Evidence / storm surfaces
How Mountain Center 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 Sep 24, 2026 — this storm produced no NEXRAD point detections over Mountain Center, so there is one map to show, not two.
The storm in context
Where Sep 24, 2026 sits in Mountain Center's hail record.
This was Mountain Center's 2nd recorded hail day, arriving 45 days after the Aug 10, 2026 storm. By severity it ranks 2nd of the 2 storms we have logged here. Radar put the day's largest stone over Mountain Center at 0.75" — radar-estimated size aloft.
The Sep 24, 2026 convective day was bigger than Mountain Center: the same system put hail over 23 other tracked cities, 3 of them in California. Nearest: Anza (6 miles west, up to 0.5"); Joshua Tree (39 miles northeast, up to 0.5"); Twentynine Palms (49 miles northeast, up to 0.5").

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 Mountain Center. 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.
Near the severe threshold
What 0.75" hail means for Mountain Center roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
