A powerful atmospheric river has arrived Sunday, bringing very heavy rain and potentially life-threatening flash flooding as well as mountain snow to much of the Southland through Tuesday, prompting Governor Gavin Newsom to declare a state of emergency in eight counties in the state, including Los Angeles and Orange counties. 

The National Weather Service says rain will continue through Tuesday with a high threat of excessive rainfall and flooding. As of 11 a.m. PT, the NWS said the heaviest rain had shifted to Los Angeles County and will last longest over the region as the system arrives. High rainfall totals are anticipated, including 4″-8″ for LA County, 8″-14″ for the mountains and foothills, with a 20-percent chance of thunderstorms. But widespread flooding will be the biggest threat.

“Angelenos, my pledge to you is to keep you informed and to make sure the city is operating in an all-hands-on-deck manner to keep Angelenos safe. Storms can change quickly, but let me be clear: this storm is a serious weather event. This has the potential to be a historic storm, severe winds, thunderstorms, and even brief tornadoes,” said Mayor Karen Bass during an afternoon news briefing. 

According to the NWS, the strongest rain and wind will arrive by afternoon and into the evening through Monday morning. Forecasters say the coastal side of the mountains will also be affected. Heavy rain will linger, which is why the NWS has asked the public to work remotely, if possible, Monday.

Flood Watch remains in effect

A flood watch remains in effect for all areas. According to forecasters, flooding is possible along freeways, as well as in neighborhoods, impacting even parked cars due to the sheer amount of anticipated rain. Commuters are urged to avoid freeways Monday morning. 

Strong, damaging winds are likely, prompting the NWS to issue a rare, winter storm warning for Ventura County and northward, as well as for the mountains of San Bernardino and Riverside counties, including Big Bear City, Big Bear Lake, Running Springs, and Wrightwood. The winter storm warning means excessive rainfall could produce flash flooding. 

Los Angeles County is not under the storm warning, but is under a gale warning, which means sustained surface winds, or frequent gusts, in the range of 34 knots (39 mph) to 47 knots (54 mph), is either predicted or occurring. Winds will be lighter Monday and into Tuesday. Stronger winds could return by Wednesday.

The storm also impacted power in twelve counties across the state, resulting in 217,445 residents being impacted, as of 5 p.m. ET. The impacted counties include Mendocino, Sonoma, Lake, Yolo, Santa Clara, Monterey, Santa Cruz, Alameda, Santa Barbara, Napa, Solano, and San Luis Obispo.
