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

The National Weather Service has provided a detailed timeline of when rain is expected to hit Los Angeles and Southern California this weekend.

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.

A cold storm system moves into Southern California this weekend, bringing with it the chance for rain and snow in some areas, also sparking concern for flash floods in recent burn scar areas.

With parts of Los Angeles County still smoldering from wildfires and new blazes flaring up, expected rainfall this weekend would seem like a welcome relief.

Local media reports that these winds could create "dangerous" fire weather conditions that could last all week.

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.

The particularly dangerous situation alert is relatively new to Southern California but has been issued before the recent wildfires that have caused devastation across LA County.

Rain in Southern California raises risk of toxic ash runoff in wildfire-scorched areas. Flood watches in effect, with potential mud and debris flows threatening affected regions.

Officials closed part of Pacific Coast Highway in the Palisades fire area on Sunday, Caltrans said, as rain poured down across the Los Angeles area and burn scars in Southern California were under a flood watch that will last until 4 p.m. Monday, according to the National Weather Service.

A number of considerable mudflows forced the closure of multiple roads in the Palisades Fire burn scar on Sunday.
