Evidence / storm surfaces
How Saint Augustine saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Aug 18, 2026 — this storm produced no NEXRAD point detections over Saint Augustine, so there is one map to show, not two.
The storm in context
Where Aug 18, 2026 sits in Saint Augustine's hail record.
This was Saint Augustine's 15th recorded hail day, arriving 19 days after the Jul 30, 2026 storm. By severity it ranks 18th of the 20 storms we have logged here. Radar put the day's largest stone over Saint Augustine at 0.5" — radar-estimated size aloft.
The Aug 18, 2026 convective day was bigger than Saint Augustine: the same system put hail over 309 other tracked cities, 38 of them in Florida. Nearest: Pomona Park (27 miles southwest, up to 1"); Palatka (30 miles southwest, up to 1"); Hollister (30 miles southwest, up to 1").

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.
For this storm over Saint Augustine, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0.5" hail means for Saint Augustine 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.
