A powerful atmospheric river batters California with floods, mudslides, and outages as Gov. Newsom declares emergency in multiple counties.

A winter storm is hitting New York City and other parts of the Northeast, but an atmospheric river that dumped rain on California most of the week was easing.

A massive rainstorm is sweeping across Southern California on a busy travel day. Parts of Orange County were ordered to evacuate amid debris flow risk, while officials warn of rockslides.

Forecasters measured 4.52 inches of rain at the Santa Barbara Airport on Christmas, beating the previous record of 2.17 inches set in 1955.

A California storm on Christmas Eve caused flooding and mudslides, and prompted evacuations, power outages, and travel warnings as heavy rains hit the region.

Forecasters said heavy rain was expected to drench much of Southern California through the holidays, and officials warned the storm could be deadly.

Another powerful storm system that could cause more flooding and mudslides is rolling across Southern California.

Rain will pick up Wednesday morning, with the heaviest downpours forecast from Wednesday night into Thursday afternoon, according to the National Weather Service.
