Seattle, Wash. – Rain is expected to make a stronger return to the Pacific Northwest next week as a wetter-than-normal pattern sets up across Washington and Oregon. The National Weather Service outlook shows an increased chance of above-average precipitation from September 20 through September 26, bringing relief to dry late-summer conditions.
According to NOAA’s Climate Prediction Center, the region will likely see multiple systems tracking inland from the Pacific, pushing rain across the coastal ranges, Puget Sound, and the Cascades. While the outlook does not guarantee daily rain, it points to a higher probability of recurring wet periods, particularly for western Washington and northwestern Oregon.
Seattle, Tacoma, and Portland could see rain totals stack up enough to dampen commutes and impact weekend outdoor plans. Higher elevation areas of the Cascades should expect more sustained rainfall, helping to improve streamflows and reduce lingering wildfire risk. Eastern Washington and Oregon may stay drier, though showers are possible at times.
Forecasters say temperatures across the Northwest should hover near seasonal norms, keeping conditions mild compared to the widespread heat expected across much of the U.S. Residents are advised to keep rain gear handy and prepare for slick roads during the morning and evening rush.
Showers are expected to continue off and on through late next week, with additional updates possible as individual storm systems line up offshore.
