Oregon Department Of Emergency Management Activates Emergency Coordination Center To Level 3 In Response To Atmospheric River - 12/17/25
SALEM, Ore. – The Oregon Department of Emergency Management (OEM) has virtually activated the State Emergency Coordination Center (ECC) to Level 3 – Regional Response as of 4:00 p.m. on Wednesday, December 17, 2025, in response to an incoming atmospheric river expected to bring heavy rainfall, potential flooding, and increased landslide risk across western Oregon. The ECC will be supported with representatives from key state agencies to ensure streamlined communication, coordination, and resource support for impacted communities.
Flood Watch and Landslide Risk Across Western Oregon
The National Weather Service has issued a Flood Watch through Thursday night for multiple counties, including Benton, Clackamas, Clatsop, Columbia, Hood River, Lane, Lincoln, Linn, Marion, Multnomah, Polk, Tillamook, Washington, and Yamhill. The heaviest rainfall is expected Thursday and Friday, with conditions shifting south over the weekend. Saturated soils and steep terrain, especially in areas recently affected by wildfires, may lead to landslides and debris flows. This will be accompanied by high wind gusts along the coast, in the coastal mountains and some inland areas.
Stay alert and take precautions: Turn Around, Don’t Drown
- Be aware of limbs that may have come loose in the windstorm and be cautious of falling branches. Make sure outdoor furniture and decor is secured.
- Listen for unusual sounds such as cracking trees or rumbling rocks.
- Watch for sudden changes in water flow or color.
- Travel cautiously, especially at night. Assume roads may be compromised.
- Do NOT drive or walk through flood waters. There are unseen hazards like open storm drains and metal debris, and cars can be swept away in even a few inches of water.
- Understand the additional burn scar risks.
- The Oregon State Fire Marshal’s Office urges you to be careful using alternative power sources during power outages.
