Ajo, AZ Hail Storm – October 2026

Ajo, AZ recorded hail up to 2.71 inches on October 10, 2026, during a short-lived severe thunderstorm in the early evening. The event concluded the same night after producing a concentrated radar hail core over the Ajo metro.

What Happened

The storm moved through Ajo in the early evening. The National Weather Service issued two severe thunderstorm warnings for the area at 7:12 PM MST (02:12 UTC) and 9:52 PM MST (04:52 UTC). Both alert entries were NWS warning only with no hail size included in the warning text. Dual-polarization radar detected a compact hail core during the later warning period and produced the event's maximum radar-derived hail diameter. The system weakened and the event was declared concluded before midnight local time.

Damage Assessment

Hail of this diameter can puncture roof coverings and strip granules from asphalt shingles, increasing leak potential for older roofs. Metal roofs and siding may show denting and cosmetic deformation. Vehicle body panels and single-pane glass are at risk of dents and breakage, particularly for cars stored outdoors. Rooftop equipment such as HVAC units and solar arrays can incur panel cracking, bent mounts, and torn flashing when struck by large hail.

Concentrated impacts are most likely where the radar hail core passed over the Ajo metro. Inspections should prioritize older roofing systems, exposed vehicles, and rooftop-mounted systems in the core area. Photograph all damaged components with oblique and overhead views and record GPS coordinates for each observation.

What Contractors Should Know

Do a safety-first walk-through before starting repairs. Secure any broken glass and loose debris to prevent secondary damage. Apply temporary tarps to compromised roof sections to limit interior water entry. For solar arrays, isolate and document any cracked modules; follow manufacturer guidance before re-energizing affected circuits.

Document damage with time-stamped photos, clear GPS coordinates, and short notes on material condition. Collect representative samples of shingle loss for insurance estimates and quantify replacement area in square feet. Order tarps and critical materials immediately; coordinate start dates and scope with property owners and adjust estimates for potential permitting or supply delays.
