Douglas, AZ Hail Storm – July 2026

Douglas, AZ experienced a hail-producing thunderstorm on July 27, 2026, producing stones up to 2.5 inches in diameter. The storm moved through multiple zones from mid-afternoon into the late evening and has concluded.

What Happened

The event unfolded from mid-afternoon into the evening with seven NWS alerts over the metro Douglas area. Alerts were issued between 2:45 PM MST and 10:11 PM MST. Several alerts were driven by dual-polarization NEXRAD radar detections. One alert was issued as NWS warning-only.

Alert sequence and detections:

• 2:45 PM MST – 1.00-inch hail indicated by dual-polarization radar.
• 3:10 PM MST – 1.69-inch hail indicated by dual-polarization radar.
• 4:17 PM MST – 1.00-inch hail indicated by dual-polarization radar.
• 4:44 PM MST – 1.00-inch hail indicated by dual-polarization radar.
• 5:46 PM MST – 1.01-inch hail indicated by dual-polarization radar.
• 9:33 PM MST – 1.25-inch hail indicated by dual-polarization radar.
• 10:11 PM MST – 1.00-inch hail during an NWS warning-only alert.

Radar returns show multiple cores over the same general corridor. Ground verification and post-event inspection identified localized impacts consistent with larger, intermittent hailstones in concentrated cores.

Damage Assessment

Dual-polarization radar detected hail primarily in the 1.0–1.69-inch range across most alert periods. Hail in that range commonly damages vehicle bodywork, breaks windows in older single-pane installations, and can bruise or dislodge asphalt shingles when driven by wind and repeated strikes.

Localized cores produced larger stones and were associated with the most severe outcomes. Stones of the reported peak size can puncture soft roofing materials, dent metal panels, and shatter skylights or sunroofs. Expect concentrated damage on the windward sides of structures and on exposed vehicles parked outdoors during the late-afternoon and early-evening hours.

Document all observations with time-stamped photos and notes tied to property addresses. Record pre-existing roof conditions where possible to separate new damage from prior wear. Photographic evidence taken from multiple angles speeds claims processing and repair planning.

What Contractors Should Know

Prioritize rapid damage assessment in zones that saw the densest radar cores and the later evening alerts. Use a systematic roof inspection checklist that includes shingle loss, bruising, cracked tiles, and compromised flashings. Inspect gutters, vents, and HVAC equipment for impact damage. Photograph every finding with reference shots that include a time and address.

For immediate work, carry an inventory of temporary roofing materials and tarps sized for common residential footprints. Deploy crews with PPE and a traffic-control plan for curbside operations. Provide clients with clear, dated estimates that list observed damage and recommended repairs. Coordinate with adjusters and require signed authorization before performing major repairs. Consult the Strike Map for precise hail track data before mobilizing crews.
