The atmospheric river, some 5,000 miles long, could dump a whopping 9 feet (almost 3 meters) of snow on the tops of the Cascade mountains, according to the weather service.
As much as 15 inches of rain is forecast farther down the mountains, while several inches of rain could inundate those areas closer to sea level, including Portland and Seattle.
