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.

National Weather Service data shows at least two tornadoes formed in Iowa Friday. The pair of twisters touched down on opposite sides of the state. The first tornado appeared around 3:45 p.m. in a field a few miles northeast of Clarinda. No damage was reported, so the short-lived tornado was rated EF-Unknown.
