Various rainfall amounts ranging anywhere from one-to-five inches fell across the region. The Waterloo Regional Airport recorded 2.07", but 3" totals were reported in other parts of the city.
Widespread flash flooding was reported in Black Hawk, Buchanan and Delaware counties. Downpours caused street flooding in both Independence and Manchester, and several homes in both cities had basement flooding.

Iowa Highway 13 (Main Street) in Manchester was closed overnight and was still listed as closed on the Iowa Department of Transportation's website, as of 10 AM Tuesday.
