A Friday afternoon snow squall made Interstate 79 the scene of several vehicle accidents, according to on-scene responders.

According to the National Weather Service of Pittsburgh, a dangerous squall was detected at 12:30 p.m. near Cranberry. Dangerous road conditions for Interstate 79 and the Pennsylvania Turnpike were predicted.

At 12:40 p.m., a four-car crash was reported in the southbound lanes near mile marker 83.6. Justin Hart, assistant chief of Harmony Fire District, said one person was transported from the scene for minor injuries.

Hart said the crash was a chain reaction.

Five minutes after the first crash, several tractor trailers and vehicles crashed in the northbound lanes at mile marker 84.4. No one was transported from the scene.

Dispatchers said Harmony EMS, Adams Area Fire District, Cranberry Township Volunteer Fire Company, state police, Jackson Township police and UPMC’s squad 89 cleared the scenes in under two hours.
