Fog and stratus banking up against the northern Blue Mountains of Oregon are creating areas of reduced visbilities down to a quarter mile. This is especially noted along I-84 near Cabbage Hill and Poverty Flats, and is likely impacting Oregon State Route 204 at this time. These areas of reduced visbilities are expected to continue for several hours.
Patchy dense fog has begun to filter along the Oregon State Route 11 travel corridor, especially near Weston and Athena. Visibilities down to a quarter mile are possible, with the fog expected to lift in the next couple of hours.
