After making some progress battling wildfires that destroyed thousands of homes and killed at least 24 people in the Los Angeles area, firefighters are preparing for a return of dangerous winds that could again stoke the flames Monday.

Here’s the latest:

What ignited the deadly California wildfires?

Investigators are considering an array of possible ignition sources for the huge fires that have killed at least 24 people and destroyed thousands of homes and businesses in the Los Angeles area.

In the Pacific Palisades, officials have placed the origin of the wind-whipped blaze behind a home on Piedra Morada Drive, which sits above a densely wooded arroyo.

According to the National Fire Protection Association, lightning is the most common cause of fires in the U.S., but investigators were able to rule that out quickly. There were no reports of lightning in the Palisades area or the terrain around the Eaton Fire, which started in east Los Angeles County and has destroyed hundreds of homes.

The next two most common causes: fires intentionally set, and those sparked by utility lines.

John Lentini, owner of Scientific Fire Analysis in Florida, who has investigated large fires in California including the Oakland Hills Fire in 1991, said the size and scope of the blaze don’t change the approach to finding out what caused it.

Firefighters continue battling the flames

Crews from California and nine other states are part of the ongoing response that includes nearly 1,400 fire engines, 84 aircraft and more than 14,000 personnel, including newly arrived firefighters from Mexico.

After a fierce battle Saturday, firefighters managed to fight back flames in Mandeville Canyon, home to Arnold Schwarzenegger and other celebrities near Pacific Palisades not far from the coast, where swooping helicopters dumped water as the blaze charged downhill.

Meghan Markle delays Netflix series launch, composer’s works lost

Several projects and awards shows have been delayed, with the Producers Guild opting not to announce its nominations Sunday due to the ongoing effects of the fire. Meghan, the Duchess of Sussex, also announced she wouldn’t launch a Netflix lifestyles program until March.

The publisher of composer Arnold Schoenberg’s works says original manuscripts and scores were lost in the Los Angeles wildfires.

“We have lost our full inventory of sales and rental materials,” the company said in a statement. “We hope that in the near future we will be able to ‘rise from the ashes’ in a completely digital form. … There are some scores and performing materials for which we have digital scans.”

Meanwhile, The Screen Actors Guild has joined the Walt Disney Co., the Grammys and other entertainment entities pledging millions in relief to help those affected by the fires.

The relative calm Sunday allowed some people to return to previously evacuated areas. But even as containment increased in the worst of the fires, more bad news emerged from the ashes: The death toll surged late Sunday with an update from the Los Angeles County medical examiner. At least 16 people were missing, a number authorities said was also likely to rise.
