app this date is one of 3 Lavina 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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked southeast at roughly 20 mph, based on the timing of ground reports.
Hail was reported over 47 minutes, from to .
Severe hail signal
What 2" hail means for Lavina roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$4.9M
Potential roof exposure — 405 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 405 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
July 2028
Claims from this storm can typically be filed until around July 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 $85 on top of the $150 plan.
