Evidence / storm surfaces
How Ona 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 10, 2026 — this storm produced no NEXRAD point detections over Ona, so there is one map to show, not two.
The storm in context
Where Sep 10, 2026 sits in Ona's hail record.
This was Ona's 11th recorded hail day, arriving 46 days after the Jul 26, 2026 storm. By severity it ranks 8th of the 11 storms we have logged here. Radar put the day's largest stone over Ona at 0.5" — radar-estimated size aloft.
The Sep 10, 2026 convective day was bigger than Ona: the same system put hail over 94 other tracked cities, 23 of them in Florida. Nearest: Zolfo Springs (18 miles east, up to 0.5"); Sebring (31 miles east, up to 0.75"); Fort Meade (33 miles northeast, up to 0.75").

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 Ona. 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 Ona 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
$12K
Potential roof exposure — 1 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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.
