Elmo, UT Hail Storm – September 2026

Elmo, UT recorded a late-afternoon severe hail event on September 16, 2026, producing a peak hail diameter of 2.33 in as the storm moved across the metro. The system produced multiple radar hail returns and has concluded.

What Happened

The storm moved through Elmo in late afternoon into early evening on September 16, 2026. The National Weather Service issued two severe-hail alerts tied to the same convective cell. The first alert was issued at 2:29 PM MDT and noted a radar-detected 1.00 in hail signature. A second alert followed at 3:52 PM MDT with a radar-detected 1.43 in signature. Dual-polarization NEXRAD returns showed evolving hail cores as the cell intensified and translated east-southeast across the metro. Post-event radar analysis and ground cross-checks identified a maximum hail diameter of 2.33 in within the storm track. The storm is concluded and no active warnings remain for the area.

Damage Assessment

Radar data indicate hail ranged from approximately 1.00 in to 2.33 in across parts of Elmo. Hail at the lower end of that range commonly produces dents to vehicle body panels and chipped paint on outdoor equipment in exposed locations. Hail in the 1.75–2.33 in range has sufficient mass to fracture or puncture composite roofing shingles, damage skylights, and break glass when wind-driven into exposed openings. Localized concentrations of larger hail were most likely where the radar cores aligned with the central metro footprint. Municipal infrastructure such as street-level signage, uncovered HVAC units, and small solar panels in the direct path should be inspected for impact damage.

What Contractors Should Know

Prioritize roof and vehicle assessments in neighborhoods along the reported storm translation path through central and eastern Elmo. Start with visual exterior inspections from ground level and documented photographs before any access. Look for missing or fractured shingles, concentrated granule loss, dent patterns on metal trim, and cracked skylights. Record GPS-referenced photos and note the nearest NWS alert times when filing estimates.

When exterior conditions allow, perform a careful attic inspection to detect granular debris and light entry points that indicate compromised shingles. For property owners with visible impact, provide immediate temporary coverings where openings exist and schedule detailed moisture intrusion checks within 48–72 hours. Coordinate with property managers and insurers on scope and sequencing to avoid duplicate work and meet documentation requirements for claims.
