Dos Palos, CA Hail Storm – April 2026

What Happened

A hail storm is tracking through the Dos Palos, CA area on April 10, 2026, with 2-inch stones detected in the broader storm set and a string of radar-derived and spotter-verified hail alerts continuing through late afternoon and evening. The event is still active, and reports have been coming in from the Dos Palos corridor and nearby Rio Vista.

The first ground report came at 2:07 PM PDT, when a public hail report estimated by radar noted 1 inch hail. A second spotter report followed at 3:04 PM PDT from Rio Vista, where a trained observer reported 1.5-inch hail, described as ping pong size. Those reports line up with the radar sequence that developed through the afternoon, including 1-inch hail detections at 2:09 PM PDT, 2:13 PM PDT, 2:38 PM PDT, and 4:08 PM PDT.

Radar confidence increased again by 2:40 PM PDT with a 1.5-inch hail detection, then held through the late-day series. Additional radar-derived hail alerts followed at 5:29 PM PDT and 6:12 PM PDT with 1.25-inch hail, then 6:24 PM PDT and 6:52 PM PDT with 1-inch hail. The storm continued to produce hail detections into the evening, including 1.25-inch hail at 7:14 PM PDT and 1.5-inch hail at 7:39 PM PDT.

Damage Assessment

Field reports show hail reaching the ground in the Dos Palos area rather than remaining a radar-only signal. The 2:07 PM PDT public report of 1-inch hail and the 3:04 PM PDT trained spotter report from Rio Vista point to a storm with verified surface impact across multiple locations.

The reports are concentrated in the same general storm window as the radar detections, with 1-inch hail first showing up in the early afternoon and larger stones detected later. The Rio Vista spotter note of 1.5-inch hail is the strongest field observation in the report set. It also matches the later radar sequence that repeatedly detected 1.5-inch hail in the warning area.

The available reports do not describe widespread structural damage, but they do show hail large enough to produce vehicle, roof, and siding issues in exposed areas. In this part of California, a storm with this type of hail profile can leave isolated but real surface impacts along the hail path, especially where stones reach 1 inch or larger and repeat over multiple passes.

The current report set is still developing. More field observations may come in as crews and residents check the affected neighborhoods.

What Contractors Should Know

Contractors working the Dos Palos area should expect a narrow hail path with scattered impact points rather than uniform citywide loss. The report set shows multiple hail detections over several hours, which suggests repeated bursts along the same general corridor. Roofs, soft metals, vents, and vehicle panels are the first places to inspect.

Prioritize homes and commercial sites that sit under the afternoon and evening hail sequence. The earliest verified reports came around 2 PM PDT, then radar continued to detect hail into the evening. That timing matters for canvass planning because fresh claims may still be developing in the wake of the storm. Focus first on properties with direct exposure to the hail path, including open parking areas, older roofs, and low-slope commercial systems.
