Evidence / storm surfaces
How San Diego saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Sep 5, 2026 — this storm produced no NEXRAD point detections over San Diego, so there is one map to show, not two.
The storm in context
Where Sep 5, 2026 sits in San Diego's hail record.
This was San Diego's 7th recorded hail day, arriving 2 days after the Sep 3, 2026 storm. By severity it ranks 7th of the 7 storms we have logged here. Radar put the day's largest stone over San Diego at 0.5" — radar-estimated size aloft.
The Sep 5, 2026 convective day was bigger than San Diego: the same system put hail over 514 other tracked cities, 3 of them in Texas. Nearest: San Ygnacio (51 miles southwest, up to 0.5"); Moscow (333 miles northeast, up to 0.5"); Converse (427 miles northeast, up to 0.5").
These maps are stills. In the app this date is one of 7 San Diego 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.
Nobody on the ground filed a report over San Diego 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.
Below the severe threshold
What 0.5" hail means for San Diego 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.
