Trinchera, CO Hail Storm – August 2026

Trinchera, CO experienced a concluded hail event on August 14, 2026, with a peak hail size of 2.33 inches. The storm produced multiple NWS warning polygons and radar-detected hail returns across the metro area.

What Happened

This is a multi-zone aggregate report for the Trinchera metro. NWS issued eight alerts from mid-afternoon into the late evening, spanning 2:44 PM MDT through 10:02 PM MDT. Two alerts included dual-polarization radar detections at 3:19 PM MDT and 5:54 PM MDT. The remaining alerts were NWS warning only products issued at 2:44 PM, 3:48 PM, 4:09 PM, 5:02 PM, 9:40 PM, and 10:02 PM MDT.

Reported hail sizes in the alert stream ranged from three-quarters of an inch to just over one inch for the radar-detected and warning-only products. Radar-derived returns flagged concentrated hail swaths in the afternoon and again in the early evening. The aggregated dataset for this event indicates a maximum measured hail diameter of 2.33 inches within the metro footprint.

Damage Assessment

Hail sizes recorded in the alert sequence and radar returns indicate a mix of small to large hail across Trinchera neighborhoods. Hail in the 0.75–1.06 inch range commonly produces dents in vehicle body panels and can abrade or notch asphalt shingles. Hail at the 2.33 inch peak is large enough to crack skylights, shatter single-pane glass, and cause localized structural roof damage on older or weathered coverings.

No field-verified damage reports are embedded in this public aggregate. Where radar-detected returns were strongest, prioritize inspections of vehicles parked outdoors, exposed HVAC equipment, skylights, solar arrays, and roof coverings. Photographic documentation should capture scale and location relative to known landmarks or addresses.

What Contractors Should Know

First response should focus on safety and rapid triage. Document access routes and park vehicles off streets where possible to avoid secondary damage. For roofing teams, prioritize visible punctures, displaced shingles, and cracked flashings. Use a 2.33-inch reference object in photographs when documenting larger hail impacts. For smaller hail signatures, look for dent clusters on metal edging, gutters, and vehicle panels.

For claims and repair work, maintain time-stamped photos and a short site log noting visible damage, latitude/longitude or address, and the local time of inspection. Temporary coverings are appropriate for open penetrations and broken skylights. Coordinate with property owners about obtaining insurance contact information before starting non-emergency repairs.
