Glen St. Mary, FL Hail Storm – August 2026

Glen St. Mary, Florida experienced a concluded hail event late afternoon into early evening on August 24, 2026, producing stones up to 1.3 inches and multiple NWS warning polygons across the metro area.

What Happened

NWS issued eight warning polygons between 3:55 PM and 6:14 PM EDT for potential 0.75-inch hail. The alerts and local times were: 3:55 PM, 4:23 PM, 4:55 PM, 5:00 PM, 5:19 PM, 5:26 PM, 5:56 PM, and 6:14 PM EDT. Each advisory carried NWS warning-only language indicating a hail threat centered on 0.75-inch stones. Aggregated field reports and post-event review show larger stones occurred at limited locations within the warning area.

Radar indicated strong reflectivity cores crossing the Glen St. Mary metro during the late afternoon. Dual-polarization returns flagged hail-sized signatures during the peak window. Most warning polygons tracked a northeastward progression across the local grid. The event concluded by early evening with no further NWS activity after 6:14 PM EDT.

Damage Assessment

Most warnings in this sequence targeted 0.75-inch hail. Hail of that size commonly causes minor cosmetic damage to vehicle paint, windshield pitting, and small dents on unsheltered metal surfaces. A smaller subset of the storm produced stones up to 1.3 inches in diameter. Stones of that diameter increase the probability of cosmetic panel dents, cracked sunroofs, and localized asphalt shingle granule loss where exposure was direct.

Roofing and automotive surfaces directly exposed in the warning area are the highest risk. Trees and soft landscaping may show shredded foliage and punctures consistent with the larger stones. Expect variability across short distances; damage will concentrate where stronger cores crossed and where ground exposure was unobstructed.

What Contractors Should Know

Inspect priority locations inside the NWS warning areas issued between 3:55 PM and 6:14 PM EDT on August 24, 2026. Start with vehicles stored outdoors, residential single-family roofs, and commercial flat roofs along the northeastern track of the warnings. Measure hail impressions where present and photograph a currency item or ruler adjacent to the impression for scale. Use the NWS warning polygons as an initial triage map, then refine routes based on observed damage density.

Document storm timing and local conditions on each job file. Note that most warnings targeted 0.75-inch hail, with isolated larger stones reported. For roofing, check for granule loss, split seals around roof penetrations, and impact dimples on shingles. For vehicle work, prioritize cracked glass and door or hood dents that penetrate paint. Preserve samples and timestamps for adjuster reviews and consider temporary tarping only where secondary water intrusion is likely.
