NASCAR officials decided to cancel practice and qualifying Tuesday, meaning the 43-car fields for the Winston Cup and Busch Series Stacker 200 will be set by the points standings in each series.
The National Weather Service issued a tropical storm warning for areas from the northern Virginia coast to New Jersey, which includes Delaware Bay. The speedway is less than 30 miles from the bay.
Series points leader Matt Kenseth gets the pole for Sunday's race. He has led the standings for 24 straight weeks and finished in the top 10 in each of the last seven events.
Kenseth and his Ford Taurus enter the race with a gigantic 404-point lead over Dale Earnhardt Jr., who will start second in a Chevrolet Monte Carlo.
