Quartzsite, AZ Hail Storm – September 2025

What Happened

A severe hail storm tracked through Quartzsite, AZ on September 18, 2025, producing 1-inch hail during a long afternoon-to-overnight sequence. The event carried multiple dual-polarization radar detections, with spotter-verified reports later confirming impacts across roads, vehicles, and utility lines.

The first hail alerts came at 11:45 AM MST and repeated through early afternoon at 12:29 PM, 12:35 PM, 12:48 PM, 1:10 PM, 1:16 PM, and 2:18 PM. Most of those alerts were radar-derived, while the 12:48 PM report added spotter verification. Later in the day, the storm remained organized enough to generate additional hail alerts at 5:47 PM and 6:08 PM with spotter input, then again at 7:48 PM and 8:04 PM on radar. A final warning-only alert was issued at 1:22 AM the next day.

Field reports showed the storm was not limited to hail. By 2:30 PM, Stallard Rd was closed because of flooding, and a highway department report at 2:39 PM described significant flooding in the area. In the evening, damage reports clustered around Quartzsite roadways and Interstate 8. A semi-truck overturned on I-8 just east of Bowker Rd at 6:08 PM, another truck was blown over near HWY 111 at 6:07 PM, and a third truck overturned at E Evan Hewes HWY and Bowker Rd at 6:20 PM. Power lines also came down near Bowker Rd and E Jasper Rd at 6:02 PM and along Dogwood Rd and E Aten Rd at 6:13 PM.

Damage Assessment

The field reports point to a storm that hit transportation corridors and utility infrastructure in more than one part of Quartzsite. Flooding shut down Stallard Rd and Cole Rd during the afternoon and evening. The reports place water over roads before and after the peak hail alerts, with timing estimated from radar in some cases. That pattern fits a storm with repeated passes and slow clearing.

The more disruptive impacts came from wind and roadway exposure. Multiple semi-truck rollovers were reported on and near Interstate 8, including locations just east of Bowker Rd and near HWY 111. Another rollover was reported at E Evan Hewes HWY and Bowker Rd. Those reports were paired with downed power lines near Bowker Rd and E Jasper Rd, and again near Dogwood Rd and E Aten Rd, where lines fell onto vehicles. The mix of overturned trucks, downed conductors, and roadway closures suggests the storm affected a broader corridor than a single hail core.

The hail reports themselves stayed at the 1-inch mark, but the verified surface reports show the event produced more than hail-only impacts. Road flooding, utility damage, and vehicle losses were documented in separate parts of the Quartzsite area through late afternoon and evening.

What Contractors Should Know

Quartzsite sits on a set of roadways that matter to restoration work. Interstate 8, HWY 111, Bowker Rd, E Jasper Rd, Dogwood Rd, and E Aten Rd all appear in the field reports from this storm. Crews working this event should start with access control, then move to utility and transport damage before roof-level inspections. Road closures and truck rollovers can slow mobilization on the east side of town and along the interstate corridor.
