Atmospheric River to Bring Storms to Pacific Northwest

After earlier storms, a strong, winter-like atmospheric river is forecast to bring heavy rain, high winds and mountain snow to Oregon and Washington from Nov. 13 into the weekend. Forecasts call for about 1 to 1.5 inches of rain in Oregon’s Willamette Valley and 2 to 2.5 inches near the coast and mountains; Eugene may receive about 0.7 inches each Friday and Saturday. Widespread river flooding is considered unlikely, but intense rain, runoff and clogged storm drains could cause localized flooding in low-lying areas, streets and streams. Gusty winds could bring down trees and cause power outages, while coastal areas also face high surf and sneaker-wave hazards. The relatively warm storm could bring 6 to 12 inches of snow above 6,000 feet, but major snowfall is not expected on Cascade passes.
