A light dusting of snow that fell overnight, coupled with icy patches on roadways from yesterday's snowfall that melted and froze again, has caused many slick spots in the predawn hours today.
Motorists should pay particular attention to elevated roadways and bridges on highways across southwestern Pennsylvania. Additionally, the light snow in some spots has blown onto roads, creating more slippery hazards.
KDKA-TV was reporting numerous accidents caused by icy road conditions, including two crashes on Route 65 in the city's North Side. Numerous weather-related accidents were being reported in and near Pittsburgh, among them were crashes on the Birmingham Bridge and at Butler Street near the Pittsburgh Zoo. A crash involving two tractor trailers was reported on the Fleming Park Bridge leading to Neville Island.
Temperatures across the region are in the 20s with winds from the west-northwest at less than 10 mph.
In Pittsburgh and the immediate suburban areas, no watches, warnings or advisories were in effect at 5 a.m. Travelers heading north should take note that the National Weather Service has posted a lake-effect snow warning for Erie and Crawford counties until 9 a.m.
