One person was killed and at least nine others injured by lightning at the Pocono Raceway on Sunday.
Two of the unidentified people were transported to a nearby hospital by ambulance. There has been one confirmed fatality according to WBRETV Eyewitness News.
Typically injured people are transported from the track by helicopter, but the storm conditions would not allow flight, according to timesleader.com.
The incident occurred at about 4:50 p.m. EDT as the race concluded. The race ended early due to the rain and lightning.
"A squall line containing frequent cloud to ground lightning moved through the area," said AccuWeather.com Climatologist Matthew Greene.
One person died, four people are being evaluated and five people have been treated and released.
AccuWeather's Ida Lively was in her parked car in section 5 when the lightning struck.
"We could feel the 'thunder' even in the car... still hit the chest like a fireworks 'salute'," Lively said. "[everyone was] dazed. It was pouring... We knew it was close... It was flaBOOOOMsh!"
