Gusting Santa Ana winds and dangerously dry conditions have returned to the region, prompting forecasters to issue a red flag warning of critical fire danger that will continue Friday.

The warning went into effect at 9 p.m. Wednesday and will be in place until 6 p.m. Friday for San Diego County mountains and inland valleys.

According to the National Weather Service, the forecast calls for east winds of 20 to 30 mph, with gusts reaching 55 mph, and some isolated gusts as high as 65 mph in "wind-favored" locations.

Humidity levels will fall to between 5% and 10%.

"Any fires that develop will likely spread rapidly," according to the NWS. "Outdoor burning is not recommended."

The winds are expected to diminish by the weekend, along with a gradual recovery in humidity.

While the mountain and valley areas remain at risk for a public safety power shutoff, 4,452 county residents woke up Friday morning to no power, according to San Diego Gas & Electric. Around 7:30 a.m., outages were planned for Alpine, Boulevard, Campo Reservation, Descanso, Fallbrook, Jamul, Potrero and Warner Springs. Unplanned outages were also reported in the county.

More than 40 communities could be impacted by outages. The utility company reported that 48,783 customers could potentially be affected.

A small spot fire was reported Wednesday evening off Interstate 8 in Alpine. At 1:20 a.m. Friday, a brush fire burned off the northbound Escondido (15) Freeway at the interchange with the Martin Luther King Jr. (94) Freeway. A total of 32 firefighters were assigned, including one helicopter, officials said. No evacuations were ordered. No injuries were reported.

Capt. Frank Lococo of Cal Fire said the agency is prepared to respond, with five additional engines on loan from Northern California.

San Diego County government officials on Wednesday asked residents to stay alert for wildfires, and refrain from using power tools outdoors, including lawn mowers, as they can potentially spark on rocks and ignite grass or brush fires. Instead, residents should use hand tools to remove dead or dying plants near their homes.

The county also reminded residents to maintain defensible fire space around their homes and remove dead leaves, debris and other flammable items, such as wood piles, that are stacked against structures.

During a high-fire season, people should also:

— be careful with smoking materials to avoid accidentally starting a fire;

— never pull their vehicle over in grass as it can ignite a blaze, and make sure their vehicle is well maintained; and

— if their vehicle has a trailer, make sure its chains don't drag on the ground while driving.
