Flood warnings were in effect across a wide swath of the central and southern US, from Wisconsin, Illinois and Ohio to Texas and Louisiana. In Michigan, states of emergency were declared in the Lansing area as officials recommended the evacuations of several neighborhoods. City officials said anyone living in the possible flood areas should temporarily leave their home by midday Thursday. Flooding also hit nearby Michigan State University, where some roads, parking lots and athletic fields were covered by water from the Red Cedar River that runs through its East Lansing campus. Classes in several buildings have been relocated and the school put up sand-filled barriers in an attempt to curb flooding.
