Evidence / storm surfaces
How San Manuel 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 Jul 13, 2026 — this storm produced no NEXRAD point detections over San Manuel, so there is one map to show, not two.
The storm in context
Where Jul 13, 2026 sits in San Manuel's hail record.
This was San Manuel's 2nd recorded hail day, arriving 2 days after the Jul 11, 2026 storm. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over San Manuel at 0.5" — radar-estimated size aloft.
The Jul 13, 2026 convective day was bigger than San Manuel: the same system put hail over 92 other tracked cities, 9 of them in Arizona. Nearest: Mammoth (9 miles northwest, up to 0.5"); Kearny (30 miles northwest, up to 0.75"); Florence (53 miles northwest, up to 1.25").
These maps are stills. In the app this date is one of 4 San Manuel 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 San Manuel. 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 San Manuel 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.
