Another “potentially dangerous situation red flag warning” hit Southern California on Monday afternoon, as fire crews braced for the potential of new wildfires during troubling winds while still working to contain two of the most devastating fires in Los Angeles County history.

The third such official warning this month was “unprecedented for this area,” James White, a meteorologist with the National Weather Service, said during a briefing on the Eaton fire. The warning was set to last until 10 a.m. today.

Afterward, the winds were expected to die down, becoming breezy into Thursday evening, although dry conditions would persist. A chance of light precipitation was forecast for the fire areas Saturday and Sunday.

White said this windstorm would fall between the first two — weaker than the one on Jan. 7, when the fires erupted, but stronger than a second round last week that fell below forecasters’ expectations.

“We’re expecting today two main concerns — one is that it’s going to get dry very, very quickly,” White said. “The second thing we’re expecting is strong northeast winds.”

Peak wind gusts could reach upward of 70 mph in coastal and valley areas and 100 mph in the mountains, according to the weather service.

Because of “extremely high winds and fire danger,” the Federal Emergency Management Agency said it closed its Disaster Recovery Center in Pasadena at 5 p.m. Monday and said that, depending on weather conditions, it may remain closed today.

Regular hours at the center, at Pasadena City College, are 9 a.m. to 8 p.m. Monday through Sunday.

For updated information on the center’s status, see the FEMA Region 9 X account.

A second Disaster Recovery Center in the region is at UCLA Research Park, 10850 W Pico Blvd., Los Angeles. It’s also open daily from 9 a.m. to 8 p.m.

Former Vice President Kamala Harris and her husband, Doug Emhoff, flew to Los Angeles after attending President Donald Trump’s inauguration and met with firefighters, volunteers and victims of the Eaton fire in Altadena.

“We just came out to thank (firefighters), to thank the community and just remind folks that we’re all in this together,” Harris said.

She said their home in Pacific Palisades was still standing.

Fire officials battling both the Eaton and Palisades fires said they were prepared for a new fire or the expansion of an existing one. Firefighters and equipment were positioned in high-risk areas within the county, and additional resources were poised for deployment at a mobilization center in Beaumont.

But firefighting planes and helicopters could be grounded if the winds kick up beyond 30 to 40 mph.

“That limits what the aircraft can do,” said Dennis Burns, a fire behavior analyst with California Interagency Incident Management Team 2 on the Eaton fire.

Robert Garcia, fire chief for the U.S. Forest Service, said Monday morning there were no plans to ground aircraft. Pilots, however, would monitor the wind at takeoffs.

The windstorm was set to arrive as fire crews continued making progress with containment on both the Eaton and Palisades fires.

Aircraft continued to assist firefighters battling the Eaton fire by extinguishing hot spots in steep terrain near Winters Creek, Mount Lowe and Mount Wilson, Angeles National Forest officials said. The fire was 87% contained as of Monday afternoon, 6% higher than the previous evening.

Officials also slightly downgraded the destroyed acreage from the fire, which now stands at 14,021, nearly 100 acres less than what had been reported for most of last week, due to “better flights and sights” on the fire, officials said.

Near the coast, the Palisades fire was 61% contained as of Monday afternoon, up from 56% the evening before, as firefighters continue to make steady progress, Cal Fire officials said.

“Stay alert as the danger has not yet passed,” Los Angeles Fire Department Chief Kristin Crowley said.

The Eaton fire has destroyed at least 9,416 structures and damaged 1,064, according to Cal Fire. That count includes homes and commercial structures.

The Palisades blaze has damaged or destroyed at least 6,051 structures, officials said Monday afternoon, with 4,964 of them homes. More than 24,500 people remained evacuated.

While some residents have been allowed to return home, others remained under evacuation orders as officials continue to mitigate the dangers and search for missing persons. At least 27 deaths have been attributed to both fires combined so far, according to the Los Angeles County medical examiner’s department.

The fires are expected to be the costliest natural disaster in U.S. history by the time all of the damage is assessed.
