Snow and ice greeted drivers in Puget Sound’s higher elevations and mountain-pass highways Thursday morning, with snow showers in much lower

elevations than early forecasts predicted. WSDOT closed I-90 over Snoqualmie Pass and a portion of SR 18 near Tiger Summit during afternoon hours due to heavy snow, spinouts and collisions. Both roadways are now open.

There could more snow to come in the overnight hours, and drivers should prepare for winter driving and possible black ice Friday morning.

And then Washington drivers can expect a quick breather before readying for the next round: a heavy storm forecast to hit the mountains and most of Eastern Washington late Saturday. Snow is also possible Saturday in Western Washington’s higher hills.

“Those on the road early Friday and late Saturday and Sunday should be prepared. Take it slow and carry chains,” said Chris Christopher, WSDOT.

director of maintenance operations. “Our crews will be out all over the state, but drivers need to plan ahead and take precautions.”

On Snoqualmie Pass, close to 20 equipment operators will work over the weekend to keep I-90 safe and open. For more on WSDOT’s winter operations visit www.wsdot.wa.gov/winter.

Before you go, check the WSDOT Web site and local media reports. It is also important to check the mountain pass reports www.wsdot.wa.gov/traffic passes/ for any scheduled road closures for avalanche control.

Drivers should be prepared, carry chains, slow down and schedule extra time to reach your destination safely. Slow down when approaching intersections, off-ramps, bridges or shady spots. These all have potential to develop black ice that makes driving hazardous.
