An atmospheric river brings the threat of rain and flooding to California

Rain from a torrential river lashed parts of California early Monday as a new storm began testing the state’s preparedness weeks after deadly flooding caused power outages and devastating mudslides.

Flood watches were in effect for millions of people, mostly in California, until Wednesday as the possibility of thunderstorms, strong winds and rain continued to threaten the central and southern coasts.

“So the ground is pretty sensitive,” said Brian Hurley, a senior meteorologist with the National Weather Service, referring to the significant rainfall the state has experienced in recent weeks. “That is why you now see many of the flood watch.”

The State Emergency Service announced this on Sunday she had emergency teams deployedincluding helicopters and rapid water rescue teams, in 14 counties ahead of the expected impact of the stormy river.

This was announced by the National Weather Service in Los Angeles total expected rainfall two to five inches for much of Southern California, with a higher range of four to eight inches expected in the mountains and foothills.

Urban flooding and mudslides were possible in Santa Barbara, Ventura and Los Angeles counties during periods of heavy rainfall, the National Weather Service said, adding that there were a high chance of thunderstorms.

Santa Barbara County officials over the weekend issued an evacuation warning to Wednesday for certain communities.

Communities in Los Angeles County, where relatively less rain was expected, and beyond facing the risk of landslides and debris on roads as the area “took the brunt of the latest storm,” the weather service said.

Karen Bass, Mayor of Los Angeles, begged residents over the weekend prepare.

Homeowners and workers in the city’s hilly neighborhoods spent Sunday preparing sandbags and placing plastic tarps over muddy hillsides still scarred from the latest storm.

Some residents, including Staci Broussard, 58, made sure to fortify their properties shortly after the storm ended. Ms. Broussard’s home in Baldwin Hills Estates, a neighborhood overlooking South Los Angeles, was damaged by a previous storm surge that swept through the city.

The slope behind Mrs. Broussard’s house collapsed, knocking down part of the iron fence in the yard, bringing mud and vegetation down the hill from her neighbor’s house on the hill above.

Ms. Broussard and her neighbor placed tarps over the slopes to prevent more mud from sliding down.

“As you can see, we have tarps everywhere because unfortunately it happens everywhere in this area,” she said on Sunday.

Los Angeles Weather Service warned boaters of dangerous conditions at sea, suggesting they stay in port. The storm also threatened to erode the shoreline and damage structures there, officials said.

Farther north, forecasters said thunderstorms, gusty winds and lightning were possible in the Bay Area Monday afternoon. The San Francisco Peninsula, which includes the city of San Francisco, is expected to receive up to two and a half inches of rain. The Santa Cruz Mountains and the Big Sur coast could get three to five and three to six inches, respectively.
