St. David, AZ Hail Storm – August 2026

St. David, AZ experienced a concluded hail-producing storm on August 30, 2026, producing peak hail of 1.12 inches and prompting a sequence of NWS alerts and radar detections.

What Happened

The event began in the late evening on August 30. The National Weather Service issued an initial warning at 9:39 PM MST that covered the local warning area; that alert was issued as a warning only and did not include radar-sized hail estimates. A later NWS alert at 3:09 AM MST on August 31 followed dual-polarization NEXRAD hail detection within the same multi-zone aggregate report. Radar returns indicated a concentrated hail track through the St. David metro during the overnight period. The storm is concluded and no further warnings are active for this event.

Damage Assessment

Measured peak hail reached 1.12 inches during the event. Hail at this scale is slightly larger than a US quarter and is capable of causing vehicle panel dents, chips to exterior paint, and localized damage to asphalt shingle edges and older siding in exposed locations. Landscape and soft materials such as potted plants, patio furniture cushions, and glass skylights are vulnerable in unprotected areas.

There were no field reports attached to this multi-zone aggregate record indicating large-scale structural collapse or widespread catastrophic failure. Property owners inside the NWS warning area should document exterior damage with date-stamped photos, record vehicle locations during the event if available, and preserve intact samples of roofing or siding for insurer inspection where applicable.

What Contractors Should Know

Inspect roofs first for impact bruising, fractured shingles, and granule loss along windward edges. Check metal flashings, gutters, and HVAC condenser coils for dents and perforations. For vehicles, photographic documentation of dents and paint chips is important prior to any repair work. Prioritize temporary weatherproofing for exposed areas and secure loose exterior materials to prevent secondary water intrusion during subsequent storms.

Estimate conservatively for material replacement when granule loss or shingle cracking is evident. Record exact addresses within the NWS warning area and note whether properties fall inside the radar-detected hail track when creating scopes of work. Provide itemized invoices separating inspection, temporary repair, and full replacement line items to streamline insurance submissions.
