Flash Flooding Forces I-90 Closure and Floods Homes in Southern Minnesota

Storms that dumped several inches of rain in a few hours produced sudden flash floods, prompting emergency rescues and the start of countywide damage assessments.

Overview

  • The storms, which dropped roughly 3 to 7 inches in parts of Mower County, produced rapid flash flooding late Wednesday that left streets submerged and water over a stretch of Interstate 90.
  • First responders carried out multiple rescues in Adams, LeRoy and Austin with all people and pets reported safe and no serious injuries recorded.
  • After waters receded, MnDOT and Austin police reopened the affected I-90 lanes on Thursday morning while flood warnings for the Cedar River and local creeks remained in effect.
  • Beaver Creek Valley State Park remains closed as DNR crews remove debris and inspect roads and bridges for damage before reopening.
  • Officials are conducting damage assessments over the next days, urging residents to file county damage reports, and mobilizing relief from local groups as sewer and stormwater systems show strain and property losses are tallied.
