The Oregon Department of Emergency Management (OEM), the Department of Land Conservation and Development (DLCD), and the Oregon Department of Geology and Mineral Industries (DOGAMI) are urging residents and visitors to remain vigilant as landslide hazards increase across western Oregon, particularly in Lincoln County, where a significant landslide event continues to pose serious safety risks.
The landslide on HIghway 229 north of Siletz, which began on December 12, has destabilized the terrain in the affected area. The ground remains highly unstable, and the approaching atmospheric river is expected to worsen conditions. Oregon Department of Transportation geologists and engineers have been conducting aerial assessments using LIDAR and drone technology but have not been able to safely enter the site due to ongoing ground movement.
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 in Oregon will be Thursday and Friday, then will shift further south during the weekend. Heavy rainfall may trigger landslides and debris flows, especially in steep terrain and areas affected by recent wildfires.
- Stay alert to changing conditions. Monitor weather updates via radio, TV, or weather.gov/pqr.
- Listen for unusual sounds like cracking trees or rumbling rocks.
- Watch water sources for sudden changes in flow or color.
- Travel cautiously, especially at night. Assume roads may be compromised.
