Evidence / storm surfaces
How Jacksonville saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Sep 12, 2026 — this storm produced no NEXRAD point detections over Jacksonville, so there is one map to show, not two.
The storm in context
Where Sep 12, 2026 sits in Jacksonville's hail record.
This was Jacksonville's 28th recorded hail day, arriving 1 day after the Sep 11, 2026 storm. By severity it ranks 19th of the 28 storms we have logged here. Radar put the day's largest stone over Jacksonville at 0.5" — radar-estimated size aloft.
The Sep 12, 2026 convective day was bigger than Jacksonville: the same system put hail over 354 other tracked cities, 5 of them in Florida. Nearest: Patterson (88 miles north, up to 0.5"); Blackshear (90 miles northwest, up to 0.5"); Tavares (97 miles south, up to 0.75").
These maps are stills. In the app this date is one of 28 Jacksonville 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.
No ground reports were filed with the National Weather Service for this storm over Jacksonville. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Below the severe threshold
What 0.5" hail means for Jacksonville roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$26M
Potential roof exposure — 2,183 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 11 jobs
- Illustrative work
- ~$165K
Close just 0.5% of the 2,183 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 $458 on top of the $150 plan.
