DAYTONA BEACH, Fla. -- Rain is threatening to delay the start of the Daytona 500.
Intermittent showers were expected to move across Daytona International Speedway a few hours before the start of the NASCAR race, which could potentially delay the green flag. It takes about two hours to completely dry the 2½-mile superspeedway after a rainstorm.
NASCAR officials, though, were hopeful the season-opening race would be completed Sunday -- even if the entire event had to take place under the lights and in prime time.
Local forecasts called for a 70 percent chance of rain and scattered showers all afternoon and throughout the evening.
