The weekend's signature race, Grant Park 220, also has a time change. The race will start at 16:05 CST.
According to NASCAR earlier this week, racing will continue in the rain with car adaptations including the addition of rain tires and windshield wipers.
Fans are not allowed to bring umbrellas into the race viewing area.
The Loop 121 race was being led by Cole Custer when a red flag was raised in the area at around 17:05 on lap 26 of 55.
“I'm honestly surprised we didn't damage more cars.” Custer notified NBC during the delay. “Hats to the field so far.”
