Corinne, UT Hail Storm – June 2026

Corinne, Utah, experienced late-afternoon hail on June 20, 2026, producing a peak hail size of 1.07 inches. The event produced multiple NWS warning areas and radar-detected hail along a compact late-afternoon to early-evening track.

What Happened

Storm activity began in the Corinne area in the late afternoon and concluded after nightfall. The National Weather Service issued nine alerts for the storm between 4:04 PM MDT and 7:43 PM MDT on June 20, 2026. Dual-polarization NEXRAD radar recorded hail signatures at 4:08 PM MDT (1.00 inch) and 4:49 PM MDT (0.89 inch). The remaining alerts carried NWS warning only guidance with hail size estimates of 0.75 inch issued at 4:04 PM MDT, 5:06 PM MDT, 5:35 PM MDT, 6:20 PM MDT, 6:37 PM MDT, 7:04 PM MDT, and 7:43 PM MDT. Alerts tracked a generally eastward progression across the Corinne metro footprint. The radar-detected returns and the sequence of NWS warning areas define where damaging hail was likely concentrated during the event.

Damage Assessment

Hail reached a maximum measured size of 1.07 inches during this event. Hail in the 0.75–1.07 inch range commonly produces dents to aluminum and thin steel panels. Automotive body panels parked outdoors in Corinne are at risk for door and hood denting and paint chipping. Windshields and sealed skylights may show pitting or stress cracks where impact angles concentrate force. Exposed rooftop features such as shallow-angle solar panels, HVAC condenser coils, and rolled roofing are vulnerable to surface abrasion and punctures. Asphalt shingles can sustain bruising and granule loss leading to reduced service life in the months after the event.

Field inspections in Corinne should prioritize vehicles parked without cover, south- and west-facing roof slopes that matched the storm track, and ground-mounted equipment left unsecured. Document photo evidence with timestamps and location tags to support insurance reviews and repair scopes.

What Contractors Should Know

Inspect roofs for granule loss, bruising, and cracked or split shingles. Start with accessible low-slope and high-exposure roof sections. Use binoculars or drone imaging where safe access is limited. Record exact GPS locations and time-stamped imagery. For residential claims, separate cosmetic dents from penetrative damage to determine repair versus replacement. For commercial clients, inspect rooftop equipment housings and rooftop membrane seams for impact damage.

For automobiles and small equipment, assess paint surface integrity and glass for micro-pitting. Provide estimates that itemize panel repair, paint blending, and glass replacement as applicable. Secure temporary coverings for exposed openings and advise property owners to avoid unscheduled tarping that could obscure pre-existing conditions. Maintain clear photographic logs and a timeline tied to the June 20, 2026 event for client records.
