Two to four inches of rain are expected through Friday morning, creating a high risk of flooding along the Mississippi and Rock rivers, according to the National Weather Service.

"The rain we got last week has made all river basins very sensitive to additional rainfall," meteorologist Brian Pierce said. "The ground is moist, if not saturated, and (rain) could run off into the rivers."

He said the rain could raise river levels by a few feet, depending on the location. The Rock River in Moline was holding at just below flood stage Tuesday.

The Mississippi River is expected to crest at 15.7 feet in Rock Island at 2 p.m. Sunday, according to the NWS Quad-Cities website at water.weather.gov. The level at Rock Island was 14.4 feet at 3 p.m. Tuesday.

Flood stage for the Mississippi at Rock Island is 15 feet, with 16 feet deemed as moderate flooding, according to the website.

At 15 feet, flooding affects sections of South Concord Street south of River Drive in Davenport and reaches the foundations of some homes on Enchanted Island. Businesses along the river in the south end of Davenport also are affected.

At 16 feet, water covers sidewalks in Davenport's LeClaire Park and Credit Island and parts of River Drive in Moline in the 4700 block.
