The previous number of confirmed fatalities was 11, but officials said they expected that figure to rise as cadaver dogs search leveled neighborhoods and crews assess the devastation. Authorities have established a center where people can report the missing.

Firefighters raced to cut off spreading wildfires before potentially strong winds return that could push the flames toward the world famous J. Paul Getty Museum and the University of California, Los Angeles, while new evacuation warnings left more homeowners on edge.

A fierce battle against the flames was underway in Mandeville Canyon, home to Arnold Schwarzenegger and other celebrities not far from the Pacific coast, where swooping helicopters dumped water as the blaze charged downhill. Firefighters on the ground used hoses in an attempt to beat back leaping flames as thick smoke blanketed the chaparral-covered hillside.

At a briefing, CalFire Operations Chief Christian Litz said a main focus Saturday would be the Palisades Fire burning in the canyon area, not far from the UCLA campus.

“We need to be aggressive out there,” Litz said.

County Supervisor Lindsey Horvath said the LA area “had another night of unimaginable terror and heartbreak, and even more Angelenos evacuated due to the northeast expansion of the Palisades Fire.”

Light breezes were fanning the flames, but the National Weather Service warned that strong Santa Ana winds — the nemesis of firefighters — could soon return. Those winds have been largely blamed for turning the wildfires into infernos that leveled entire neighborhoods around to city where there has been no significant rainfall in more than eight months.

The fire also was threatening to jump over Interstate 405 and into densely populated areas in the Hollywood Hills and San Fernando Valley.

The hunt for bodies continues

The grim work of sifting through the devastation continued Saturday, with teams conducting systematic grid searches with cadaver dogs, said Los Angeles County Sheriff Robert Luna. He said a family assistance center was being established in Pasadena, and he urged residents to abide by curfews.

“We have people driving up and around trying to get in just to look. Stay away,” he said.

The fires have consumed about 56 square miles (145 square kilometers), an area larger than San Francisco. Tens of thousands of people remained under evacuation orders and new evacuations were ordered Friday evening after a flare up on the eastern side of the Palisades Fire.

Since the fires first began Tuesday just north of downtown LA, they have burned more than 12,000 structures, a term that includes homes, apartment buildings, businesses, outbuildings and vehicles.

No cause has been determined for the largest fires, and early estimates indicate the wildfires could be the nation’s costliest ever. A preliminary estimate by AccuWeather put the damage and economic losses so far between $135 billion and $150 billion.

Rays of kindness amid the devastation

So many volunteers showed up to help at donation centers Saturday that some were being turned away. That was the case at a YMCA in the Koreatown neighborhood. By late morning, cars with would-be helpers were also being turned back from the Santa Anita Park horse racing track, where donations of necessities were being accepted.

At the race track Friday, people who lost their homes could be seen sifting through stacks of donated shirts, blankets and other household goods. Altadena resident Jose Luis Godinez said three homes occupied by more than a dozen of his family members were destroyed.

“Everything is gone,” he said, speaking in Spanish. “All my family lived in those three houses and now we have nothing.”

Officials warn against returning to burned homes

Some residents have been venturing back to see what can be salvaged after wildfires destroyed their homes, sifting through rubble for keepsakes. But officials on Saturday urged them to stay away, warning that the ash can contain lead, arsenic, asbestos and other harmful materials.

“If you’re kicking that stuff up, you’re breathing it in,” said Chris Thomas, a spokesman for the unified incident command at the Palisades Fire. “All of that stuff is toxic.”

Residents will be allowed to return, with protective gear, after damage teams have evaluated their properties, Thomas said.

City leadership accused of skimping on firefighting funds

Allegations of leadership failures and political blame have begun and so have investigations. Gov. Gavin Newsom on Friday ordered state officials to determine why a 117 million-gallon (440 million-liter) reservoir was out of service and some hydrants had run dry. Meanwhile, Los Angeles Fire Chief Kristin Crowley said city leadership failed her department by not providing enough money for firefighting. She also criticized the lack of water.

“When a firefighter comes up to a hydrant, we expect there’s going to be water,” she said.

Progress made on fighting the Eaton fire

Firefighters for the first time made progress Friday afternoon on the Eaton Fire north of Pasadena, which has burned more than 7,000 structures. Officials said most evacuation orders for the area had been lifted.

LA Mayor Karen Bass, who faces a critical test of her leadership as her city endures its greatest crisis in decades, said several smaller fires also were stopped.

The level of devastation is jarring even in a state that regularly confronts massive wildfires.
