Overview
- At 1:34 a.m., the National Weather Service issued the advisory for the lowlands of Benton, Linn and Lane counties in the Willamette Valley.
- Visibility may drop to one quarter mile or less, creating dangerous conditions for the morning drive.
- Drivers are urged to slow down, use low-beam or fog lights, avoid high beams and leave extra following distance.
- If visibility nears zero, officials advise pulling into a safe parking area with hazard lights on; if none is available, stop well off the roadway and keep only hazard flashers on.
- Conditions typically improve by mid- to late-morning, and a separate advisory in Oregon’s Lower Treasure Valley was already becoming patchy and allowed to expire around 9 a.m.
