North winds gusting up to 45 mph could down tree limbs and knock out power across the Ventura County mountains near Camarillo and Moorpark starting the evening of Monday, Sept. 28.

The National Weather Service's Los Angeles/Oxnard office issued a Wind Advisory on Sunday, Sept. 27, at 1:15 p.m. The advisory takes effect at 6 p.m. Monday, Sept. 28, and runs through 6 a.m. Tuesday, Sept. 29.

The advisory covers the Northern Ventura County Mountains and Southern Ventura County Mountains, along with the Interstate 5 Corridor and several Santa Barbara County zones. Sustained north winds of 15 to 30 mph are expected, with gusts reaching 30 to 45 mph.

What residents should expect

The NWS warned that gusty winds will blow around unsecured objects and that tree limbs could come down. A few power outages may result. The agency urged residents to secure outdoor furniture, trash cans and other loose items before the wind picks up.

Driving conditions could also deteriorate. The NWS cautioned that winds this strong can make driving difficult, especially for high-profile vehicles such as trucks, buses and trailers. The agency noted that a single strong gust can be enough to flip a trailer on its side, as the San Bernardino Sun reported. Motorists should keep extra distance from large vehicles on the road.

What's behind the wind

A KEYT forecast attributed the event to a low-pressure system pushing inland to the north, creating a moderate northerly flow. Gusts could be strongest below passes and canyons, the forecast noted.

The region is also dealing with ocean effects from Hurricanes Odalys and Polo. A separate High Surf Advisory remains in effect through Tuesday for much of Southern California, including Ventura County. As we reported Sept. 27, 7-foot surf and flood advisories were already affecting Ventura County beaches.

If the power goes out

During a prior wind event in October 2025, the Ventura County Sheriff's Office Camarillo Station reminded drivers that a flashing red or dead traffic signal must be treated as a stop sign under California law. That guidance still applies.

No power shutoff notices from Southern California Edison specific to this advisory had been posted as of the morning of Sept. 28. Residents can check real-time outage information at sce.com/outage or vcemergency.com.
