Heavy Rain & Flooding Locally 18 Jun 14

A flash flood warning was issued for the Brown County area overnight as another round of thunderstorms dumped a few inches of rain on southern Minnesota. New Ulm received over two-inches of rain late Tuesday and early this (WED) morning, but some locations saw over twice that amount. Several spots around the area saw some hail as well. Runoff from the excessive rain is causing flash flooding in some areas also, and the Cottonwood River has quickly exceeded flood stage and continues to rise rapidly. Flood warnings remain in effect for the Redwood and Minnesota Rivers and numerous streams and tributaries. There is also a flood warning for Blue Earth, northeastern Brown, northern Waseca, southern Le Sueur, and southern Nicollet Counties until 7 o’clock tonight.

 

Flooding in and around Mankato has closed some city streets and area highways. Around seven inches of rain late Tuesday and early Wednesday overwhelmed the city’s storm sewer system, and about a dozen streets, including Riverfront Drive, were closed due to flooding. Highway 169 southbound between St. Peter and Mankato was closed overnight because of flooding as well, and Highway 66 near Skyline south of Mankato is closed because of a mudslide. Flood warnings are in effect throughout the day today (WED) for numerous area rivers and streams after the heavy rain overnight, and even more rain is possible tonight.
