Overview

Rounds of thunderstorms with heavy rain tracked over the same areas repeatedly during the evening of Tuesday, August 23rd through the early morning of Wednesday, August 24th. Rainfall accumulated between 5 to 8" across extreme northeast Iowa into southwest Wisconsin.

This led to widespread flooding and rapidly rising rivers. One elderly man was killed in rural Chickasaw Co., IA when his car was swept away by flood waters during the early morning hours (4:40 a.m.). There were numerous road closures, water rescues, and homes inundated by flood waters.

Rivers impacted included the Cedar, Upper Iowa, and Turkey in northeast Iowa. In southwest Wisconsin, the Kickapoo River had some flooding.

Turkey River @Spillville - crest of 20.25'
Turkey River @Eldorado - crest of 21.92'
Upper Iowa @Dorchester - crest of 24.27'
