Oregon and Washington Cascades Face Up to 12 Inches of Snow Under Winter Weather Advisory
PORTLAND, OREGON — The National Weather Service (NWS) in Portland has issued a Winter Weather Advisory for the Oregon and South Washington Cascades, warning of heavy mountain snow and gusty winds through the weekend.
The advisory will be in effect from 11 a.m. Saturday through 5 a.m. Monday, as a cold storm system sweeps across the Pacific Northwest. Forecasters expect 6 to 10 inches of snow above 3,500 feet, with up to 12 inches or more above 5,500 feet in areas such as Government Camp, Santiam Pass, and Willamette Pass.
“Travel could become slick and hazardous, particularly on mountain passes and bridges,” warned the National Weather Service. “Motorists should be prepared for reduced visibility and blowing snow, especially at higher elevations.”
Strong Winds and Blowing Snow Expected
Winds are expected to gust up to 40 mph across the ridges and passes, creating blowing and drifting snow that could further complicate travel. The heaviest snowfall is expected from Saturday night through Sunday afternoon, gradually tapering off by early Monday morning.
Authorities are urging travelers to carry tire chains, blankets, flashlights, and winter emergency kits. Drivers should also check for updates before hitting the road — TripCheck.com for Oregon and WSDOT.com for Washington provide live updates on closures and chain requirements.
Cooler Weather for Lower Elevations
While mountain areas brace for winter conditions, lower valleys across Oregon and southern Washington will remain mostly rain-free. However, temperatures are expected to drop significantly, with highs only reaching the mid-40s to low 50s through the weekend.
Forecasters note that this system marks one of the first major winter weather events of the season, signaling a transition toward colder and stormier conditions in the Pacific Northwest.
“It’s time to prepare for winter travel,” said an NWS meteorologist in Portland. “Even if you’re not in the mountains, colder temperatures and early-season frost will be widespread next week.”
