The clean-up is underway in many areas of northeast Iowa impacted by severe weather on Saturday (June 9, 2018).

High winds caused damage across the region, while heavy rainfall caused flash flooding that washed out several roads. Now, multiple rivers are on the rise. ***See Flood Warnings Below***.

According to the Iowa Department of Transportation (IDOT), U.S Highway 218/Iowa Highway 27 -- also known as the Avenue of the Saints -- is closed in both directions near Charles City due to downed power lines. Officials shut down a three-mile stretch of the four-lane divided highway between Floyd County Road B-59 and U.S. Highway 18 early Sunday morning so Mid-American Energy crews can make the needed utility repairs.

IDOT officials said the impacted segment of the Avenue could be closed for a two or three days. Traffic was being detoured using Old Highway Road and S. Grand Ave.

There were reports that six- to seven-inches of rain fell in northern Iowa late Saturday afternoon and evening. The National Weather Service said that Waterloo had 2.02 inches, which set a record for June 9 precipitation. The old mark of 1.60 inches was set in 1966.

According to Floyd County Emergency Management officials, many roads in the county were damaged or washed out by flash flooding on Saturday and that Rockford was closed to night-time inbound traffic. Authorities said vehicles were being allowed back into the city Sunday morning.

The storm caused widespread damage in Rockford, Floyd County Emergency Management officials indicated in a Facebook post. Sunday morning, they said an organized clean-up was underway as of 8 AM and authorities were asking for volunteers to cut up trees and haul away debris. They were also encouraging spectators to stay away from Rockford so that clean-up efforts wouldn't be hindered.

Further east, authorities in Delaware County were highly discouraging travel on rural roads. Officials with the Secondary Roads Dept. said many roads -- especially those generally west of a Dundee-to-Manchester line and north of U.S. Highway 20 -- have washed out areas that will need repair. They reported Sunday morning that maintenance crews were out assessing each road for damages and beginning repairs.

Heavy rainfall on Saturday and over the past few days, especially in far northern Iowa, has brought renewed flooding to the region on the 10th anniversary of the historic, record-breaking flood of 2008.
