Link to conditions on Snoqualmie pass

We have this in the wife's electronic intel collection kit so we'll check as we hit Spokane and further west if connection is available.

Traction tires in Washington means M+S or snowflake marking on sidewall with 1/8" tread depth.
4WD doesn't require chains if all 4 tires are traction tires but chains must be carried anyway(?????) Passenger cars might have to chain up.

My folks tell me there have been problems on Snoq this year as it's been pretty wet vs past years.

The route thru the Columbia Gorge is about 250 miles farther than going over the pass if you break off at Ritzville. If you go further west before diverting it would be even more mileage.
