Click above for the very latest from the National Weather Service.

Iowa City has announced they're closing the two northbound lanes of North Dubuque Street this afternoon (weather permitting) or Tuesday morning to allow installation of flood barriers around the University of Iowa’s Mayflower Residence Hall.  Members of the campus community and visitors are urged to find alternate routes until further notice.

The precautionary move is in response to recent and forecast heavy rainfall, which threatens to raise the water in the Coralville Reservoir and Iowa River to flood levels over the next few weeks.

Also, beginning today, the Corps will gradually increase the outflow on the Iowa River from a current rate of 7,000 cubic feet per second (CFS) to an anticipated level of 10,000 CFS on July 1st. This outflow of 10,000 CFS will remain in effect until further notice.  This is a precautionary move due to the heavy rain.

At the 10,000 CFS outflow level, Iowa City City Park and some low-lying areas are affected throughout Johnson County.  At 11,500 CFS one or more lanes on Dubuque Street near Mayflower Dorm start to be impacted.

In Cedar Rapids, traffic continues to be detoured off 1st Ave East at Cottage Grove where a power pole came down and landed on the back of a car.

Stop lights continue to be out on Mt. Vernon Road from Highway 13 to Memorial Drive.

C Avenue, between Boyson & County Home Road there are trees & power lines down on the roadway and only one lane is open in that area.

Memorial Drive SE & Spruce Ave SE is closed due to a down tree with power lines in it. The road is closed until further notice, access to Cedar Valley – Rompot area and Prairie Fisher Park is via 44^th Street to Otis Road, Otis Road to Cedar Valley area.
