The giant fires that are scouring Los Angeles have officially become the most destructive in the city’s history, killing at least six people and destroying at least 5,000 buildings. But as the winds driving the inferno have slackened, experts are cautiously optimistic that the blazes can soon be beaten back.
With reinforcements from other states, California firefighters have shifted from defense to offense. Rather than just saving individual buildings, they are now trying to stop the overall advance of the flames.
“Tuesday and Wednesday our priority was saving lives and protecting as much property as possible,” says LA Fire Department spokesperson Margaret Stewart. “Now that we’re able to operate at our full capacity, we’re able to have a more powerful assault.”
In a two-pronged attack, aircraft have ramped up dousing the fires from the air while firefighters and bulldozers starve them of fuel on the ground. At times earlier in the week, planes had to be grounded because of the severity of the wind.
“I would say [the tide] is turning,” says Ken Pimlott, former director of the California Department of Forestry and Fire Protection, or Cal Fire. “Today and tomorrow are really the key windows to get through, the red flag fire weather conditions. Then I think we’ll start to see much more progress.”
Massive fires began clawing through the Los Angeles metropolitan area on Tuesday thanks to a combination of long-standing drought and a bout of strong Santa Ana winds, seasonal air that blows from the high desert of Nevada and Utah into Southern California.
The Palisades Fire east of Malibu, which has burned almost 20,000 acres, was 0 percent contained on Thursday. Celebrities like Billy Crystal and Paris Hilton were among the many people who had lost their homes. The Eaton Fire in Pasadena, roughly 25 miles to the east, was also uncontained, but the fire department has been able to slow its growth. The Sunset Fire that started in the Hollywood Hills on Wednesday was quickly hemmed in, and two others are partially contained.
“The only fire that has that potential [to grow] is Palisades, and we have 1,100 people on that,” Stewart says.
The key factor has been the winds of up to 99 miles per hour. They’ve been raking down from the northeast to the southwest, fanning the flames and throwing burning embers half a mile in front of the main fire. Canyons running largely the same direction have funneled and intensified that movement of air, creating what Pimlott called a “blowtorch” that spread the Palisades Fire. The flames have been essentially unstoppable.
“These pressurized winds literally explode out of these canyons,” says Janet Upton, former deputy director of Cal Fire. “All you can do is work to get anything with a heartbeat out of the way.”
But the winds began easing up on Wednesday and Thursday. They were anticipated to reach 15 to 20 miles per hour Thursday afternoon, before ticking up to 30 to 40 miles per hour on Friday, according to the National Weather Service. Firefighters that were helpless against virtually unstoppable wind-driven blazes have been able to return to their normal tactics.
“With those winds being very calm this morning, I believe we can actually make some progress, turn a corner, and start to build some containment on these fires,” Brent Pascua, a Cal Fire battalion chief, told The Today Show on Thursday.
So far the disaster response has been marred by disinformation and controversy. After some fire hydrants ran dry, president-elect Donald Trump baselessly accused California governor Gavin Newsom of mismanaging the state’s water supplies to save an endangered fish.
City employees have now been able to reach three water tanks on hills near the Palisades Fire to turn up the pressure. That allows the tanks to be refilled more quickly so they can keep supplying the hydrants, Stewart says. Each tank can hold 1 million gallons. “We have full flowing hydrants,” she says.
More firefighters have begun to arrive from Utah, Oregon, Arizona, Washington, and New Mexico. Several dozen task forces are on their way, according to Stewart, each with five fire engines plus a command vehicle.
Aircraft began flying again on Wednesday. Twelve helicopters are filling humongous water buckets hanging from cables and sucking seawater up through snorkels. Six planes are also working the fires, including a pair of “super scoop” aircraft that have been skimming across the surface of the Pacific to pick up water. The helicopters and scoop planes dump water on spot fires, letting firefighters close in and extinguish them.
Meanwhile, other airplanes are dropping fire retardant out ahead of the inferno, coating potential fuel with a layer of nonflammable chemicals and slowing its advance. A C-130 cargo plane that Cal Fire acquired from the Coast Guard and retrofitted this summer can dump 4,000 gallons of retardant. That buys time for firefighters to dig and bulldoze firebreaks of bare soil.
With the ocean constraining the Palisades Fire to the south, responders will try to prevent it from breaking out to the east or west. “The real spread is going to be on the flank,” Pimlott says.
A red flag warning for increased fire risk will remain through Friday, with humidity at only 8–12 percent. California has been suffering an abnormally dry winter, with 40 percent of the state under drought conditions.
“Fuels remain critically dry,” James Magana of Cal Fire said at a Thursday morning briefing. “You can expect to see critical rates of spread, especially on those ridgetops or those drainages that are in alignment with the wind.”
On Saturday, the winds are expected to reverse direction. If firefighters aren’t ready, the heel of the fire could become the front and run off to the north.
Even once they’re able to contain the conflagration within a circle of firebreaks and natural barriers, that won’t be the end of the task. Firefighters will have to stamp out smaller fires within that footprint.
“That’s a critical stage, to mop up these hot spots or anything that could rekindle if the winds were to increase again,” Upton says.
Moving forward, the city will need to clean up debris, restore utilities, and analyze damage to the environment before allowing people to move back. With canyons depleted of the trees and vegetation that hold the soil, mudslides could become a threat once the rains return.
Los Angeles will face the prospect of rebuilding destroyed communities. That’s an opportunity to make them less vulnerable to the next fire, says Max Moritz, a wildfire specialist with the University of California Cooperative Extension.
Although houses are in many cases required to be built with fire-resistant materials, California law doesn’t say anything about how they should be laid out. Techniques like clustering homes rather than spreading them out among the trees can make them easier to defend from fire, and easier to evacuate, he says.
“That is part of the hope here, that we can do some of this better, smarter, and safer,” Moritz says.
