A powerful storm system brought gusty winds and flood risks to Southern California on Thursday, generating a rotating dust column near Victorville and prompting multiple weather alerts. Investigators concluded that straight-line winds were the more likely cause of damage, with the strongest gusts around 36 mph. In San Clemente, wind damage at the municipal golf course spurred cleanup efforts and raised questions about a possible tornado, though forecasters cited a low probability. The region faced a mix of thunderstorms, floods, and warnings that varied by location, with expectations of clearing by the evening and drier conditions to follow on Friday. Authorities continued monitoring for potential tornado activity as the system moved through the area.

In Victorville, a motorist captured video of a rotating dust cloud near US Route 395 and Dos Palmas Road, with loose debris swept into the air as the column spun near the ground. A Wind Advisory was in effect, but no injuries were reported from the incident.
The phenomenon was identified by experts as a gustnado, a type of whirlwind forming along the edge of thunderstorm outflows, though officials later assessed straight-line winds as the likelier cause of the observed damage.
San Clemente Municipal Golf Course suffered wind-related damage, prompting crews to clear fallen trees and debris from the 150 E. Avenida Magdalena site amid the storm’s downstream effects.
Forecasters warned of a broad set of hazards, including Flood Advisories, Flash Flood Warnings, and Severe Thunderstorm Warnings, with conditions varying by location across Southern California during the system’s passage.
The National Weather Service noted a very small tornado risk but emphasized heavy rain, thunderstorms, and powerful gusts as the primary threats, complicating the potential for localized damage.
Despite the gusty activity, weather officials anticipated the storm to move out by Thursday evening, followed by drier conditions expected on Friday across the region.
An Orange County investigation kept a close watch on the possibility of a tornado tied to the system, though current findings remained inconclusive as officials reviewed reports from the impacted areas.
