SEATTLE -- Forecasters say two weather systems Monday and Tuesday will drop up to 3 feet of new snow in the Cascades by early Wednesday, making driving difficult through the mountain passes. Pass report
The heavy snow could impact travel in the passes and raise the risk of avalanches.
KING 5 meteorologist Rich Marriot advises travelers to head over the pass Monday morning, as conditions will worsen into the afternoon and evening. An Avalanche Warning will be in effect for the mountains beginning Monday afternoon. Heavy snowfall and rising freezing levels will keep the avalanche danger high through at least Tuesday.
The National Weather Service also forecasts snow in Eastern Washington, especially on the eastern side, including Spokane and Pullman where roads may by hazardous for commuters.
