Hanna, WY Hail Storm – June 2026

Hanna, WY experienced radar-detected hail on June 20, 2026, peaking at 1.83 inches in the late afternoon. The storm produced a sequence of NWS alerts across the town and nearby rural areas and has concluded.

What Happened

The event began in mid-afternoon and continued into early evening. Six NWS alerts were issued for the Hanna area on June 20. Alerts recorded at 2:40 PM, 3:25 PM, and 4:41 PM cited radar-detected hail signatures from dual-polarization NEXRAD. A 5:25 PM radar-detected alert reported the peak radar-derived signature at 1.83 inches. Two later alerts at 5:27 PM and 6:26 PM were issued as NWS warning-only reports without separate radar hail-size signatures.

The alerts tracked a storm cluster that moved across town and adjacent agricultural land in a generally east-northeast direction. Radar-derived hail indications appeared in multiple passes, producing repeated hail signatures over parts of Hanna rather than a single isolated cell. The NWS warning area covered the broad path of the storm; the radar-derived detections show where hail signatures were strongest.

Damage Assessment

Hail signatures reported during the storm ranged from smaller pebble sizes to the peak radar-derived signature above one and three-quarter inches. Hail in that upper range commonly produces denting to vehicle body panels and can fracture lighter glass. In Hanna, the storm crossed residential blocks and areas with parked farm equipment. Roof surfaces with older asphalt shingles and metal panels are at elevated risk for shingle granule loss, dents, and potential leaks when exposed to repeated hail impacts like those observed during the late-afternoon passes.

There were no spotter-verified damage reports included in the NWS alerts for this event. Field inspection is necessary to determine actual loss. Photographs of affected vehicles, roofs, and skylights will establish scope and timing for claims. Document locations in Hanna precisely; hail impacts from this storm were not uniform across the entire NWS warning area.

What Contractors Should Know

Plan an on-site assessment focused on residential roofs, vehicle fleets, and exposed farm equipment in the areas radar indicated repeated hail returns. Start with a visual exterior inspection for dent patterns on metal, cracked glazing, and displaced or missing shingle granules. Use handheld cameras with time-stamped images and record GPS coordinates for each damaged item or roof section. Prioritize structures with older roofing material where repeated impacts are likely to have accelerated wear.

For roofing repairs, expect to recommend replacement rather than spot patching where multiple shingle blows or granule loss is evident. For vehicle and equipment fleets, document panel dents and paint damage for panel-beating or repaint estimates. Coordinate with property owners on temporary waterproofing if inspections reveal compromised roof integrity.
