Flagler, CO Hail Storm – July 2026

Flagler, Colorado experienced large hail on July 3, 2026, with a peak measured particle of 4.2 inches. The multi-alert late-evening storm produced repeated radar hail detections and NWS warnings before concluding in the early hours of July 4.

What Happened

Twelve NWS alerts covered the Flagler metro area between 7:20 PM MDT on July 3 and 2:12 AM MDT on July 4. The sequence alternated between NWS warnings and radar-detected hail reports. Key alerts:

• July 3 · 7:20 PM MDT (01:20 UTC) – 1.5 inch hail – NWS warning only.
• July 3 · 11:21 PM MDT (05:21 UTC) – 1.79 inch hail – dual-polarization radar detection.
• July 3 · 11:36 PM MDT (05:36 UTC) – 1.63 inch hail – dual-polarization radar detection.
• July 3 · 11:48 PM MDT (05:48 UTC) – 1.5 inch hail – dual-polarization radar detection.
• July 3 · 11:52 PM MDT (05:52 UTC) – 2.39 inch hail – dual-polarization radar detection.
• July 3 · 11:55 PM MDT (05:55 UTC) – 2.89 inch hail – dual-polarization radar detection.
• July 4 · 12:10 AM MDT (06:10 UTC) – 2.48 inch hail – dual-polarization radar detection.
• July 4 · 12:30 AM MDT (06:30 UTC) – 3.31 inch hail – dual-polarization radar detection.
• July 4 · 12:44 AM MDT (06:44 UTC) – 2.49 inch hail – dual-polarization radar detection.
• July 4 · 1:07 AM MDT (07:07 UTC) – 2.08 inch hail – dual-polarization radar detection.
• July 4 · 1:31 AM MDT (07:31 UTC) – 0.84 inch hail – dual-polarization radar detection.
• July 4 · 2:12 AM MDT (08:12 UTC) – 0.75 inch hail – NWS warning only.

Radar detections account for the majority of alerts from late night into early morning. Two alerts were issued on NWS warning-only basis without concurrent radar-derived hail size in the automated feed.

Damage Assessment

Alerted hail sizes reported by radar ranged from 0.75 to 3.31 inches across the Flagler metro. Hail in the 2.0–3.5 inch range risks significant impact to vehicles, roofing shingles, skylights, and exposed mechanical equipment. Lighter detections under 1 inch indicate cosmetic damage to siding, screens, and soft landscaping.

For Flagler properties, expect denting to vehicle panels and potential shingle granule loss where hail fell at 2 inches or greater. Agricultural losses are likely for unprotected high-value crops in the immediate hail path. Photographic documentation dated to July 3–4 will support any claims or repair prioritization.

What Contractors Should Know

Inspect roofs first for impact patterns, granule loss, and punctures. Check vents, skylights, gutters, and flashing for fractures that can lead to water intrusion. Prioritize temporary tarps over active leaks and photo each stage of work with a location and timestamp.
