HOPKINSVILLE, Ky. (AP) — Another round of torrential rain and flash flooding was expected to hit Saturday in parts of the South and Midwest already heavily waterlogged by days of severe storms that in some cases spawned deadly tornadoes.

Round after round of heavy rains have pounded the central U.S., leading to rapidly rising waterways and prompting a series of flash flood emergencies Friday night in Missouri, Texas and Arkansas. Meanwhile, many communities were still reeling from tornadoes that destroyed entire neighborhoods and killed at least seven people earlier this week.

In Frankfort, Kentucky, floodwaters swept a 9-year-old boy away while he was walking to a school bus stop Friday morning, Gov. Andy Beshear said on social media. Officials said Gabriel Andrews’ body was found about a half-mile from where he went missing.

The downtown area of Hopkinsville, Kentucky — a city of 31,000 residents 72 miles (116 kilometers) northwest of Nashville — was submerged Friday. A dozen people were rescued from homes, and dozens of pets were moved away from rising water, a fire official said.

Tony Kirves and some friends used sandbags and a vacuum to try to hold back rising waters that covered the basement and seeped into the ground floor of his photography business in Hopkinsville. Downtown was “like a lake,” he said.

“We’re holding ground,” he said. “We’re trying to maintain and keep it out the best we can.”

Flash flood threat looms over many states

Flash flood emergencies were issued Friday night in at least seven cities in Missouri, Texas and Arkansas, according to the National Weather Service.

One was in Van Buren, Missouri, where there were at least 15 water rescues amid heavy rainfall and a rapidly rising Current River, said Justin Gibbs, weather service meteorologist. Another was in Texarkana, Texas, where the flooded streets resulted in several people having to be rescued from their vehicles, according to the city’s police department.

“If you don’t have darn good reason for being out (like one that involves a visit to the emergency room), please stay home and off the roads!!” the police department said on social media.

Heavy rains were expected to continue in parts of Missouri, Texas, Arkansas, Kentucky and elsewhere Saturday and could produce dangerous flash floods. The 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.

In Christian County, Kentucky, which includes Hopkinsville, 6 to 10 inches (15.2 to 25.4 centimeters) fell since Wednesday evening, the NWS said Friday afternoon. The rain caused the Little River to surge over its banks, and 4 to 8 inches (10.2 to 20.3 centimeters) more could fall by Sunday, it said.

Hundreds of Kentucky roads were impassable Friday because of floodwaters, downed trees or mud and rock slides, and the number of closures were likely to increase with more rain Saturday, Beshear said.

Flash flooding is particularly worrisome in rural Kentucky where water can rush off the mountains into the hollows. Less than four years ago, dozens died in flooding in the eastern part of the state.

Extreme flooding across a corridor that includes Louisville, Kentucky and Memphis — which have major cargo hubs — could also lead to shipping and supply chain delays, said Jonathan Porter, chief meteorologist at AccuWeather.

Swollen rivers and tributaries also swamped some parts in Ohio on Friday, and Gov. Mike DeWine said about 70 roads were closed. The southern half of the state was expected to see moderate flooding, which has not happened in four years, he added.

Forecasters attributed the violent weather to warm temperatures, an unstable atmosphere, strong wind shear and abundant moisture streaming from the Gulf. At least 318 tornado warnings have been issued by the NWS since this week’s outbreak began Wednesday.

The outburst comes at a time when nearly half of NWS forecast offices have 20% vacancy rates after Trump administration job cuts — twice that of just a decade ago.

Tornadoes leave a path of damage, and more could be coming

At least two reports of observed tornadoes were noted Friday evening in Missouri and Arkansas, according to the NWS.

“TAKE COVER NOW!” the weather service said on X in response to the one on the ground around the small Missouri town of Advance.

Earlier in the week, seven people were killed in the initial wave of storms that spawned powerful tornadoes on Wednesday and early Thursday in Tennessee, Missouri and Indiana.

Tennessee Gov. Bill Lee said entire neighborhoods in the hard-hit town of Selmer were “completely wiped out,” after it was hit by a tornado with winds estimated by the NWS of up to 160 mph (257 kph). Advance warning of storms likely saved lives as hundreds of people sheltered at a courthouse, the governor said.

In neighboring Arkansas, a tornado near Blytheville lofted debris at least 25,000 feet (7.6 kilometers) high, according to weather service meteorologist Chelly Amin. The state’s emergency management office reported damage in 22 counties from tornadoes, wind, hail and flash flooding.

Mississippi’s governor said at least 60 homes were damaged. And in far western Kentucky, four people were injured while taking shelter in a vehicle under a church carport, according to the emergency management office in Ballard County.
