Incoming heavy rain from an atmospheric river-fueled storm that slammed into the West Coast early Wednesday is threatening mudslides and debris flows in Southern California and has already prompted evacuations in the Los Angeles area.

California braced for the arrival of a massive storm on Wednesday, evacuating residents in areas at risk of mudslides and debris flows.

Evacuation warnings were in place for several Los Angeles burn scar areas that were ravaged by wildfires two months ago.

A powerful March storm has been lashing the West Coast with heavy rainfall, gusty winds and snowfall in the mountains –– shifting southward and posing a particular threat to communities scorched by the deadly Los Angeles wildfires from the start of the year.

A strong storm system is expected to “blast through” Los Angeles and Orange County tonight, bringing a heavy dose of rain over a short period of time and prompting evacuation orders, flood warnings and road closures.
