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.

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

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.
