PACIFIC NORTHWEST — A powerful atmospheric river is moving into Oregon, Washington, and parts of Idaho tonight, bringing the risk of flooding, landslides, damaging winds, and significant mountain snow through Thursday. Forecasters warn that this system will concentrate its heaviest impacts on western Oregon, where the most intense rainfall bands are expected to set up.
Heavy Rain Targets Western Oregon and Western Washington
According to early projections, the western Oregon lowlands will receive 1–3 inches of rain, with isolated pockets reaching 4–6 inches. Farther north into southwestern Washington, totals of 1–2 inches are expected from the coast inland through the Puget Sound region and into the northwest interior.
Rainfall rates may increase overnight, heightening the concerns for localized flooding and landslide activity, especially where soils remain saturated from earlier storms.
