A powerful atmospheric river inundated California late Sunday evening and Monday morning, bringing howling gusts and torrential rain that flooded roads, felled trees and snapped power lines. The storm lingered over Southern California on Monday, with some areas receiving record-breaking rainfall.

Flash flood warnings in the Los Angeles metro area were lifted on Monday morning by the National Weather Service, which no longer expects significant flooding to pose an immediate threat. But forecasters have warned that nonstop rain could continue piling on through Tuesday, increasing the potential for more flooding and landslides.

Mudslides covered the canyon roads in the Hollywood Hills after parts of the nearby Santa Monica Mountains received more than seven inches of rain over two days. Several homes in Studio City were damaged by debris flow brought by the rushing water into the neighborhood, which is in the San Fernando Valley, and some residents there were evacuated from their homes.

Rainfall totals in downtown Los Angeles surpassed six inches on Sunday, breaking a century-old daily rainfall record for Feb. 4, according to the National Weather Service. Eight to 14 inches of rain could fall on Monday in parts of Southern California, potentially dumping in a single day the amount of rain that Los Angeles usually averages in an entire year.

The latest storm is the second atmospheric river to drench California in a few days. Intense rain and strong winds hit the Bay Area and Central Coast beginning late last week, prompting road closures from flooding and debris flow and leaving hundreds of thousands of people without power.
