Several rounds of thunderstorms developed across western and southern Minnesota during the late evening and early morning hours of Thursday, June 19th, and moved eastward through the mid morning hours. Although some of the thunderstorms did produced wind damage near Wintrop, most of the damage was associated with extreme rainfall rates, where flash flooding caused mud slides, road closures, and inundated communities.
As the thunderstorms developed near Granite Falls prior to midnight, and west of Redwood Falls, heavy rainfall caused flooded basements, one of which caused a basement wall in Belview to collapsed.
There were three rounds of thunderstorms that occurred from south central to east central Minnesota from midnight, through 9 am Thursday morning. Each round of thunderstorms produced one to two inches of rainfall, and by the time the third round moved across the same areas, nearly 4 to 6 inches fell, and produced widespread areas of flooding, with some flash flooding.
