Landslides and fallen trees on State Route 16 at Anderson Hill Road in Gorst buried a service truck under branches and mud on Thursday.
Washington State Patrol Trooper Katherine Weatherwax said no one was inside of the truck at the time.
An atmospheric river has brought steady rain to the Puget Sound region, bringing with it increased chances for landslides and avalanches. Wet conditions are expected to continue through Friday.
If you encounter potential hazards in or near the roadway, WSP says you should call 911.
