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

Malibu's Pacific Coast Highway, which just reopened after last month's devastating Palisades Fire, is closing again Tuesday due to concerns about potential mudslides, landslides and debris flows from a prolonged atmospheric river event.

The second peak of an ongoing atmospheric river storm arrived in Northern California Monday afternoon, prompting flood watches and a winter storm warning up in the Sierra.

Weeks after wildfires that killed at least 29 people and destroyed entire neighborhoods, Southern California is facing another extreme-weather threat: Too much rain.

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