A new Pineapple Express storm is poised to strike the Pacific Northwest, exacerbating flooding as the region continues to recover from recent heavy rainfall. This atmospheric river, drawing warm, moist air from Hawaii, is expected to unleash intense precipitation across western Washington, Oregon, and northwestern California through Wednesday. While higher elevations may see a mix of snow, with potential accumulation in the Cascades, the primary concern remains the heavy rain and its impact on already saturated soils.
