Rolex 24 at Daytona: Rain biggest obstacle for drivers during early morning hours of endurance race
DAYTONA BEACH, Fla. -- The report from the track at 3:18am, ET, wasn't good news: The tenth full course yellow was called for inclement weather. Rain has been persistent throughout the night, but its recent increase in intensity caused race officials to take proactive measures. Green-flag racing did not resume until 4:12am, ET.
