Los Alamos, NM Hail Storm – July 2026

Los Alamos, NM recorded radar-detected hail on July 27, 2026, concluding that evening. Peak hail reached 1.78 inches and produced multiple dual-polarization radar alerts.

What Happened

The storm developed over northern New Mexico and moved across Los Alamos County on July 27. Dual-polarization NEXRAD issued two hail alerts tied to the event. The first alert was issued at 3:04 PM MDT for radar-detected 1.00-inch hail during mid-afternoon. The second alert arrived at 5:15 PM MDT for radar-detected 1.27-inch hail in the early evening. Local radar returns later mapped a maximum hail measurement of 1.78 inches within the aggregated zones. The event is concluded and no active warnings remain for the area.

Damage Assessment

Hail up to 1.78 inches poses a defined risk to common residential and vehicular materials found in Los Alamos. Vehicles parked in exposed locations and on ridge-top streets are susceptible to denting and paint damage. Properties with older asphalt shingles may show accelerated granule loss and isolated shingle fracture on windward slopes. Solar collectors and skylights that lack impact-rated glazing face elevated risk of cracking when struck at peak sizes. Ground-level landscaping and gutters experienced localized impacts but widespread tree uprooting or structural collapse is not expected from this size range.

Reported risk concentrates on higher-elevation and exposed properties above downtown Los Alamos and along county road corridors where terrain funnels storm cores. Inspect roofs and siding for granule loss, bruising, and punctures. Photograph visible damage and note locations for claims and contractor estimates.

What Contractors Should Know

Assessments should start with a perimeter inspection and documented photos tagged with location and time. Prioritize roofs with aged asphalt shingles and visible granule depletion. For solar arrays, identify cracked panels and loosened mounts. Use ladder and harness protocols appropriate for steep or elevated sites in Los Alamos. Record evidence before repairs begin to support insurance processes.

Repair crews should plan for staged work. Triage high-exposure homes and municipal facilities first. Prepare materials for common outcomes tied to this hail range: shingle replacement, cosmetic vehicle repairs, localized gutter and skylight replacement, and isolated solar module swaps. Confirm impact-rated replacements where owners request upgraded materials. Coordinate with insurers on scope and sequencing to reduce duplicate work and site re-visits.
