(CNN) -- Some of the worst flooding the mid-South has seen in decades is thought to be responsible for at least 11 deaths in Tennessee, the Nashville and state emergency management offices said Sunday. Five of the deaths were in Davidson County, which encompasses Nashville, according to the Nashville mayor's Office of Emergency Management. The rains have closed interstate highways, displaced thousands from their homes, prompted evacuations of hotels and nursing homes and turned city streets and parking lots into raging rivers. Parts of the state have been drenched with up to 20 inches of rain, with more expected. iReport: Experiencing the Tennessee floods? Send photos, video
