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

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.

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.

The Hughes Fire that started on Wednesday has burned through over 5,000 acres in Los Angeles and Ventura Counties on Wednesday.

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

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.

A particularly dangerous situation red flag warning is in place from noon Monday to 10 a.m. Tuesday local time for a large portion of Ventura and Los Angeles counties.

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.

After weekend rainfall caused mudslides in wildfire burn scar areas and snow created dangerous driving conditions, several roadways and schools were closed across the Southern California region.

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.
