Flash floods in Missouri, Kentucky and Tennessee have prompted major evacuations and water rescues on Friday and Saturday, and even more rain is expected to fall this weekend.

Happening now

The latest flash flood warning with a considerable tag has been issued in Cocke County in eastern Tennessee. Water has been reported in multiple homes and water rescues are ongoing. There is water on numerous roadways and a few mudslides have also been reported.

There have been reports of 3- 5 inches of rain falling in just 3 hours.

The heaviest rainfall has been occurring across Kentucky, Missouri and Tennessee. These areas could see another 1-3 inches of rain through the weekend. That may not seem like much, but with such saturated ground, it's more than enough to cause more flooding.

Flooding overnight in Kentucky

Flash flood warnings were issued for Louisville through the overnight hours. Water rescues were reported across Louisville as cars were stuck in high standing water on roads.

In this area, over 2 inches of rainfall was reported in 6 hours. Rainfall totals have reached 5-8 inches in some areas, with isolated totals seeing even more than this.

Heavy rain also fell across western Kentucky, where a flash flood warning with a considerable tag was issued by the National Weather Service. In Salem, this rainfall caused two vehicles to be stranded in floodwaters on the highway.

Missouri state of emergency

Missouri Gov. Mike Kehoe declared a state of emergency as first responders raced to rescue people trapped by rapidly rising water in Reynolds and Iron counties. 

Oates, Missouri, in Reynolds County, saw an impressive 12.25 inches of rainfall Friday overnight into early Saturday.

The Black River exploded to an unprecedented crest of 28.7 feet, obliterating its previous record and surging far beyond major flood stage.

The sudden deluge overwhelmed rivers, flooded homes, washed over roads and inundated campgrounds that are especially busy during the summer.

Emergency responders say rescues have already taken place at three campgrounds along the Black River: Twin Rivers Landing, Riversedge and Bearcat Getaway, where a building collapsed into floodwaters. Twenty people were rescued from the collapsed building.

The flooding also threatened Camp Taum Sauk near Lesterville, a popular summer camp in the region. Over 200 children and staff were rescued by Black Hawk helicopters and taken to a nearby elementary school and reunited with their families.

Three people were also rescued from trees in Reynolds County on Friday night.

The response has grown into a massive operation involving the Missouri State Highway Patrol, State Emergency Management Agency, Division of Fire Safety, Missouri State Parks, Missouri Department of Conservation and local emergency responders. Missouri Task Force 1 has also been deployed with 50 specially trained rescue personnel, boats and specialized equipment.

The National Weather Service issued a rare Flash Flood Emergency for parts of Iron and Reynolds counties, warning that the flooding continues to be life-threatening.

"If you're camping, floating, or spending time near rivers and streams, move to higher ground and stay alert of weather conditions," Kehoe warned. "Missourians should continue to monitor local forecasts and follow the guidance of local authorities."
