The storms have caused localized flooding, power outages, hail, and wind damage. Roads in parts of Des Moines are closed due to flooding, and flash flood warnings are in place for the metro area and Ames. Residents in southern Iowa may experience severe weather until midnight, with risks of hail and heavy rain. Travelers should exercise caution, especially in areas with water-covered roads. The cooler temperatures following the storms provide relief from the earlier heatwave.
