NASCAR officials have postponed the 50th running of the Coca-Cola 600 at Lowe's Motor Speedway until Monday, as rain continued to fall.
Despite the crew's best efforts to get the track dry after a number of showers during the afternoon, the radar continued to show further rain coming into the Charlotte area, thus making it unlikely to run the 400 scheduled laps.
The race has been postponed until noon local time on Monday, although the weather forecasts show rain could persist during the day with an increasing chance of thunderstorms into the afternoon.
Teams have done all their planning for a night race with cool track temperatures, but with the new starting time for the event and a green track due to the showers, they will face setup uncertainties come Monday.
"As for the race, everyone was set up for racing at night," Penske driver Kurt Busch explained. "This will really have everyone scratching their heads, that's for sure. We were hoping to have an adjustable setup here tonight.
"Running here tomorrow will definitely put a bigger premium on the adjustability factor. I know everyone will be really loose at the start of the race because all the rubber got washed off the track.
"It'll get tighter as the race goes on and that's where the adjustability comes in."
