Travel across the Washington Cascades may become difficult this week as snowfall intensifies at Snoqualmie Pass and surrounding mountain locations, according to the National Weather Service.
The National Weather Service office in Pendleton has issued a Winter Weather Advisory for Tuesday evening through Wednesday evening, predicting snow accumulations of up to 10 inches along the higher east slopes of the Washington Cascades. Locally heavier snowfall is possible near higher peaks and ridgelines.
Snow is forecast to fall Tuesday and Wednesday, with the heaviest snowfall occurring throughout the day on Wednesday. Snowfall rates might range from moderate to heavy at times, substantially decreasing visibility and resulting in slick, snow-covered roads.
Snoqualmie Pass, a significant transport corridor that connects western and central Washington, is included in the alert. Officials warn that driving conditions can suddenly deteriorate, particularly during periods of heavy snowfall.
The advisory was issued Monday, as forecasts expressed growing confidence in significant snow totals throughout the passes. Travel interruptions are anticipated as personnel try to clear roadways amid the continuous snowfall.
Drivers going to cross the Cascades should check the current road conditions before leaving and be prepared for winter driving. The Washington State Department of Transportation suggests carrying traction devices, allotting extra travel time, and monitoring pass reports via its TripCheck and travel information platforms.
The National Weather Service classifies the overall weather risk as moderate but warns that conditions could worsen if snowfall surpasses forecasts or temperatures remain lower than expected.
Motorists should slow down, increase their following distance, and be attentive for rapidly changing conditions. Travelers are also advised to postpone unnecessary journeys during the heaviest snowfall periods whenever feasible.
