Evidence / storm surfaces
How Genoa 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 19, 2026 — this storm produced no NEXRAD point detections over Genoa, so there is one map to show, not two.
The storm in context
Where Aug 19, 2026 sits in Genoa's hail record.
This was Genoa's 15th recorded hail day, arriving 1 day after the Aug 18, 2026 storm. By severity it ranks 13th of the 15 storms we have logged here. Radar put the day's largest stone over Genoa at 0.75" — radar-estimated size aloft.
The Aug 19, 2026 convective day was bigger than Genoa: the same system put hail over 496 other tracked cities, 30 of them in Colorado. Nearest: Arriba (15 miles northeast, up to 3.5"); Agate (30 miles northwest, up to 2"); Ramah (30 miles southwest, 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.
The National Weather Service logged no spotter reports for this storm over Genoa. 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 Genoa 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$120K
Potential roof exposure — 10 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.
