Fernando Alonso will again attempt to complete motorsports' Triple Crown with a return to the Indianapolis 500 in May with McLaren.

James Hinchcliffe will return to Andretti Autosport for three races during the 2020 season -- the road course race at Indy, the Indy 500 and at Texas Motor Speedway.

Other changes coming to the Indianapolis 500 this May include new rules for qualifying, a larger prize purse and updates to seating and video screens.

With rain and thunderstorms forecast through the holiday weekend, the Indianapolis Motor Speedway is encouraging fans to be prepared.
