Winter weather in Pittsburgh can lead to hazardous conditions, including icy roads and sidewalks due to thawing and refreezing cycles. Wind chills can significantly lower the perceived temperature, increasing the risk of frostbite and hypothermia for those exposed to the cold for extended periods. Lake-effect snow, while less frequent than in areas closer to the Great Lakes, can still result in significant snowfall, potentially disrupting travel and daily activities. Residents and businesses should also prepare for possible power outages during winter storms.
