KNTV reported that a 100-foot (30-meter) redwood tree fell on a car in Saratoga, Silicon Valley, on Wednesday, trapping a child. Firefighters freed her with minor injuries. “We were very lucky,” Santa Clara County Fire Department Capt. Matt Mokhtarian told the TV station. “Just a few feet here.

Flash floods devastated southern Los Angeles County on Thursday. A automobile was submerged in a Long Beach underpass after cars plowed through water on low-lying roads. One white van was trapped at a crossroads near Seal Beach, south of Los Angeles, when Pacific Coast Highway floods blocked portions of the roadway on Thursday.

A Costa Mesa swift-water rescue crew plucked someone from a storm channel. On social media, the Orange County Fire Authority reported that the victim was hospitalized in stable condition.

A guy stuck on a tiny island in the Santa Ana riverbed by surging water was rescued by the fire department. A chopper dropped a paramedic to save the guy.

Sierra Nevada ski resort Mammoth Mountain recorded 12–14 inches (30–36 cm) of snow overnight. State authorities announced this week that the Sierra snowpack, which supplies 30% of California's water, was significantly below normal. The mountains east of Los Angeles received heavy snowfall.

The meteorological service office in Reno, Nevada, issued a winter storm warning for about 300 miles (480 kilometers) of the Sierra from north of Lake Tahoe to south of Yosemite National Park until Friday morning. Forecasters predict gusts up to 100 mph (160 kph) and snowfall rates up to 2 inches (5 cm) per hour.

The second atmospheric river, due late Saturday, is being called “the largest storm of the season” by the National Weather Service. As the storm pauses over Point Conception in Santa Barbara County late Sunday into Monday, it will be worse.

This system will likely produce 24 to 36 hours (or more) of continuous rain,” the weather agency projected Thursday. Southern California is anticipated to see mudslides and flooding from Monday to Wednesday due to heavy rain and snowfall at higher altitudes.
