(Davenport, IA) — The National Weather Service for the Quad Cities says Mississippi River flood waters are beginning to crest in northern parts of its territory. NWS also says earlier than anticipated crests in Dubuque are likely, and that is partially due to an extended period of light to no rainfall. The Mississippi River at Rock Island was still at major flood stage on Saturday evening, at 19.76 feet. It is expected to crest in the coming days.
