Powerful winds forecast for late Tuesday night threatened to whip up massive fires that are still burning around Los Angeles, possibly worsening a tragedy that has killed at least 25 people.
Powerful winds forecast for late Tuesday night threatened to whip up massive fires that are still burning around Los Angeles, possibly worsening a tragedy that has killed at least 25 people.
A week after blazes erupted and spread uncontained, forecasters predicted "particularly dangerous" Santa Ana winds would spike.
"Stay aware of your surroundings. Be ready to evacuate. Avoid anything that can spark a fire," the National Weather Service said, warning of gusts up to 70 miles (110 kilometers) an hour between 3am (1100 GMT) and 3pm (2300 GMT) on Wednesday.
Part of Los Angeles County and much of neighboring Ventura County were in a "Particularly Dangerous Situation," according to the NWS, a designation that was in effect before last week's deadly blazes.
"All the plants and vegetation is really dry and ready to burn so... fires can grow pretty fast," meteorologist Ryan Kittell told AFP.
The Palisades and Eaton fires -- both of which are still burning in places -- could flare up, and new ignitions could quickly turn problematic, Kittell said.
Officials insisted they were poised for any renewed threats, particularly around the existing burn sites, after hydrants ran dry in the initial firefight.
"Please be assured that the Los Angeles County region is prepared," fire chief Anthony Marrone said.
"We have checked the water system in the Eaton fire area, and it is operational, meaning that we have water and we have pressure."
The renewed danger comes with 24,000 acres (9,700 hectares) of the upmarket Pacific Palisades in ruins and 14,000 acres (5,700 hectares) of the community of Altadena badly charred.
Gusting winds were also whipping up toxic ash, with health officials urging everyone to wear a mask.
"Ash is not just dirt," said Anish Mahajan of the LA County Public Health Department.
"It's hazardous fine dust that can irritate or harm your respiratory system and other parts of your body where it lands."
California Governor Gavin Newsom on Tuesday ordered debris removal teams to be on standby, as emergency managers look ahead to possible winter rainstorms that could provoke mudslides.
Around 88,000 people remain displaced.
For those whose homes survived, there is frustration about not being able to return.
For others, there is nothing left.
"We all left with the clothes on our back," Sonja Jackson told the Los Angeles Times as she waited in line for government help.
"We thought we’d be able to come back in the morning. We didn’t think the fires were gonna do what they did."
The scale of the disaster was still difficult for many to grasp, with Los Angeles Mayor Karen Bass saying it was only after flying over it that she had started to appreciate the immensity of the damage.
"It's one thing to see it on television, it's another thing to see it from air. The massive, massive destruction is unimaginable until you actually see it," she said.
AccuWeather increased its assessment of the total cost of the tragedy to between $250 billion and $275 billion, a figure that would make it one of the most costly in US history.
Federal authorities said Tuesday they have launched a probe into the causes of the fires, but warned it could take time.
"We know everyone wants answers, and the community deserves answers. ATF will give you those answers, but it will be once we complete a thorough investigation," said Jose Medina of the federal Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
Late night talk show host Jimmy Kimmel was back on the air Monday night after having to evacuate his studio last week when a blaze erupted in the Hollywood Hills, just a few hundred meters (yards) away.
"It's been a very scary, very stressful, very strange week here in LA, where we work, where we live, where our kids go to school," an emotional Kimmel told his audience.
"It's been terrible. Everyone who lives in this city knows someone... whose house has burned down. And the truth is we don't even know if it's over."
With so many in dire straits, the city was clutching for any sliver of good news, with some taking refuge in local sports teams who were back in action.
The Los Angeles Rams dominated the Minnesota Vikings in an NFL play-off game, to take them one step closer to the Super Bowl, cheered on by fans brandishing flags and signs thanking firefighters.
"We knew what we were playing for," Rams quarterback Matthew Stafford said.
"It's a tough time. We're just happy that we came out and played like this tonight to get (fans) something to be happy about."
