A series of storm systems will bring rain, snow, and wind to the Pacific Northwest through early next week. A low-pressure system from the northeast Pacific is already making landfall, with an atmospheric river expected to impact the region. Snow levels will drop early Sunday, affecting the Cascades through Monday, where a Winter Storm Warning is in effect due to heavy snow and challenging travel conditions. Meanwhile, heavy rain will increase flooding risks, particularly in lowland areas. Winds gusting up to 60 mph and wet weather are expected to persist, with a brief break in precipitation on Tuesday before more storms move in.
