Pittsburgh, PA – Dense patchy fog is reducing visibility to less than a quarter-mile in spots during the Tuesday morning commute, creating hazardous travel conditions across parts of southwestern Pennsylvania and nearby Ohio. Drivers on key routes should exercise caution until the fog dissipates later in the morning.
According to the National Weather Service in Pittsburgh, visibility has dropped below 0.25 miles on several highways, including US-22 in Indiana County and I-70 near Zanesville, Ohio. Fog is also thick around I-470 near Wheeling, West Virginia. Officials advise motorists to slow down, use low beam headlights, and maintain safe following distances.
The fog is expected to clear by mid-morning as temperatures rise, improving travel safety. PennDOT and Ohio DOT crews are monitoring conditions closely, urging commuters to plan extra travel time and avoid non-essential driving until the fog lifts.
This patchy fog event follows several recent humid mornings and is typical for mid-July across the tri-state area. Warnings remain in effect through about 10 a.m., with updates possible if visibility issues persist.
