Areas charred by last month's wildfires in Southern California now face a new threat from a powerful, but fast-moving Pacific storm. Here's what you need to know about this threat.

An atmospheric river is expected to bring torrential rain to California this week, threatening parts of the state with flash floods and mudslides.

A major atmospheric river storm is barreling toward California, raising the specter of damaging landslides and flooding across much of the Southland.

An atmospheric river brought additional rain, strong winds, and flooding to the Bay Area Tuesday, with an increasing chance of thunderstorms later in the afternoon.

Days after an atmospheric river brought record-setting rainfall to California, the state is in the crosshairs of another rainy storm system.

There is now a 30% chance of intense rain between Feb. 12 and 15 in Los Angeles, Ventura, Santa Barbara and San Luis Obispo counties, the National Weather Service said.

According to The Weather Channel, the storm raises major concerns for flash flooding and debris flows, especially in areas recently scorched by wildfires, including the Eaton and Palisades fire zones in Southern California.

The first wave of the strongest storm of the winter began hitting Southern California on Wednesday, but the most damaging rains are expected Thursday.
