Ten skiers remain missing, with six survivors confirmed after an avalanche in the Castle Peak area of Truckee that happened Tuesday morning.
The survivors remain at the avalanche site, awaiting rescue, with the remaining 10 still unaccounted for, according to a post on the Nevada County Sheriff's Office Facebook page.
The group consisted of four ski guides with 12 clients.
Search and rescue crews are continuing to search for the missing skiers 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 backcountry 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.
A mountain guide company operating out of Truckee issued a statement on its website on Tuesday night following the incident. That statement is provided in its entirety below.
Blackbird Mountain Guides is currently responding to a serious backcountry incident involving an avalanche that occurred this morning, February 17, near the Frog Lake huts in the Castle Peak area.
A total of 12 clients and four guides had been staying at the Frog Lake huts since February 15. The group was in the process of returning to the trailhead at the conclusion of a three-day trip when the incident occurred.
The leadership team at Blackbird Mountain Guides is working in full coordination with the Nevada County Sheriff’s Office and Nevada County Search and Rescue to support the ongoing rescue operation.
Blackbird Mountain Guides is in direct contact with the emergency contacts of the affected clients and guides and is providing them with regular updates as verified information becomes available.
California is being 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.
Several ski resorts around Lake Tahoe were fully or partially closed due to the extreme weather.
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.
Castle Peak, a 9,110-foot (2,777-meter) peak in the Donner Summit area of the Sierra Nevada, is a popular backcountry skiing destination. In the nearby town of Soda Springs, at least 30 inches (76 centimeters) of snow had fallen in the last 24 hours, according to the Soda Springs Mountain Resort.
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.
In January, an avalanche in the region buried a snowmobiler in snow and killed him, authorities said. Each winter, 25 to 30 people die in avalanches in the U.S., according to the National Avalanche Center.
