UPDATE, MONDAY, 10:20 am:NASCAR President Mike Helton has just announced that the race has again been rescheduled. The green flag is set to drop at 7 pm ET.
The Daytona 500 was scheduled to run Sunday, but scattered Florida showers kept drivers off the track and the guys in the Fox commentary booth scrambling to fill several hours of live TV.
NASCAR has since rescheduled the start time for noon (Eastern) Monday. However, a look at the Daytona forecast makes the likelihood of a noon start time seem unlikely.
Although rain has disrupted the Great American Race in the past, this marks the first time in the 54-year history of the race that is has been postponed to another day.
