In Northern California, tens of thousands are without power as a weekend storm slams the Pacific Northwest, dumping four-to-seven feet of snow on the Sierra region and leading to road closures. The National Weather Service also issued a winter storm warning for greater Lake Tahoe through 1 a.m. Tuesday and warned of widespread whiteout conditions and powerful wind gusts. The Sierra region can expect another two to four feet on Monday and there’s a foot coming Monday into Tuesday in the Wasatch Mountains in Utah. He said gusts in Lake Tahoe could top 100 mph on mountain ridge tops. As of Monday morning, there were more than 56,000 homes and businesses without power in California, 11,000 without power in Oregon and, at least 6,000 in Washington.
Moreover, Parkinson said there will be uncharacteristic, even record cold in the West. Monday’s high in Seattle should be just 24 degrees, which marks the coldest high ever there for this date, breaking the old record by 10 degrees. The cold will be felt as far south as Riverside, California, where the high won’t hit 50 degrees, which would be another record. There’s a massive cold air outbreak in Canada making its way down to the American West, Parkinson explains, meaning the region will be dealing with the cold through at least Wednesday. The National Weather Service reported 3.8 inches of snow fell in Seattle Sunday, where the wind chill caused temperatures that felt like they were near zero degrees. In Northern California, 29 inches of snow fell over a 24-hour period ending Sunday Morning. The National Weather Service in Reno said snow would remain heavy into Monday as the next storm pushes through the region.
However, several mountain roads were shut down on Sunday, including a 70-mile stretch of Interstate 80 through the Lake Tahoe region to the Nevada state line. On Sunday, the California Department of Transportation tweeted that there was low or zero visibility on I-80. The National Weather Service in Sacramento also warned on Sunday night that mountain travel will continue to be difficult if not impossible through tomorrow and predicted the best time to travel will be Thursday. The continuing storms were welcomed in parched California, where the Sierra snowpack had been at dangerously low levels after weeks of dry weather. But the state Department of Water Resources reported on Christmas Eve that the snowpack was between 114% and 137% of normal across the range with more snow expected.
