IndyCar Series drivers, fans and crew members had to wait out a tornado warning on Saturday evening at Kansas Speedway shortly after the postponement of a NASCAR Camping World Truck Series race.

Civil-defense sirens sounded at the track around 7pm local time as a tornado was spotted near Linwood, Kansas, a few miles south-west of Kansas Speedway. Crew members gathered in the track's media center and watched live television reports of the tornado, including video of the tornado on the ground.

The tornado eventually dissipated and the all-clear was sounded. Damage was reported to farm structures west of the speedway, but no injuries or damage was reported at the venue.

Given that Kansas Speedway does not have lights, Truck Series race officials were forced to abandon hopes of restarting the race on Saturday. The race will resume on Monday at 11am ET where it left off, with Mike Skinner out front followed by Brian Ickler, Matt Crafton, Ron Hornaday and Brian Scott.

Local weather forecasts give a 50 percent chance of rain and thunderstorms tomorrow, which could wreak havoc with the IndyCar Series race.

The IndyCar Series race remains scheduled for 4pm local time today, but forecasts predict heavy rain and strong storms throughout the day.
