Powerful California blizzard shuts down roads and ski resorts as heavy snow and fierce winds slam mountains
(CNN) — Blizzard conditions continued to slam Northern California over the weekend with damaging winds and heavy snow dumping on mountain ridges down to the valleys.
Around 6.5 million people are under winter weather alerts across the Mountain West, with blizzard warnings still in effect for the Sierra Nevada.
The most extreme conditions are unfolding at the highest elevations, with whiteout conditions and hurricane-force winds in the Sierra Nevada.
NWS Sacramento reports dozens of inches of snow fell in multiple areas, the most at Sugar Bowl where 87 inches of snow fell.
The Tahoe area saw around 60 inches of snow.
The snow has closed a 70-mile stretch of Interstate 80 near the Nevada state line for more than a day after highway officials reported stranded drivers Friday night.
“Extremely heavy snowfall rates of 2-6 inches an hour combined with very strong winds exceeding 100 mph at times will maintain impossible travel conditions in the Sierra Nevada,” the Weather Prediction Center said.
The weather service has warned of “high to extreme” avalanche danger through Sunday afternoon in the Central Sierra and Greater Lake Tahoe area.
About 5-12 feet of snow was forecast to fall along the crest of the Sierra by late Sunday, while damaging wind gusts “possibly in excess of 75 mph” could be expected across the Intermountain West, according to the Weather Prediction Center.
“These winds will likely down trees and power lines, resulting in widespread power outages,” it said. “Moreover, cooler temperatures will usher into the West behind the initial front, lowering the snow levels down into many valleys.”
More than 12,000 homes and businesses were without power in California early Sunday – down from nearly 40,000 that morning, according to the tracking website PowerOutage.us.
Numerous ski fields and chairlifts were also closed Saturday, including at Palisades Tahoe, Sierra at Tahoe and Mammoth, with some resorts warning of delayed starts on Sunday.
The ski resort Sierra-at-Tahoe in Twin Bridges shared images with CNN of snow piling up against the door of the resort’s maintenance shop and a car in the resort’s guest parking buried in snow that fell overnight.
“Winds will wane in intensity, though some additional heavy snowfall is expected through the day, particularly for the southern Cascades/Sierra, Wasatch, and central Rockies,” the National Weather Service said in its latest forecast discussion early Sunday.
The storm will begin to wind down later on Sunday, but will be followed a new system on Monday, the weather service said.
Whiteouts and ‘impossible’ travel conditions
Extreme snowfall and roaring winds in the Sierra and parts of the northern ranges mean blowing snow and whiteout conditions making travel “impossible,” the National Weather Service warned.
The storm forced the closure of the main road to Mammoth Mountain ski resort, US 395, for hours Saturday due to whiteout conditions, according to the California Department of Transportation.
And California Highway Patrol Truckee announced that I-80 was still closed as of Saturday evening between the Nevada state line and Colfax.
The snowy and windy conditions left some vehicles stuck on the road on Friday, with some motorists in need of rescue, according to CHP Truckee, which reported a “mass amount of vehicles stuck over Donner Summit.”
“At one point, emergency personnel and tow trucks had a difficult time getting to motorists due to blizzard conditions,” the agency said.
Many other roadways in the area are closed due to the weather and some are being chain controlled, requiring vehicles to have chains to proceed on the roadways.
California Highway Patrol posted Saturday afternoon a photo of one of its cars stuck in snow. “Even our officers sometimes get stuck in the snow! The blizzard-like conditions have yet to let up, but nonetheless, our officers are working hard to keep everyone safe. Avoid travel during this time and stay updated on road conditions,” it said on Facebook.
