Heavy rain and mountain snow across the northwestern U.S. this weekend

A Pacific storm system will continue to impact the West Coast through Sunday. Heavy rainfall could lead to flash flooding, river and small stream flooding, as well as mudslides and debris flows, especially over burn scars. At higher elevations, strong winds and heavy snowfall, with accumulations of 1 to 3 feet, could result in hazardous travel through mountain passes.
