A weather system moving in overnight will bring advisory levels of snow accumulation to a majority of our Oregon zones, as well as the Blue Mountain and Blue Mountains Foothills zones of Washington. These conditions could impact travel times, reduce visibility, and make surfaces slick. In the Grande Ronde Valley and the Oregon Blue Mountains Foothills the snow will combine with high winds and heavily impact visibility with blowing snow and cause drifting. Make sure to check the forecast and road conditions before you travel.
