Showers and thunderstorms, including the threat of tornadoes, are affecting this year's Daytona 500, but the race was restarted after a more than six-hour red-flag delay.
While it has not rained the entire weekend, the thunderstorms occurred at the most inopportune time for the 56th running of The Great American Race.
Officials advised fans to clear the grandstands around 3 p.m. EST Sunday as a thunderstorm capable of producing a tornado threatened the Daytona Beach area.
Additional thunderstorms followed for the remainder of the afternoon, leading to a longer delay.
The race restarted under caution at Lap 39 and resumed under Green Flag racing at Lap 47 about 8:55 p.m. EST Sunday.
The race has been shortened four times due to rain, during the years 1965, 1966, 2003 and 2009.
