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.

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.

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 was falling on the region Sunday and is expected to get heavier overnight, according to a Sunday afternoon forecast from the National Weather Service. Los Angeles and Ventura counties may get as much as 1.25 inches (3.2 centimeters) through Monday, with as much as 2 inches in the mountains.

A flash-flood watch went into effect at 10 a.m. Sunday that includes fire-scarred areas of Souther California, with forecasters boosting their predictions for rainfall that carry the risk of significant flash flooding.
