LOS ANGELES – The threat of renewed fire danger looms over Southern California as strong Santa Ana winds are forecast to intensify Monday night, further endangering communities already grappling with a series of devastating wildfires.

CALIFORNIA WILDFIRES: DEATH TOLL RISES AS LOS ANGELES AREA SEES 'PARTICULARLY DANGEROUS' FIRE WEATHER RETURN

The long-duration, multi-round fire weather event will last right through the middle of the week, with the worst of the winds occurring from Tuesday through Wednesday, the FOX Forecast Center said.

HOW TO WATCH FOX WEATHER

While the winds are not expected to be as strong as they were during last week's historic and deadly event, they will still be strong enough to impede the firefight and cause new and existing fires to spread rapidly.

The National Weather Service in Los Angeles said the fire weather "setup is about as bad as it gets."

The number of major wildfires decreased from five to three over the weekend, offering a temporary reprieve, but the situation remains critical. 

The Palisades and Eaton fires have burned nearly 38,000 acres, and containment levels for both remain extremely low. This, coupled with the imminent arrival of strong winds, poses a significant challenge for firefighters and increases the risk of further fire spread.

A "Particularly Dangerous Situation" Fire Weather Warning has been issued for parts of Los Angeles and Ventura counties.

"We've only had four of those, and the three previous ones that have happened in the past six months did result in fires,"  FOX Weather Meteorologist Britta Merwin said. "That's how we got the Mountain Fire, the Franklin Fire, and then, of course, the current situation that we're in."

While the winds will not stay consistently strong through Wednesday, a reoccurring cycle of northeasterly winds will flare up around 15-30 mph with gusts to 50 mph. A few gusts up to 70 mph will be possible in the San Gabriel, Santa Susana and western Santa Monica Mountains, the FOX Forecast Center said.

The most concerning area continues to be the Palisades Fire, where wind gusts will be in the 35-50 mph range. The good news is that the Eaton Fire should stay out of the strongest winds compared to areas just north and west of where the fire is burning.

Residents in affected areas are urged to remain vigilant and follow evacuation orders if issued.

"Thursday is the day that we are waiting for when onshore winds will return," Merwin said, providing firefighters with a more favorable environment to combat the blazes.
