PITTSBURGH, Pa. – Drivers across western Pennsylvania face treacherous conditions Wednesday morning as dense fog reduces visibility to less than a quarter mile. Morning commuters on the Parkway East and Pennsylvania Turnpike should expect slowdowns and potential hazards until the advisory lifts at 9 a.m.
According to the National Weather Service in Pittsburgh, fog blankets higher elevations in Fayette, Westmoreland, and Allegheny counties. Conditions are most dangerous before sunrise, with travel strongly discouraged in rural valleys where fog lingers. Officials urge motorists to use headlights, reduce speeds, and leave extra space between vehicles.
Rain and thunderstorms add to the challenge. Showers are expected through Wednesday afternoon with chances increasing toward evening. By Friday, a more organized system could bring heavy rainfall and minor flooding in low-lying areas. Cooler air will follow this weekend, hinting at the season’s first real taste of fall weather.
Localized flooding could affect Route 30 near Greensburg and Route 119 near Uniontown if rainfall totals push higher. Outdoor events and Friday evening football games may see delays due to lightning and wet fields.
While dangerous fog will ease by midmorning Wednesday, unsettled weather persists into the weekend. Residents are advised to prepare for wet commutes, keep phones charged, and check for updated advisories as conditions evolve.
