LOS ANGELES – After unleashing heavy rains and causing the tragic deaths of at least six individuals, a formidable atmospheric river system has largely passed through California. However, its aftermath still poses risks as thunderstorm activity continues to threaten Los Angeles County with potential mudslides, particularly in regions recently impacted by wildfires.

Weather advisories remain active until Sunday afternoon for the counties of Los Angeles, Ventura, and Santa Barbara, as scattered showers may still occur following the intense downpours experienced on Friday and Saturday.

The National Weather Service warned in a Sunday update, “Given the significant rainfall over the past few days, it won’t take much more to trigger additional flooding or rockslides.”

On Sunday, efforts continued to locate a 5-year-old girl who was pulled into the ocean by 15-foot waves at a Monterey County state beach on Friday. Her father, 39-year-old Yuji Hu from Calgary, Alberta, tragically lost his life in an attempt to rescue her, according to sheriff’s reports.

In another incident in Sutter County, located north of Sacramento, a 71-year-old man lost his life on Friday when his vehicle was carried away by floodwaters on a submerged bridge, as reported by 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.

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 (10 centimeters) 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.
