Wind and Rain in the Northeast; Atmospheric River to Impact the West

A cold front will cross the Great Lakes and Northeast U.S. through today with gusty winds and areas of rain showers. A strong atmospheric river is then expected to move into the Northwest by midweek bringing a threat for moderate to heavy rainfall and flooding, gusty winds, and mountain snows for parts of Washington, Oregon, northern California, and the Sierra Nevada.

Active weather returns late Monday, with stronger systems to follow Tuesday afternoon into Wednesday evening, and Thursday into Friday. The strongest of these fronts arrives late Tuesday and Wednesday with moderate to heavy rain, and strong southerly winds to the coast, East of the Cascades and in the Shasta Valley. Snow levels will be high. The third system arrives Thursday bringing additional rain and gusty winds to the area. Along the coast, high surf conditions are likely which combined with high King Tides are expected to bring dangerous beach conditions and a possibility of minor tidal flooding along low lying coastline and estuaries.
Strong, damaging winds are coming to the coast this afternoon. A High Wind Warning will be in effect for the Capes, Headlands and exposed areas near the Southern Oregon Coast. This includes areas near Bandon, Denmark, Port Orford, Gold Beach, and Pistol River. Downed trees and power lines could result in power outages. Stronger winds are expected Tuesday night and for the coast, Rogue Valley and Shasta Valley as well.
A High Surf Advisory will be in effect starting Tuesday evening with large breaking waves of 20-25 feet. This will begin south of Cape Blanco and will expand to all waters Wednesday evening before continuing through Thursday evening. King Tides will coincide with these waves, and the highest King Tides are expected to arrive around noon Thursday.
A series of fronts will bring periods of moderate to heavy rainfall across northern California and southern Oregon. Rainfall amounts will be highest over coastal terrain and western Siskiyou County. Snowfall is not a concern, as high snow levels will limit snowfall to the highest peaks and ridgelines. Small stream overflow and areas of nuisance ponding are possible. Visibilities may be limited while traveling. Roads may be slick where runoff is limited. Ponding water is possible where drainage is blocked.
