Crews search for backcountry skiers after avalanche reported in California mountains

SAN FRANCISCO (AP) — Search and rescue crews were looking for multiple backcountry skiers feared missing Tuesday after a reported avalanche in Northern California as a powerful winter storm moved through the state, authorities said.

The Nevada County Sheriff's Office received a 911 call at about 11:30 a.m. reporting an avalanche with people buried, said Ashley Quadros, a department spokesperson.

The sheriff’s office, the sheriff’s Search & Rescue team and a crew with the California Department of Forestry and Fire Protection responded to the area of Castle Peak, which is northwest of Lake Tahoe, Quadros said.

"It has been reported that a group of back country skiers was involved in the incident, with several members of the party missing at this time,” the sheriff’s office wrote in a Facebook post.

California was walloped this week by a powerful winter storm carrying treacherous thunderstorms, high winds and heavy snow in mountain areas.

According to the Sierra Avalanche Center based in Truckee, the area in the Central Sierra Nevada, including the Greater Lake Tahoe region, was facing high avalanche danger in the backcountry with large slides expected to occur Tuesday and into Wednesday.

The dangerous conditions were caused by rapidly accumulating snowfall, weakening snowpack layers and gale-force winds. Ski areas or highways where avalanche mitigation programs exist were not expected to be at as high of a risk, the center said.

Forecasters said the western slope of the Sierra Nevada in northern Shasta County — including portions of Interstate 5 — and parts of the state’s Pacific Coast Range could see up to 8 feet (2.4 meters) of snow before the storm moves through late Wednesday.

The storm wreaked havoc on roadways spanning from Sonoma County to the Sierra Nevada. Traffic was halted temporarily in both directions on I-80 near the Nevada state line due to spinouts and crashes, the California Department of Transportation reported.
