Severe storms and a Tornado Warning halted the IndyCar practice at Iowa Speedway Friday, sending drivers and fans scrambling for shelter. The doubleheader weekend is still on track with clearer skies and cooler temperatures expected Saturday and Sunday after the passage of the storms.

Heavy rain caused flooding issues in Ames and rotation was observed in clouds around the Iowa Speedway in Newton as the area was under a tornado warning. All watches and warnings have expired for central Iowa, but major flooding continues in some eastern Iowa communities after heavy rain and possible tornadoes.
