HOPKINSVILLE, Kentucky (AP) — Another round of torrential rain and flash flooding was coming Saturday for parts of the South and Midwest already heavily waterlogged by days of severe storms that also spawned some deadly tornadoes.

Round after round of heavy rains have pounded the central U.S., rapidly swelling waterways and prompting a series of flash flood emergencies in Missouri, Texas and Arkansas. The National Weather Service said 45 river locations in multiple states were expected to reach major flood stage, with extensive flooding of structures, roads and other critical infrastructure possible.
