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.

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

A new atmospheric river will bring a new rainstorm to the Los Angeles area in the middle of the week, forecasters say.

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.
