A potent winter storm is causing major disruptions to travel and daily routines across the Northwest, including the Seattle metro area.
“Heavy snow can be expected through Saturday morning as a storm continues to dive southward and parallel the Washington and Oregon coastlines," AccuWeather Meteorologist Brett Rossio said.
Washington's Governor Jay Inslee declared a state of emergency on Friday ahead of the snowstorm.
Travel could be difficult to impossible across parts of the Interstate-5 corridor, including Siskiyou Summit in Oregon.
"Travel will be dangerous through Saturday as roads will be entirely snowcovered," Rossio said.
Travel may be difficult to impossible over Donner Summit, California, along I-80 at the height of the storm. Motorists should check on the situation before venturing out on their journey.
“The cold will also be dangerous for those who are not acclimated. Temperatures through Saturday night will run 10-20 degrees below normal," Rossio said.
