A rare alert called a "Particularly Dangerous Situation" is in effect Wednesday for parts of fire-ravaged southern California. The National Weather Service initially issued the warning for Tuesday but extended it after Tuesday’s conditions were less hazardous than expected.

A slow-moving low-pressure system will linger over the Southwest, bringing steady rain through at least Monday.

The highest intensity rain was expected between 4 p.m. on Sunday and 4 p.m. on Monday, according to the service. Los Angeles and Ventura Counties were expected to get up to an inch of total rainfall, and up to three inches was forecast in the mountains around Los Angeles.

Residents and first responders were on high alert for possible land movement in recent burn scar areas as a winter storm moves in.

There is a 10% to 20% chance of flash flooding and landslides in some recently burned areas of Los Angeles County, forecasters say, including the Palisades and Eaton fire areas.

Firefighters made progress on the more than 10,000-acre Hughes Fire Friday, which sent thousands fleeing after sparking near the Los Angeles County community of Castaic a day earlier.

A fire broke out Wednesday night along the 405 Freeway in the Sepulveda Pass near the Getty Center, burning about 20 acres and spurring an evacuation warning.

Three active fires in Los Angeles neared full containment Sunday, as the region receives much-needed rain that has produced flood and mudslide warnings lasting through Monday. Saturday, 4:00 p.m. PST Cal Fire data marked the Palisades Fire at 87% containment, the Eaton Fire at 95% containment and the Hughes Fire at 92% containment.

Rain fell across parts of Southern California, providing relief to firefighters battling wildfires but raising concerns about toxic ash runoff and mudslides. Despite progress in containing major fires,
