Windy and dry conditions returned to Southern California on Monday, raising the risk of new wildfires sparking as firefighters continue to battle two major blazes in the Los Angeles area that started in similar weather nearly two weeks ago.

Gusts could peak at 113 kph along the coast and 160 kph in the mountains and foothills during extreme fire weather that is expected to last through Tuesday.

The National Weather Service issued a warning of a “particularly dangerous situation” for parts of Los Angeles and Ventura counties from Monday afternoon until Tuesday morning due to low humidity and damaging Santa Ana winds.

Authorities urged people not to mow their lawns to prevent sparking a fire, nor start any fires that could get out of control.

They also asked residents to review their evacuation plans and ready emergency kits and be on the lookout for any new blazes and report them quickly.

David Acuna, a spokesman with the California Department of Forestry and Fire Protection, said the biggest concerns are the Palisades and Eaton Fires breaking their containment lines and a new blaze starting.

“Don’t do things to start another fire so we can focus on the mitigation of the current fires,” Acuna said.

The low humidity, bone-dry vegetation and strong Santa Ana winds come as firefighters continue to battle two major blazes in the Los Angeles area, the Palisades and Eaton fires, which have destroyed more than 14,000 structures since they broke out during fierce winds on January 7.

The Palisades fire was 59 per cent contained on Monday and the Eaton fire 87 per cent contained, according to fire officials.

Donald Trump, who was sworn in as US president on Monday, has said he will be visiting the fire-ravaged areas at the end of the week.

That trip could include an awkward encounter with California Governor Gavin Newsom, who has been the target of Trump's barbs over his handling of the disaster.

He has falsely claimed that Newsom had blocked the diversion of "excess rain and snow melt from the North."

In reality, Los Angeles' water supplies are mainly fed via aqueducts and canals originating from entirely separate river basins further east. (Agencies)
