Pacific Northwest, December 12, 2025 – Intense rains that triggered catastrophic flooding across the Pacific Northwest have begun to ease, though authorities warn that floodwaters and overflowing rivers will continue to affect communities for several days.

The storm, fueled by an “atmospheric river” carrying moisture from the Pacific Ocean, forced tens of thousands of residents to evacuate in Washington, Oregon, and parts of British Columbia.

Evacuations and Damage

Western Washington faced the heaviest impact, with roughly 100,000 people under Level 3 evacuation orders. Authorities instructed residents south of Seattle and Tacoma to leave their homes as rivers breached their banks. Aerial images revealed farmland submerged and neighborhoods at risk.

In Orting, Washington, officials warned of a “significant threat to life and property”, while rescue teams worked to evacuate residents from homes near the Snohomish River.

Across the border, Abbotsford, British Columbia, saw hundreds of properties threatened, with five of six major highways leading in and out of Vancouver closed due to flooding, rockslides, and avalanche risks. The main highway connecting Vancouver and Seattle remains open.

Storm Overview

The atmospheric river brought more than 250 mm (10 inches) of rain to parts of the region, with effects reaching western Montana and northern Idaho. Though rainfall has subsided, high river volumes mean flooding risks persist.

“While drier weather looks to be in store for this area through the upcoming weekend, the major catastrophic flooding effects are likely to continue for several days across portions of western Washington State and northwestern Oregon,” said the US National Weather Service.

Officials report no casualties or missing persons so far, but the situation remains dynamic and hazardous. Authorities continue to monitor river levels and advise residents to follow emergency instructions.
