Evidence / storm surfaces
How Topawa 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 Aug 19, 2026 — this storm produced no NEXRAD point detections over Topawa, so there is one map to show, not two.
The storm in context
Where Aug 19, 2026 sits in Topawa's hail record.
This was Topawa's 2nd recorded hail day, arriving 16 days after the Aug 3, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Topawa at 1.75" — radar-estimated size aloft.
The Aug 19, 2026 convective day was bigger than Topawa: the same system put hail over 496 other tracked cities, 25 of them in Arizona. Nearest: Sells (8 miles northeast, up to 2"); Sahuarita (34 miles east, up to 0.75"); Rio Rico (50 miles east, up to 1.5").

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.
Nobody on the ground filed a report over Topawa 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.
High damage potential
What 1.75" hail means for Topawa roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$708K
Potential roof exposure — 59 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
August 2028
Claims from this storm can typically be filed until around August 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
