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.

Travel is not recommended in Delaware County. According to local Emergency Management officials, flash flooding overtook several roads there and crews are working to determine the extent of damage. 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.
