Roslyn, Washington – Heavy snow stacking up above 5,000 feet could make overnight travel across the Cascade Crest treacherous, with up to 20 inches falling before conditions ease Monday afternoon.
According to the National Weather Service in Pendleton, a Winter Weather Advisory remains in effect for the Upper Slopes of the Eastern Washington Cascades Crest until 4 p.m. Monday. Additional snowfall of 14 to 20 inches is expected above 5,000 feet, with 4 to 8 inches around pass levels. Periods of moderate to heavy snowfall will intensify at times, especially overnight.
Across central Washington, warmer daytime road temperatures may limit accumulation on the most traveled highways, but conditions will deteriorate quickly after sunset. Snow-covered pavement and slick stretches are likely near Snoqualmie Pass along I-90, as well as routes near Easton and Roslyn. Visibility may drop sharply during heavier bands.
Transportation officials warn that nighttime travel will pose the greatest risk, as steady snowfall outpaces melting on road surfaces. Mountain travelers should carry chains, pack winter supplies and check conditions before departure.
Drivers can monitor real-time updates through the Washington State Department of Transportation website. The advisory remains in place until 4 p.m. Monday, and additional updates are possible if snowfall rates increase.
