Swollen rivers are flooding towns in the US South after a prolonged deluge of rain

Cities ordered evacuations and rescue crews in inflatable boats checked on residents in Kentucky and Tennessee, while utilities shut off power and gas in a region stretching from Texas to Ohio. Floodwaters forced the closure of the historic Buffalo Trace Distillery, close to the banks of the swollen Kentucky River near downtown Frankfort, Kentucky.

Salon owner Jessica Tuggle watched Monday as murky brown water approached her Frankfort business. She and her friends had moved her salon gear — styling chairs, hair products and electronics — up the hill to a nearby taproom.

"Everybody was just, 'stop raining, stop raining,' so we could get an idea of what the worst situation would be," she said.

Officials diverted traffic and turned off utilities to businesses in Frankfort as the river crested just short of a record Monday. More than 500 state roads across Kentucky were still closed Monday morning, Gov. Andy Beshear said.

Ashley Welsh, her husband and four children — along with their pets — had to leave their Frankfort home along the river Saturday evening, abandoning a lifetime of belongings to the floodwaters.

When she checked her house's cameras Sunday morning, the water had risen to the second floor.

"My stuff was floating around in the living room. I was just heartbroken. Our life is up there," Welsh said.

Storms leaving devastating impact

Twenty-one deaths have been reported since the storms began Wednesday. A 9-year-old boy in Kentucky was caught up in floodwaters while walking to catch his school bus. A 5-year-old boy in Arkansas died after a tree fell on his family's home, police said. A 16-year-old volunteer Missouri firefighter died in a crash while seeking to rescue people caught in the storm.

Kentucky State Police said Monday they recovered the body of a McCracken County man swept away by floodwaters Sunday while trying to retrieve his boat.

Two men sitting in a golf cart, a father and son, were killed when a tree fell on them at a golf course in Columbus, Georgia, according to Muscogee County Coroner Buddy Bryan.

The National Weather Service warned that dozens of locations in multiple states were expected to reach a "major flood stage," with extensive flooding of structures, roads, bridges and other critical infrastructure possible. Though significant rains have ended in the Southern Plains and the Mississippi, Tennessee and Ohio valleys, flooding on most rivers will persist this week, with some smaller waterways receding in the next few days, according to the weather service.

The Kentucky River was cresting at Frankfort Lock at 48.27 feet (14.71 meters) on Monday morning, just shy of the record of 48.5 feet (14.8 meters) set there on Dec. 10, 1978, according to CJ Padgett, a meteorologist with the weather service's Louisville, Kentucky, office.

Beshear said more than 1,000 people had no access to water and nearly 3,000 were under boil water advisories. He said at least 20 water systems were affected.

The city of Harrodsburg about 30 miles (48 kilometers) south of Frankfort said on social media that its water system had to discontinue pumping around midnight because of flood levels on the Kentucky River. Bottled water was being handed out Monday.

John and Phyllis Sower hunkered down about a half-block from the river in their Frankfort home, which had about 4 feet (122 centimeters) of water in the cellar. While they stood on their front porch Monday, a neighbor waded over to bring them flowers.

"We are an island in the Kentucky River," Phyllis Sower said.

In northeastern Arkansas, Gov. Sarah Huckabee Sanders called the scene "absolutely heartbreaking" around the town of Hardy, which took damage to its city hall and other buildings. Sanders and local officials vowed to rebuild.

West Memphis, Arkansas, Fire Chief Barry Ealy told WREG-TV that crews in the flood-prone city have rescued more than 100 people. The city across the Mississippi River from Memphis, Tennessee, still had some flooded streets Monday.

More than 100 structures were destroyed in McNairy County, Tennessee, where a tornado tore through the town of Selmer with winds estimated up to 160 mph (257 kph), local emergency management officials said. State officials say severe weather killed five people in the county of roughly 26,100 residents.

Why so much nasty weather?

Forecasters attributed the violent weather to warm temperatures, an unstable atmosphere, strong winds and abundant moisture streaming from the Gulf.

The NWS said 5.06 inches (nearly 13 centimeters) of rain fell Saturday in Jonesboro, Arkansas — making it the wettest day ever recorded in April in the city. Memphis, Tennessee, received 14 inches (35 centimeters) of rain from Wednesday to Sunday, the NWS said.

The storms come after the Trump administration cut jobs at NWS forecast offices, leaving half of them with vacancy rates of about 20%, or double the level of a decade ago.
