Wider weather episode

A flash flood was caused by 3 or more inches of rain in less than an hour. Many basements were flooded and left with mud and debris. Some foundations and basement walls collapsed, mainly in Sioux City. Many roads were flooded, at one intersection to a depth of eight feet, damaging vehicles by the water and debris. The flooding brought down some trees, and damaged some of the flooded streets as water undercut them. A motorist caught in the flooding and the firefighter who rescued him were treated at a hospital for hypothermia. The flooding caused crop damage in the countryside, but the amount of crop damage was not determined.
