Pacific Northwest Braces for Extensive Flooding
Residents across the United States Pacific Northwest and parts of Canada are preparing for widespread flooding. An atmospheric river event is delivering heavy rainfall, leading to elevated river levels and the potential for record-setting floods.
The U.S. National Weather Service has issued warnings of potential catastrophic flooding in Oregon and Washington, specifically along the Skagit and Snohomish rivers. In Canada, major highways connecting to Vancouver have been closed due to inundation, debris, and the risk of avalanches. Evacuation orders are currently active for thousands of individuals in both nations, with additional rainfall projected for Thursday.
Impact in Washington State
On Wednesday, Washington State Governor Bob Ferguson declared a statewide emergency. Estimates suggest that up to 100,000 residents could face evacuation orders. The emergency declaration highlighted that ongoing rain combined with snowmelt at higher elevations is expected to intensify flooding conditions. Potential severe impacts on supply chains and transportation infrastructure were also noted.
- Skagit County: This significant agricultural area, located north of Seattle, has implemented immediate evacuation orders for residents residing within the floodplain. Authorities estimate approximately 75,000 people may need to evacuate from low-lying areas along the Skagit River.
- Snohomish County: The Snohomish County Sheriff's Office reported multiple helicopter rescues of individuals stranded in their homes in Sultan, Washington, approximately 65 kilometers (40 miles) northeast of Seattle. On Thursday morning, officials indicated that the eastern region of the county is the most affected. The Skykomish River crested above 7 meters (24 feet) overnight, nearing a record level. The Snohomish River is also experiencing significant flooding, with water levels approaching local flood wall limits.
- Road Closures: Officials in King and Snohomish counties have confirmed numerous closures on state and local roadways, with more anticipated throughout Thursday.
