Evidence / storm surfaces
How Ajo 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 Aug 9, 2026 — this storm produced no NEXRAD point detections over Ajo, so there is one map to show, not two.
The storm in context
Where Aug 9, 2026 sits in Ajo's hail record.
This was Ajo's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Ajo at 1" — radar-estimated size aloft.
The Aug 9, 2026 convective day was bigger than Ajo: the same system put hail over 453 other tracked cities, 20 of them in Arizona. Nearest: Dateland (53 miles northwest, up to 1"); Maricopa (59 miles northeast, up to 0.5"); Arlington (69 miles north, up to 0.5").
These maps are stills. In the app this date is one of 1 Ajo storm date 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.
The National Weather Service logged no spotter reports for this storm over Ajo. 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.
Damage-capable hail signal
What 1" hail means for Ajo roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.
