Evidence / storm surfaces
How Los Alamos 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 Jul 27, 2026 — this storm produced no NEXRAD point detections over Los Alamos, so there is one map to show, not two.
The storm in context
Where Jul 27, 2026 sits in Los Alamos's hail record.
This was Los Alamos's 5th recorded hail day, arriving 3 days after the Jul 24, 2026 storm. By severity it ranks 2nd of the 8 storms we have logged here. Radar put the day's largest stone over Los Alamos at 0.75" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Los Alamos: the same system put hail over 803 other tracked cities, 17 of them in New Mexico. Nearest: Pena Blanca (14 miles south, up to 0.5"); Jemez Springs (17 miles west, up to 0.5"); Rociada (45 miles east, 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.
No ground reports were filed with the National Weather Service for this storm over Los Alamos. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Near the severe threshold
What 0.75" hail means for Los Alamos 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
$9.4M
Potential roof exposure — 784 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 4 jobs
- Illustrative work
- ~$60K
Close just 0.5% of the 784 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
July 2028
Claims from this storm can typically be filed until around July 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 $165 on top of the $150 plan.
