Snow- and ice-covered roadways are causing havoc on Interstate 90 today, with westbound lanes closed for a couple of hours near Ellensburg after at least two wrecks.
Even after I-90 was reopened about 10 a.m., drivers faced a white-knuckle drive over Snoqualmie Pass.
By noon, the Washington State Patrol was reporting whiteout conditions on some areas of the pass and recommended people reconsider driving Snoqualmie unless absolutely necessary.
The Washington State Department of Transportation reported 66 inches of snow has fallen at Snoqualmie Pass in the past four days.
Eastbound traffic also encountered problems about noon when three semis and a car collided about 13 miles east of the summit.
That wreck is currently blocking one lane.
In addition, one westbound lane was closed on I-90 near Vantage after a non-injury accident involving a semi and two cars. That wreck happened just after 8 this morning.
Snow continues to fall hard on Snoqualmie Pass and chains are required on all vehicles except all-wheel drive.
Meanwhile, Stevens Pass remains closed as Washington State Department of Transportation crews deal with dangerously bending trees and downed power lines. The pass has been closed since Sunday afternoon.
Blewett Pass is somewhat better, with traction tires advised and compact snow and ice on the roadway.
