Pendleton, OR – Snow is moving into eastern Oregon and southeast Washington tonight, with accumulations of 5 to 10 inches expected in higher elevations through Wednesday, creating hazardous travel conditions across key mountain routes.
According to the National Weather Service in Pendleton, snow will be common along the eastern slopes of the Oregon Cascades and the Northern Blue Mountains beginning overnight and lingering through midday Wednesday. Periods of light to moderate snowfall may reduce visibility to less than one mile at times, particularly overnight and early morning.
Forecasters say locally higher amounts are possible in higher terrain. Roads are expected to become slick, especially during nighttime hours when temperatures drop and snow accumulates more efficiently.
Impacted routes include Interstate 84 in the Blue Mountains, U.S. Highway 20, and Oregon Highway 204, as well as Santiam Pass. Drivers traveling between Pendleton, La Grande, Baker City, and central Oregon should allow extra time and prepare for winter driving conditions.
The advisory remains in effect from Monday morning through midday Wednesday. Officials urge travelers to check current road conditions through ODOT or WSDOT before heading out and to carry emergency supplies if crossing mountain passes.
Motorists should leave extra distance between vehicles, follow traction and chain requirements, and be prepared for changing weather conditions.
