Strong Atmospheric River Bringing Heavy Rain to the Pacific Northwest; Areas of Snow in the North-Central and Eastern U.S.

Accumulating snow is expected over parts of the central Appalachians and Mid-Atlantic today as well as the Upper Midwest and the Upper Great Lakes this evening into Tuesday. Read More >

Active Weather Ahead

Gusty southwesterly winds will increase Monday and peak during the late afternoon and evening hours with sustain winds 20-35 mph and gusts 40-55 mph across Eastern Washington and North Idaho.

Following a very active weekend, we are monitoring the potential for a stronger atmospheric river to bring heavy mountain rain, warmer temperatures, and breezy winds across the Inland Northwest. Our primary concern is the combination of heavy rain and warmer temperatures in the mountains. This may lead to snowmelt on mid-to-lower slopes, which would increase the risk of rock and mudslides in steep terrain, particularly in the North Cascades and North Idaho. You may also see water levels rise on small creeks and streams.
