Pendleton, Oregon – Freezing rain and light snow are creating slick travel conditions across parts of eastern Oregon and south-central Washington, prompting a Winter Weather Advisory through Thursday midday.
According to the National Weather Service in Pendleton, mixed precipitation will continue through noon Thursday, with ice accumulations up to one-tenth of an inch and additional snow totals up to two inches possible in affected areas. Even light ice amounts may result in hazardous road conditions, particularly on bridges and untreated surfaces.
The advisory covers the east slopes of the Washington Cascades and the Kittitas Valley, where freezing rain may leave a thin glaze on roadways, sidewalks, and parking lots. Travel impacts are most likely along major corridors including Interstate 84, Interstate 82, US-97, US-395, and nearby secondary roads.
Forecasters note that freezing rain is especially dangerous because it can be difficult to detect, increasing the risk of vehicle skidding and falls. Road conditions may deteriorate quickly during periods of steady precipitation, particularly during the morning commute.
Drivers are urged to slow down, increase following distance, and allow extra travel time. The National Weather Service recommends checking current conditions through the Washington State Department of Transportation and the TripCheck system before departing.
Residents are also advised to use caution when walking outdoors, as ice may accumulate on steps, sidewalks, and driveways. Power disruptions are not expected to be widespread, but localized issues remain possible if ice builds on trees or utility lines.
For commuters, delivery drivers, and early-morning travelers, the greatest risk is expected during the overnight and morning hours before temperatures rise above freezing.
Conditions are expected to gradually improve later Thursday as precipitation tapers off and surface temperatures increase, but officials caution that lingering icy spots may persist even after the advisory expires.
