Firefighters scrambled on Sunday to make further progress against wildfires that have killed 16 people in the Los Angeles area as forecasters again warned of dangerous weather with the return of strong winds this week.
At least 16 people were missing, and authorities said that number was expected to rise.
The National Weather Service issued red flag warnings for severe fire conditions through to Wednesday, with sustained winds of 50mph (80kph) and gusts in the mountains reaching 70mph (113kph).
The most dangerous day will be Tuesday, said weather service meteorologist Rich Thompson.
“You’re going to have really strong gusty Santa Ana winds, a very dry atmosphere and still very dry brush, so we still have some very critical fire weather conditions out there,” Mr Thompson said at a community meeting on Saturday night.
Fierce Santa Ana winds have been largely blamed for turning the wildfires sparked last week into infernos that levelled entire neighbourhoods around the city where there has been no significant rainfall in more than eight months.
Twelve people were missing within the Eaton Fire zone and four from the Palisades Fire, Los Angeles County Sheriff Robert Luna said on Sunday morning.
Meanwhile, the death toll rose to 16 over the weekend. Five of the deaths were attributed to the Palisades Fire and 11 resulted from the Eaton Fire, the Los Angeles County coroner’s office said in a statement on Saturday evening.
The previous number of confirmed fatalities before Saturday was 11, but officials said they expected that figure to increase as teams with dogs conduct systematic grid searches in levelled neighbourhoods.
Authorities have established a centre where people can report the missing.

Officials were building an online database to allow evacuated residents to see if their homes were damaged or destroyed.
In the meantime, LA city fire chief Kristin Crowley urged people to stay away from scorched neighbourhoods, saying: “There are still active fires that are burning within the Palisades area, making it extremely, extremely dangerous for the public.
“There’s no power, there’s no water, there’s broken gas lines, and we have unstable structures. The first responders are working as quickly as possible to ensure that it is safe for you to return into your communities.”

Officials warned the ash can contain lead, arsenic, asbestos and other harmful materials.
About 150,000 people in Los Angeles County remained under evacuation orders, with more than 700 residents taking refuge in nine shelters, Mr Luna said.
By Sunday morning, Cal Fire reported the Palisades, Eaton, Kenneth and Hurst fires had consumed more than 62 square miles (160 square kilometres), an area larger than San Francisco.
The Palisades Fire was 11% contained and containment on the Eaton Fire reached 27%. Those two blazes accounted for 59 square miles (nearly 153 square kilometres).
Crews from California and nine other states are part of the ongoing response that includes 1,354 fire engines, 84 aircraft and more than 14,000 personnel, including newly arrived firefighters from Mexico, he said.
