Evidence / storm surfaces
How Rio Rico saw the hail — from two instruments
Aug 3, 2026 · Rio Rico, AZ
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.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size Surface resolved
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.

The storm in context
Where Aug 3, 2026 sits in Rio Rico's hail record.
This was Rio Rico's 4th recorded hail day, arriving 19 days after the Jul 15, 2026 storm. By severity it ranks 6th of the 9 storms we have logged here. Radar put the day's largest stone over Rio Rico at 1" — radar-estimated size aloft.
The Aug 3, 2026 convective day was bigger than Rio Rico: the same system put hail over 172 other tracked cities, 17 of them in Arizona. Nearest: Nogales (10 miles south, up to 1"); Elgin (26 miles northeast, up to 1"); Huachuca City (40 miles east, up to 0.75").
These maps are stills. In the app this date is one of 9 Rio Rico 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
1 report filed with the NWS
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.

How the storm moved
Timing and place names from NOAA ground reports
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Nogales — beyond Rio Rico itself.
Damage-capable hail signal
What 1" hail means for Rio Rico 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.

Roofing exposure
What this storm is worth to a roofer.
9 homes × $12,000 avg. claim
Potential roof exposure
$108K
Potential roof exposure — 9 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.
Names and phones for every home in the footprint: at most $2 on top of the $150 plan.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 10, 2026.
