Heavy rainfall is impacting Oregon and Southwest Washington significantly, leading to flood warnings and road closures. The Clackamas River, in particular, has risen dramatically, forcing many residents to evacuate.
Flooding in Oregon: Key Facts and Events
On December 19, 2025, the Clackamas River overflowed its banks, affecting areas southeast of Portland. Homes at the Carver Mobile Home Ranch in Damascus were partially submerged. Thousands in Clackamas County are under evacuation notices due to rapidly rising waters.
Rainfall and River Conditions
- Up to 4 inches of rain recorded over 24 hours.
- A flood warning remains in effect for Northwest Oregon and Southwest Washington.
- Concerns are particularly high for the Sandy River near Bull Run and parts of east Multnomah County.
According to Sebastian Westerink, a meteorologist with the National Weather Service in Portland, the rainfall amounts are a significant factor in the river’s rapid rise. “Those amounts are certainly contributing to the rapid rise of the river,” he stated.
Community Response and Evacuations
Local resident Curtis Gillette expressed deep concern for those affected by the flooding. “I feel tragic for the people that are dealing with it,” he shared, highlighting the urgent need for safety among those impacted.
Evacuation notices are in place across several areas, particularly for low-lying regions near the river. Residents are advised to prepare for potential mandatory evacuations.
Road Closures and Traffic Impacts
The flooding has also led to lane closures on key highways, including U.S. 101 and Oregon 6. Travel advisories recommend checking National Weather Service updates and state traffic cameras before setting out, especially during the holiday season.
Snow Forecast in the Cascade Mountains
In addition to flood warnings, winter weather advisories are active for the Cascade Mountain passes. Up to a foot of snow is expected, complicating travel conditions.
Ongoing Risks and Power Outages
As of Friday morning, several rivers in the region continue to rise. The Cowlitz River near Kelso, Washington, is one such example of ongoing flood risks. Power outages have affected thousands, with Portland General Electric reporting over 6,000 affected customers.
