Rifle, CO Hail Storm – May 2026

Rifle, Colorado experienced a multi-zone hail event on May 17, 2026, with a measured 4.33-inch hailstone recorded in the metro area. The storm produced a sequence of NWS radar-detected hail alerts through the late morning and early afternoon.

What Happened

NWS issued five separate hail alerts across the Rifle warning area between 12:30 PM MDT and 2:07 PM MDT. The sequence recorded by NEXRAD dual-polarization hail detection was:

• May 17 · 12:30 PM MDT (18:30 UTC) – 0.75-inch hail detected in the warning area.
• May 17 · 12:59 PM MDT (18:59 UTC) – 0.88-inch hail detected in the warning area.
• May 17 · 1:21 PM MDT (19:21 UTC) – 0.75-inch hail detected in the warning area.
• May 17 · 1:33 PM MDT (19:33 UTC) – 0.75-inch hail detected in the warning area.
• May 17 · 2:07 PM MDT (20:07 UTC) – 1.00-inch hail detected in the warning area.

The alerts indicate multiple cells or a multicell complex traversing the metro. Radar-based detections showed consistent 0.75-inch signatures with a later pulse registering near 1.00 inch over parts of the NWS alert area. A large hailstone was measured on the ground within the Rifle metro, and the event is recorded as concluded in the early afternoon.

Damage Assessment

Radar detections of 0.75–1.00-inch hail across the NWS alert area suggest common cosmetic damage to vehicles, denting to metal panels, and localized breakage of glazing on exposed skylights and glass doors within Rifle. The measured large hailstone in the metro carries a higher risk profile: it can fracture asphalt shingles, compromise weaker siding, and cause concentrated impact damage to automobiles and rooftop equipment where the stone fell.

Field reports tied to this event indicate vehicle denting and broken irrigation equipment in residential sections of the metro. Roof inspections in the directly affected neighborhoods should expect isolated to widespread shingle loss on older or weathered roofs and localized perforation of vinyl soffits where impact points are concentrated.

What Contractors Should Know

Prioritize safety and documentation on initial visits. Photograph impact locations with scale, record GPS coordinates or street-level addresses, and note roof orientation and elevation of impacts. Inspect roof coverings, skylights, HVAC pads, and exterior mechanical enclosures first. Where large, localized blows exist, probe for underlying membrane or decking damage before recommending full reroofing.

For emergency repairs, secure tarping and temporary covers rated for UV exposure and wind load. Tarping should be fastened to structural members where possible, not only to shingles. Provide clear line-item estimates separating temporary mitigation from permanent replacement so property owners and insurers can distinguish immediate stabilization from long-term repairs.
