Evidence / storm surfaces
How Tonto Basin 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 29, 2026 — this storm produced no NEXRAD point detections over Tonto Basin, so there is one map to show, not two.
The storm in context
Where Sep 29, 2026 sits in Tonto Basin's hail record.
This was Tonto Basin's 3rd recorded hail day, arriving 78 days after the Jul 13, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Tonto Basin at 0.5" — radar-estimated size aloft.
The Sep 29, 2026 convective day was bigger than Tonto Basin: the same system put hail over 22 other tracked cities, 5 of them in Arizona. Nearest: Fort Mcdowell (23 miles southwest, up to 0.5"); Payson (28 miles north, up to 0.5"); Willcox (140 miles southeast, up to 0.5").
These maps are stills. In the app this date is one of 3 Tonto Basin 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 Tonto Basin. 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 Tonto Basin 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.
