SEATTLE — The avalanche danger from warming temperatures has prolonged the closure of Interstate 90 over Snoqualmie Pass.
The Transportation Department closed Washington’s main east-west highway Sunday night, and it remains closed into Monday afternoon.
Spokesman Bart Treece said the department hopes to reopen Snoqualmie Pass by 4:30 p.m., after another round of bringing down and clearing avalanches. He said recent layers of heavy snow are unstable because of the climbing temperature.
U.S. 2 over Stevens Pass also has been closed at times Monday for avalanche control. Meanwhile, Highway 12 over White Pass remains open with traction tires advised.The National Weather Service says the Spokane area will see more snow Monday morning before it turns to freezing rain and just rain later in the day.
Meanwhile, The Weather Service recorded nearly 5 inches of snow at Spokane International Airport from the storm.
KXLY reported the city of Spokane declared a Stage 1 snow event over the weekend and asked residents to move parked cars off arterials and bus routes to help snow plows.
Significant snow also fell elsewhere in Eastern Washington and northern Idaho with amounts varying by location and elevation.
Forecasters warn that roads will remain icy and slushy before warmer air moves into the region Monday.
