Evidence / storm surfaces
How Flat Rock 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 Sep 22, 2026 — this storm produced no NEXRAD point detections over Flat Rock, so there is one map to show, not two.
The storm in context
Where Sep 22, 2026 sits in Flat Rock's hail record.
This was Flat Rock's 7th recorded hail day, arriving 33 days after the Aug 20, 2026 storm. By severity it ranks 4th of the 7 storms we have logged here. Radar put the day's largest stone over Flat Rock at 0.75" — radar-estimated size aloft.
The Sep 22, 2026 convective day was bigger than Flat Rock: the same system put hail over 97 other tracked cities, 37 of them in Alabama. Nearest: Ider (9 miles southeast, up to 0.5"); Scottsboro (23 miles west, up to 0.5"); Sewanee (24 miles northwest, up to 0.5").

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 Flat Rock 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.
Near the severe threshold
What 0.75" hail means for Flat Rock roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$2.5M
Potential roof exposure — 207 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 207 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
September 2028
Claims from this storm can typically be filed until around September 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 $43 on top of the $150 plan.
