Washington state is currently under a state of emergency following a series of torrential rainstorms that have resulted in significant flooding, mudslides, and evacuations. As of Thursday, December 11, 2025, tens of thousands of residents have been ordered to evacuate due to rising water levels in rivers and the threat of mudslides on highways. The National Weather Service reported that some areas in the Cascade Mountains received up to 6 inches (15.2 centimeters) of rain within a 24-hour period, with Snoqualmie Pass recording an additional 1.7 inches (4.3 centimeters) in just six hours.

Governor Bob Ferguson declared the emergency on Wednesday, emphasizing the potential risk to lives in the coming days. Skagit County, a key agricultural region north of Seattle, has mandated evacuations for all residents within the floodplain of the Skagit River. In Mount Vernon, teams are actively informing residents in low-lying areas about evacuation notices, while firefighters have conducted rescues in Sumas, where several individuals were trapped in their homes.

By midday Thursday, nearly 16,000 customers were without power, and major roadways, including a mountainous section of U.S. 2, remained closed due to debris. Projections indicate that the Skagit River may crest at approximately 42 feet (13 meters) in Concrete and 39 feet (12 meters) in Mount Vernon, both of which would set new records for flooding in the area. Local officials are urging residents to heed evacuation orders, as the potential for catastrophic flooding remains a concern.

The flooding situation in Mount Vernon is particularly critical, as the city has a history of flood-related disasters, including significant displacements in 2003. A floodwall constructed in 2018 has provided some protection, but concerns persist regarding the effectiveness of existing levees. Business owners and residents are taking precautionary measures, such as stacking sandbags, to mitigate potential damage.

Meteorologists have attributed the intense rainfall to an atmospheric river phenomenon, which is characterized by a concentrated stream of moisture from the Pacific Ocean. The ongoing climate crisis has been linked to an increase in the frequency and intensity of such extreme weather events, raising concerns about future resilience and preparedness in the face of climate-related disasters. Another storm system is anticipated to bring additional rain starting Sunday, further complicating recovery efforts.
