Everyone knows the story of Mrs. O’Leary’s cow, the one that allegedly knocked over a lantern in 1871 and burned down 2,100 acres of downtown Chicago. While the wildfires raging in Los Angeles County have already far exceeded that legendary bovine’s total attributed damage — at the time of this writing, on Thursday morning, five fires have burned more than 27,000 acres — the losses had centralized, at least initially, in the secluded neighborhoods and idyllic suburbs in the hills above the city.
On Wednesday, that started to change. Evacuation maps have since extended into the gridded streets of downtown Santa Monica and Pasadena, and a new fire has started north of Beverly Hills, moving quickly toward an internationally recognizable street: Hollywood Boulevard. The two biggest fires, Palisades and Eaton, remain 0% contained, and high winds have stymied firefighting efforts, all leading to an exceedingly grim question: Exactly how much of Los Angeles could burn. Could all of it?
“I hate to be doom and gloom, but if those winds kept up … it’s not unfathomable to think that the fires would continue to push into L.A. — into the city,” Riva Duncan, a former wildland firefighter and fire management specialist who now serves as the executive secretary of Grassroots Wildland Firefighters, an advocacy group, told me.
When a fire is burning in the chaparral of the hills, it’s one thing. But once a big fire catches in a neighborhood, it’s a different story. Houses, with their wood frames, gas lines, and cheap modern furniture, might as well be Duraflame. Embers from one burning house then leap to the next and alight in a clogged gutter or on shrubs planted too close to vinyl siding. “That’s what happened with the Great Chicago Fire. When the winds push fires like that, it’s pushing the embers from one house to the others,” Duncan said. “It’s a really horrible situation, but it’s not unfathomable to think about that [happening in L.A.] — but people need to be thinking about that, and I know the firefighters are thinking about that.”
Once flames engulf a block, it will “overpower” the capabilities of firefighters, Arnaud Trouvé, the chair of the Department of Fire Protection Engineering at the University of Maryland, told me in an email. If firefighters can’t gain a foothold, the fire will continue to spread “until a change in driving conditions,” such as the winds weakening to the point that a fire isn’t igniting new fuel or its fuel source running out entirely, when it reaches something like an expansive parking lot or the ocean.
This waiting game sometimes leads to the impression that firefighters are standing around, not doing anything. But “what I know they’re doing is they’re looking ahead to places where maybe there’s a park, or some kind of green space, or a shopping center with big parking lots — they’re looking for those places where they could make a stand,” Duncan told me. If an entire city block is already on fire, “they’re not going to waste precious water there.”
Urban firefighting is a different beast than wildland firefighting, but Duncan noted that Forest Service, CALFIRE, and L.A. County firefighters are used to complex mixed environments. “This is their backyard, and they know how to fight fire there.”
“I can guarantee you, many of them haven’t slept 48 hours,” she went on. “They’re grabbing food where they can; they’re taking 15-minute naps. They’re in this really horrible smoke — there are toxins that come off burning vehicles and burning homes, and wildland firefighters don’t wear breathing apparatus to protect the airways. I know they all have horrible headaches right now and are puking. I remember those days.”
If there’s a sliver of good news, it’s that the biggest fire, Palisades, can’t burn any further to the west, the direction the wind is blowing — there lies the ocean — meaning its spread south into Santa Monica toward Venice and Culver City or Beverly Hills is slower than it would be if the winds shifted. The westward-moving Santa Ana winds, however, could conceivably fan the Eaton fire deeper into eastern Los Angeles if conditions don’t let up soon. “In many open fires, the most important factor is the wind,” Trouvé explained, “and the fire will continue spreading until the wind speed becomes moderate-to-low.”
Though the wind died down a bit on Wednesday night, conditions are expected to deteriorate again Thursday evening, and the red flag warning won’t expire until Friday. And “there are additional winds coming next week,” Kristen Allison, a fire management specialist with the Southern California Geographic Area Coordination Center, told me Wednesday. “It’s going to be a long duration — and we’re not seeing any rain anytime soon.”
Editor’s note: Firefighting crews made “big gains” overnight against the Sunset fire, which threatened famous landmarks like the TLC Chinese Theater and the Dolby Theatre, which will host the Academy Awards in March. Most of the mandatory evacuation notices remaining in Hollywood on Thursday morning were out of precaution, the Los Angeles Times reported. Meanwhile, the Palisades and Eaton fires have burned a combined 27,834 acres, destroyed 2,000 structures, killed at least five people, and remain unchecked as the winds pick up again.
