Flash floods in Missouri, Kentucky and Tennessee have killed at least one person, destroyed buildings and prompted major evacuations and water rescues on Friday and Saturday.

Even more rain is expected to fall on Sunday, potentially causing more flooding issues.

Happening now

Since Friday, the severe weather has impacted a wide region stretching from the Ozark Mountains in southern Missouri eastward into much of the Ohio and Tennessee river valleys.

The storms could bring damaging winds, heavy rainfall and scattered flash flooding to the multistate region, with some places seeing impacts into Sunday. In eastern Tennessee, flooding closed some roads and downed power lines, and authorities from Kentucky to West Virginia told people to be ready to seek higher ground.

Missouri’s Emergency Management Agency warned that while the storms move south and out of the state, further thunderstorms could still bring additional flash flooding, especially in areas that have already received 6-12 inches of rain.

Flood watches have been extended through Sunday evening for portions of Tennessee, Kentucky, West Virginia and Virginia. 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.

Missouri woman swept away in floodwaters

The body of Faith Gregory, who went missing in Crawford County after her home was swept away from its foundation, was found by volunteers late Saturday morning. Her body was discovered about 1.8 miles downstream from her residence in Huzzah Creek, according to the county sheriff's office.

“This is not the outcome that any of us were hoping for. Our thoughts and prayers are with Faith’s family, friends, and all those affected by this tragic loss,” the sheriff's office said in a statement.

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.

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.

Summer campers rescued in Missouri

Missouri Gov. Mike Kehoe declared a state of emergency on Friday 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 took place at several campgrounds along the Black River, including 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.

"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."
