Hannibal Emergency Management Director John Hark says the flood gates on Hill Street and Center Street will be put in place starting around 8 a.m. Hark says this is because the Mississippi River is currently expected to crest at 21.1 feet by next Wednesday. Hark says this should be considered a precaution because of heavy rain expected in the next 48 hours.
