Evidence / storm surfaces
How Tampa 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.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
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.
The storm in context
Where Sep 11, 2026 sits in Tampa's hail record.
This was Tampa's 9th recorded hail day, arriving 13 days after the Aug 29, 2026 storm. By severity it ranks 8th of the 10 storms we have logged here. Radar put the day's largest stone over Tampa at 0.5" — radar-estimated size aloft.
The Sep 11, 2026 convective day was bigger than Tampa: the same system put hail over 322 other tracked cities, 7 of them in Florida. Nearest: Thonotosassa (20 miles east, up to 0.5"); Webster (41 miles northeast, up to 0.5"); Fort Myers (106 miles southeast, 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.
The National Weather Service logged no spotter reports for this storm over Tampa. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Below the severe threshold
What 0.5" hail means for Tampa 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
$40M
Potential roof exposure — 3,339 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 17 jobs
- Illustrative work
- ~$255K
Close just 0.5% of the 3,339 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 $701 on top of the $150 plan.
