SB Nation's Jeff Gluck is in Daytona and working hard to update the developing weather situation at Daytona International Speedway.
Totally raining. Totally a bummer. At the very least, Daytona 500 will be delayed a few hours. Rain now means it cannot start on time.— Jeff Gluck (@jeff_gluck) February 26, 2012
Gluck along with Brian Neudorff have been following the weather situation since yesterday. Neudorff in earlier update said there was probably a 70 percent chance that today's race would occur either Sunday night or on Monday.
Rain is falling in Daytona and is likely to continue throughout the rest of the evening. There is a chance that things could improve during the early evening hours which would turn the 54th running into a night race. The 500 has never been ran on a Monday but that is becoming more of a possibility.
