The Northwest will see heavy precipitation from a series of storms over the next 10 days, according to meteorologists at the Climate Prediction Center (CPC). A highly active storm system in the Gulf of Alaska will send waves of unsettled air down the Pacific coast, which will trigger heavy rain, snow and coastal gales over much of western Washington, Oregon and northern California. Computer models suggest precipitation in the five-to-seven-inch range, particularly in the higher elevations of the Cascade and Sierra mountain ranges.

This series of storms poses a moderate threat of flooding, especially in higher areas and along the coast. Precipitation amounts should begin to taper off in the next six or seven days, making way for dryer, colder conditions in the Northwest. When the cold Alaskan air makes its way inland, there may be freezing temperatures at elevations as low as 4,000 ft.
