Heavy snow began falling at 6:30 p.m. Tuesday at Snoqualmie Summit, leading to spin-outs and crashes on Interstate 90 that forced state troopers to shut down eastbound lanes for hours.
A winter storm warning issued by the National Weather Service is calling for an additional one to 2.5 feet of snow over the next 24 hours.
Snow could fall at a rate of an inch an hour. WSDOT crews are working around the clock, plowing and treating the corridor to keep the road clear.
Officials know that many travelers will be headed over the pass in the coming days to visit friends and families for Christmas. WSDOT suggested drivers consider waiting until Thursday to try to cross the pass.
“This is a mountain pass. We’re in the mountains of the Cascades. We can get a lot of snow and a lot of rain. We can have a lot of changes real fast and any time,” WSDOT Superintendent, Terry Kukes said.
Officials say you should pack supplies if you are planning a trip over one of the passes. Take blankets, water, food, chains and other essentials in case of closures.
Also, WSDOT issued an alert for U.S. Route 2 over Stevens Pass for Wednesday morning: “Both directions to close at 9a Dec. 23, for avalanche control, which takes 30 min to 2 hrs”.
