An atmospheric river brought heavy rain, flooding, and record warmth to the Pacific Northwest. This led to rail travel being suspended between Seattle and Portland and road closures across Washington due to potential landslides and floods. The combination of swift snowmelt in the mountains and warm air from atmospheric rivers increased flooding and led to significant flooding of low-lying areas. The small town of Forks saw a significant increase in rainfall, and the Coast Guard rescued five people from flooding near Rosburg. Although river flooding persisted, no rivers were in major flood stage. Seattle set a new rainfall record for Monday, and significant impacts were expected to continue through Wednesday. The flood led to services on the Port Townsend-Coupeville ferry route being discontinued.
