The Sprint Cup Series race was scheduled to go green at 1:12 p.m. Eastern at Pocono Raceway but the area is currently receiving heavy rain and strong thunderstorms.
It takes around two hours to dry the track once it stops raining. Even it stopped shortly the race would likely not begin until around 3 p.m.
However, weather radar shows additional systems arriving later this afternoon. The track has no lights so the race would likely need to start by 5 p.m. to be held today.
Juan Pablo Montoya will start the race from the pole.
