With most passes expected 1-2 feet of snow, a leash and possibly closure may be required.
SEATTLE — Editor’s Note: The video above is from January 2022.
The mountains across the Cascades are expected to see up to 2 feet of snow over the next few days.
Before you go over the mountains, make sure to check the pass conditions as there can be closures and sometimes a leash may be required.
The Washington State Department of Transportation may close one or both directions of the pass if inclement weather or a collision necessitates closure.
Here’s how to check if the passes are open or closed in each direction before you hit the road:

A major reason passes are closed is to allow specialist teams to eliminate the risk of avalanches by bringing down accumulated snow in a controlled manner.
The Washington State Department of Transportation says it has about half a dozen slides that it monitors at Snoqualmie Pass to detect potential avalanches.
Chutes are natural areas of steep, often treeless terrain where snow accumulates. Under certain circumstances, snow may suddenly fall and fall.
Both Stevens and Snoqualmie have howitzers available for avalanche control. When the weather is clear, they can drop explosives from helicopters.
For the most part at Snoqualmie, bags of explosives are moved along wires called trams to the top of the slide, sometimes dropped from the ridges above.
However, it is not just a matter of where or how much snow falls. What keeps avalanche control teams busy is how quickly the snow falls.
