Overview
|
Strong to severe storms developed across parts of southeast Minnesota into western Wisconsin during the evening of July 18th, and continued into the morning hours of July 19th. The slow moving storms produced sporadic damage, at least 1 tornado, and torrential rain. Flash flooding was probably the biggest impact from the storms, with 4 to 6 inches of rain falling across a relatively narrow axis. This led to mudslides, damaged roads, and rapid rises on area rivers and creeks. |
