Area observations and highway web cams via the PA 511 website are showing locally dense fog across the area. Localized areas of dense fog were noted along portions of interstate 80, 81, 380, 476 and 84 among other locations. The dense fog is mainly confined to the higher elevations. Localized visibilities under 1/4 mile are likely to occur. If traveling tonight be prepared for rapid fluctuations in visibility and plan some extra time to reach your destination safely. Use low beam headlights and leave plenty of space between vehicles.
