LOS ANGELES, CA — The National Weather Service has issued a red flag warning for parts of Los Angeles and Ventura counties as Santa Ana winds push back into Southern California on Saturday.
Forecasters say the strongest gusts are expected to begin around 2 a.m. and last until 6 p.m. later in the day. The combination of low humidity and hot temperatures is expected to create dangerous wildfire conditions, and any fire that starts could spread quickly.
Officials are urging residents to avoid anything that could spark flames, review evacuation plans and stay alert to their surroundings as the wind event develops.
Forecasters expect the highest risk during Saturday’s wind window
The warning covers a period when winds, dry air and heat are all expected to line up at once. That combination is especially concerning in fire-prone areas, where even a small ignition can become a fast-moving blaze.
The National Weather Service said isolated downed trees and power outages are also possible in both counties. Those impacts could create hazards well beyond fire danger, especially if they affect roads, neighborhoods or emergency access.
Residents are being told to prepare now rather than wait until conditions worsen. That includes understanding escape routes, checking on supplies and being ready for sudden changes if the winds intensify.
County officials warn of outages that could interrupt daily services
Los Angeles County officials are also warning people to prepare for public safety power shutoffs on Saturday, along with unplanned outages caused by wind damage. Those outages can reach far beyond lights going out at home.
Officials say disruptions could affect communications, traffic signals and medical equipment. That makes planning especially important for households and businesses that depend on electricity for safety or basic operations.
The warning comes as county agencies brace for wind-related impacts across the region. Residents in affected areas are being encouraged to stay informed and ready for interruptions that may develop with little notice.
Road restrictions are planned for Topanga Canyon during the warning
Caltrans, the Los Angeles County Sheriff’s Department and Public Works are planning access restrictions on Mulholland Highway and Pacific Coast Highway through Topanga Canyon Boulevard during the red flag warning.
Only residents will be allowed through the affected area while the warning remains in effect. The move is meant to reduce risk and keep the corridor controlled during dangerous wind conditions.
Travelers in the region may need to adjust routes and allow extra time if they were planning to move through the canyon. The restrictions add another layer of caution to a weekend already shaped by fire weather concerns.
Fire crews have added staffing and staged equipment across the county
Los Angeles County Fire Chief Anthony C. Marrone said the county fire department has increased staffing and positioned ground and aerial resources throughout Los Angeles County ahead of the heightened fire threat.
He said strong winds can drive rapid wildfire growth, which is why the county is moving resources into place before flames start. That preparation is aimed at improving response time if an ignition occurs.
The warning from fire officials underscores how seriously agencies are treating the weather pattern. With wind, heat and dry conditions all arriving together, crews are preparing for a scenario in which a fire could spread quickly and require immediate action.
Orange County also faces beach and coastal hazards this weekend
The weather concerns are not limited to inland fire danger. The National Weather Service also issued a coastal advisory for Orange County for the weekend.
In addition, a beach hazard statement is in effect for Los Angeles and Ventura counties. That means people heading to the coast may face dangerous conditions there as well, even as inland communities deal with the red flag warning.
With multiple advisories in place, the weekend weather picture is unusually broad. Fire risk, wind damage and coastal hazards are all part of the same system affecting Southern California.
