Lehigh County coroner Scott Grim says 17-year-old Robert Mills was riding an ATV in Wind Gap when he struck the tree around 9:30 p.m. Monday.
The teen was transported to a hospital and later pronounced dead. The cause of death was head injuries and Grim says it was ruled an accident.
The massive hybrid storm knocked down trees across a large portion of eastern Pennsylvania, blocking roads and knocking out power to more than a million customers.
