Evidence / storm surfaces
How Arriba saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Sep 19, 2026 — this storm produced no NEXRAD point detections over Arriba, so there is one map to show, not two.
The storm in context
Where Sep 19, 2026 sits in Arriba's hail record.
This was Arriba's 16th recorded hail day, arriving 14 days after the Sep 5, 2026 storm. By severity it ranks 4th of the 16 storms we have logged here. Radar put the day's largest stone over Arriba at 2.25" — radar-estimated size aloft.
The Sep 19, 2026 convective day was bigger than Arriba: the same system put hail over 336 other tracked cities, 27 of them in Colorado. Nearest: Flagler (11 miles east, up to 2.75"); Hugo (11 miles south, up to 2.25"); Genoa (13 miles west, up to 2.25").

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.
For this storm over Arriba, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Severe hail signal
What 2.25" hail means for Arriba roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$4.9M
Potential roof exposure — 405 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 405 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
September 2028
Claims from this storm can typically be filed until around September 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 $85 on top of the $150 plan.
