Rain has delayed the scheduled start of Sunday's Monster Energy Cup race at Atlanta Motor Speedway.

The forecast calls for more rain through the day, but officials are hoping for a window to salvage plans for racing on Sunday.

If the race is postponed, officials could look at Monday or Tuesday as options. NASCAR crews must move equipment to Las Vegas for next week's event.

On Saturday, officials pushed back the start by one hour, to 1 p.m. ET. That didn't help, as rain began Sunday morning.

Kyle Busch won the pole for the race, edging Ryan Newman.
