Overview
- Washington remains under a state of emergency with tens of thousands under evacuation orders, including about 78,000 directed to leave the Skagit River floodplain.
- The Snohomish River topped its record by roughly a foot and the Skagit set a new crest at Mount Vernon as bridges and low-lying areas went under water.
- Helicopters and boats pulled residents from rooftops in Sumas, the U.S. Coast Guard rescued dozens, and erosion along the Nooksack led to at least two home collapses.
- A landslide blocked part of Interstate 90 east of Seattle, the Sumas border crossing was closed, Amtrak halted service between Seattle and Vancouver, and more than 20 roads in 11 counties were shut.
- The Weather Prediction Center expects additional atmospheric rivers starting Sunday with a strong level‑4 event Monday and another system by midweek, heightening the risk of renewed flooding on saturated terrain.
