In the state of Washington, this weekend's storm dumped almost a foot of snow in some places.
Snoqualmie Pass is a mountain pass that carries Interstate 90 through the Cascade Range. The pass summit is at an elevation of 3,022 feet.
Authorities say Interstate-90 was in pretty good condition Saturday night (11/16) where the roads were only slightly wet with some slush.
But temperatures in some places dropped into the 20s overnight (Saturday 11/16 into Sunday 11/17) and that means black ice was possible on the roads.
A snowplow worked overtime clearing the parking lot at a summit gas station. Drivers say the climb to the top wasn't€™t too bad as long as you don't exceed the speed limit.
Shannon Loomis and her family were headed to the Tri-Cities. She says if you follow her rules of the road, drivers will make it over the mountains in one piece.
Drivers heading over the pass to the Seahawks game on Sunday will still need to pack chains and patience as more snow is in the forecast.
