2024 Indy 500 rain plan

Reporter Nathan Brown spoke with Indianapolis Motor Speedway president Doug Boles early Sunday:

Though fans may be familiar with the typical 8-mile radius rule, where lightning within that can temporarily postpone or cancel youth sporting events, IMS says it will make calls to clear the grandstands much quicker on Sunday.

Boles said the track will have weather radars on various video screens around the property so that fans can monitor where the storm is tracking and act in ways that make them most comfortable.

"As we start seeing this storm develop, we'll start thinking about asking folks to leave the grandstands much, much earlier than an 8-mile radius, so they can implement their own safety plan," Boles said. "We've got another 120 minutes as we see how this storm develops, and then we'll make another decision on what the right thing to do is to keep our customers safe."

IMS will alert fans on weather and venue updates through its public address system and on its video boards. Fans can also text Indy500 to 67283 to have alerts sent directly to their phones.
