Winthrop, WA – Drivers traveling through Washington's North Cascades could encounter snowy roads and brief winter driving conditions Monday night, November 9, into Tuesday, November 10, as a mountain weather system brings up to 4 inches of snow to higher elevations.
According to the National Weather Service in Spokane, light snow is expected across portions of the Cascades and far northern Idaho, with the greatest accumulations forecast near Washington Pass at elevations above 5,000 feet.
Monday Night, November 9: Mountain Snow Develops

Forecasters anticipate between 1 and 4 inches of accumulation in the Cascades above 5,000 feet, with Washington Pass identified as a primary area of concern.
Motorists traveling through the pass could encounter periods of snow covered pavement, reduced traction and changing road conditions.
Lower elevation communities are not expected to experience the same snowfall totals.
Tuesday, November 10: Winter Travel Conditions Continue
Snow chances will persist into Tuesday afternoon, potentially creating brief periods of difficult travel through the higher mountain passes.
The National Weather Service specifically highlights Washington Pass as an area where winter driving conditions could develop.
Travelers should check Washington State Department of Transportation road reports before crossing the North Cascades and carry appropriate winter supplies.

Far northern Idaho's Selkirk Mountains could receive up to 1 inch of snowfall during the same period.
The snowfall is expected primarily in higher elevations, with colder conditions affecting hikers, hunters and other outdoor recreation enthusiasts.
