After more than 10 collisions this morning, the state Department of Transportation is advising caution on Snoqualmie Pass and has been issuing advisories either requiring or recommending traction tires and chains. Read the latest here.
Trooper Chris Webb of the State Patrol said heavy winds and cold temperatures created ice on the road this morning, causing vehicles to spin out and collide with other vehicles. All the crashes have been cleared.
Traction tires were advised for Stevens Pass in the afternoon. Check the latest conditions here.
Avalanche control is planned at Stevens Pass from 2 to 6 p.m. Sunday. Eastbound traffic will be stopped at milepost 58 at Scenic and westbound traffic will be stopped at milepost 64.5 at the summit.
