NEXRAD logged 9 hail signatures up to 2.5"; the estimated-size surface reached 1.25" aloft. At 2.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.

Evidence / storm surfaces
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.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
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.
The storm in context
This was Mobile's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd of the 16 storms we have logged here. Radar put the day's largest stone over Mobile at 2.5" — the largest NEXRAD radar signature.
The May 7, 2026 convective day was bigger than Mobile: the same system put hail over 48 other tracked cities, 10 of them in Alabama. Nearest: Lucedale (19 miles west, up to 1"); Vancleave (24 miles west, up to 1"); Fairhope (28 miles southeast, up to 3").
These maps are stills. In the app this date is one of 16 Mobile 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
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.
“NWS storm survey confirms a low-end EF1 tornado with maximum winds of 88 mph occurred northeast of Grand Bay... moving southeast toward i-10 before quickly dissipating. (MOB)”
— NOAA / SPC storm report
“Corrects previous tornado report from 3 SE Dees. Preliminary ground survey confirms low end EF1 damage northeast of Grand Bay... Alabama. Maximum intensity of 88 mph wa (MOB)”
— NOAA / SPC storm report
Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Dees — beyond Mobile itself.
Severe hail signal
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
Potential roof exposure
$41M
Potential roof exposure — 3,439 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 3,439 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 $722 on top of the $150 plan.
