Hasty, CO Hail Storm – May 2026

Hasty, CO experienced a multi-zone hail event on May 21, 2026, producing up to 2 inches of hail and a series of radar-detected and NWS warning-only alerts. The storm concluded after an 11-alert sequence that moved across the local NWS warning area in late afternoon and early evening.

What Happened

The event began in mid-afternoon with the first alert at 2:51 PM MDT and continued through early evening, ending with the final alert at 6:25 PM MDT. Eleven NWS alerts were issued for the Hasty metro area. Dual-polarization radar detected multiple hail signatures at different times, and several alerts were issued on NWS warning-only basis without matching radar-derived hail sizes.

Notable radar-detected alerts included 1.2 inches at 2:51 PM MDT, 1.31 inches at 4:16 PM MDT, and 1.54 inches at 4:21 PM MDT. Later radar-derived signatures recorded 1.44 inches at 6:14 PM MDT and 1.42 inches at 6:25 PM MDT. NWS warning-only alerts were issued at 3:59 PM MDT, 5:14 PM MDT, and 5:57 PM MDT. The alert sequence produced overlapping coverage across multiple notification zones within the warning area.

The dataset for this multi-zone page aggregates those eleven alerts into a single event summary for Hasty and nearby notification zones. Radar-detected signatures and NWS warning polygons indicate the storm tracked generally from west to east across the warning area during the late afternoon window.

Damage Assessment

Radar-detected hail signatures larger than one inch were present across segments of the warning area during the late-afternoon to early-evening window. Addresses and assets located inside the NWS warning area while those signatures passed were exposed to hail capable of causing exterior impact damage.

No centralized public damage report is appended to this aggregate page. Contractors and adjusters should expect variable exposure across short distances where radar-detected signatures and NWS warning polygons overlapped. Vehicles, outdoor equipment, and unshielded rooftop coverings in the affected notification zones had the highest exposure during the alert window.

What Contractors Should Know

Plan inspections by overlaying the NWS warning area and the local notification zones that received radar-detected alerts. Prioritize inspections for properties that were within the warning polygons between 4:00 PM MDT and 6:30 PM MDT, when the most significant radar-derived hail signatures occurred. Document pre-existing conditions with timestamped photos. Note the specific alert times and sizes observed at each location to support claims and estimates.

Use a targeted sampling approach. Inspect representative roof slopes, exterior trim, and parked vehicles at multiple addresses rather than treating the entire warning area as uniformly affected. Record GPS locations for all observed damage and collect occupant statements with local times. Maintain safety protocols for ladder work and loose debris removal.
