Drivers and fans: Start your engines with this weekend's race schedule at Daytona!

Keep up with the latest weather and schedule updates! Here's the most recent update: Xfinity Series race has been postponed until Monday.

UPDATE AS OF 10 am ET Sunday:

Weather has washed out the running of the 66th Daytona 500 at Daytona International Speedway on Sunday afternoon.

Now, the big race will take the green flag Monday at 4 pm ET, while the postponed Xfinity Series race will still be held at 11 a.m. ET.

Weather looks good so we should hopefully get both delayed races in on Monday.

UPDATE AS OF 5:30 pm ET Saturday:

EDITOR'S NOTE: Rain has washed out Saturday's Xfinity Series race. It has been rescheduled for Monday, Feb. 19, with a green flag start of 11 am ET. At this writing, the 66th Daytona 500 is still scheduled for Sunday, Feb. 18, at 2:30 pm ET, although weather remains a significant concern with most forecasts calling for the chances of rain at 90 percent to 100 percent. We will keep you notified if there are further schedule changes or updates.

UPDATE AS OF 5:45 pm ET Friday:

EDITOR'S NOTE: Due to the threat of rain most of the weekend, the ARCA race originally scheduled for Saturday has been moved up to 10:30 pm ET Friday night. The race will start out being televised on FS2 and upon the conclusion of the basketball game that is being televised on FS1, the remainder of the ARCA telecast will be aired on FS1.

Also, as an aside, both Saturday's Xfinity Series race and Sunday's Daytona 500 are in jeopardy of being washed out due to the weekend forecast, with estimates of 90% or greater chance of rain throughout both days and evenings. Contingency plans are reportedly underway to hold both races on Monday, if necessary -- and obviously, if the weather cooperates. If not, both races potentially could be delayed to Tuesday, when the forecast appears to be much more amenable.
