Pendleton, OR – Drivers across eastern Oregon are facing hazardous travel conditions tonight as dense fog settles over I-84 between Cabbage Hill and Deadman Pass, creating rapidly changing visibility for evening commuters.
According to the National Weather Service Pendleton office, webcams along the mountain corridor began showing fog and mist shortly after 6 p.m. Tuesday. Images from TripCheck cameras at Cabbage Hill, Deadman Pass, and Poverty Flats indicate sharp reductions in visibility, with headlights of passing vehicles barely visible through the low clouds.
The agency is urging drivers to slow down, use low beam headlights, and increase following distance while traveling through the affected stretch. Fog is most concentrated between mileposts 220 and 228, an area already known for steep grades and challenging winter conditions.
Transportation officials say the fog may thicken as temperatures cool overnight. Winds have remained light in the area, limiting air movement and allowing moisture to settle along the hill and into the canyons below.
No major crashes had been reported as of Tuesday evening, but officials warn conditions can deteriorate quickly. Truck drivers navigating the downgrade near Cabbage Hill should use extra caution, especially when approaching curves and ramps.
The National Weather Service expects patchy fog to continue into early Wednesday morning before slowly improving after sunrise. Travelers are encouraged to check TripCheck for live camera updates and road conditions before entering the pass.
