Washington State – The first atmospheric river of the season is expected to bring heavy rain and gusty winds to Western Washington starting Friday afternoon. Residents across the Seattle area and surrounding regions should prepare for flooding, particularly along the coast and in low-lying areas, as rivers could rise rapidly. Gusts may create hazardous driving conditions along major highways, including I-5 and SR 101.
According to the U.S. National Weather Service in Seattle, rainfall amounts of 3 to 6 inches are likely along the coast and mountains through Sunday night, with up to 4 inches expected in the north interior. Coastal towns like Forks and Neah Bay could see the most rain, while Seattle will experience 1.5 to 2 inches.
The heaviest rain is forecasted for Friday evening through Saturday, creating risks for drivers. The combination of rain and wind could reduce visibility and cause ponding on roads, so commuters are urged to slow down and remain cautious. Power outages are also a concern due to wind gusts up to 25 mph in exposed areas.
By Sunday, the rain will begin to taper off, but rivers will remain high. Those living near riverbanks or in flood-prone zones should monitor emergency updates and prepare to evacuate if necessary. The Washington Department of Transportation advises checking road conditions before traveling.
Looking ahead to Monday, conditions will improve slightly with a chance of showers and temperatures in the mid-50s. However, the threat of flooding will persist in some areas due to runoff.
