Lingering thunderstorms bring flooding risk after atmospheric river drenches much of California

LOS ANGELES — A powerful atmospheric river had mostly moved through California after causing at least six deaths and dousing much of the state, but lingering thunderstorms brought the risk of mudslides in areas of Los Angeles County that were recently ravaged by wildfire.

Flood advisories remained in place through Sunday afternoon for LA, Ventura and Santa Barbara counties, where localized showers were still possible after heavy downpours on Friday and Saturday.

“Due to the abundant rainfall the past couple of days, it will not take as much rainfall to cause additional flooding/rockslide conditions,” the National Weather Service said in a Sunday update.

A slow-moving storm is soaking California, especially the L.A. Basin. Flooding, debris flows, rockslides and even a few thunderstorms are possible. Here's the latest: https://t.co/WiKLBITwYl

Authorities on Sunday were still searching for a 5-year-old girl who was swept into the ocean by 15-foot waves at a state beach in Monterey County on Friday. The girl’s father, 39-year-old Yuji Hu, of Calgary, Alberta, was killed while trying to save his daughter, sheriff’s officials said.

In Sutter County north of Sacramento, a 71-year-old man died Friday after his vehicle was swept off a flooded bridge, according to the California Highway Patrol.

Off the coast of San Diego, a wooden boat believed to have been ferrying migrants toward the U.S. from Mexico capsized in stormy seas, leaving at least four people dead and four hospitalized, the Coast Guard said Saturday.

Heavy rainfall from Saturday led to scenes like this: dried-up desert beds that easily flooded.

The long plume of tropical moisture that formed over the Pacific Ocean began drenching the San Francisco Bay Area on Wednesday night and then unleashed widespread rain over Southern California on Friday and Saturday. More than 4 inches of rain fell over coastal Santa Barbara County as the storm approached Los Angeles. Parts of the Sierra Nevada received more than a foot of snow.

The weather service said scattered rain could continue through Tuesday in the southern part of the state. Another storm was expected to arrive on Thursday.
