At least 22 people were killed, and rescue crews searched desperately Sunday amid shattered homes and tangled debris for dozens of people still missing after record-breaking rain sent floodwaters surging through Middle Tennessee.
Saturday's flooding in rural areas took out roads, cellphone towers and telephone lines, leaving families uncertain about whether their loved ones survived the unprecedented deluge. Emergency workers were searching door to door, said Kristi Brown, a coordinator for the health and safety supervisor with Humphreys County Schools.
Many of the missing live in the neighborhoods where the water rose the fastest, Humphreys County Sheriff Chris Davis said. Their names were on a board in the county's emergency center and listed on a city department's Facebook page.
The dead included twin toddlers who were swept from their father's arms, according to surviving family members. The sheriff of the county of about 18,000 people some 96 kilometers (60 miles) west of Nashville said he lost one of his best friends.
Up to 43 centimeters (17 inches) of rain fell in Humphreys County in less than 24 hours Saturday, appearing to shatter the Tennessee record for one-day rainfall by more than 8 centimeters (3 inches), the National Weather Service said.
Tennessee Gov. Bill Lee toured the area, stopping on Main Street in Waverly where some homes were washed off their foundations and people were sifting though their water-logged possessions.
Shirley Foster cried as the governor walked up. She said she just learned a friend from her church was dead.
"I thought I was over the shock of all this. I'm just tore up over my friend. My house is nothing, but my friend is gone," Foster told the governor.
The hardest-hit areas saw twice the rain that area of Middle Tennessee had in the previous worst-case scenario for flooding, meteorologists said. Lines of storms moved over the area for hours, wringing out a record amount of moisture — a scenario scientists have warned may be more common because of climate change.
The downpours rapidly turned the creeks that run behind backyards and through downtown Waverly into raging rapids. Business owner Kansas Klein stood on a bridge Saturday in the town of 4,500 people and saw two girls who were holding on to a puppy and clinging to a wooden board sweep past, the current too fast for anyone to grab them.
He isn't sure what happened to them. Klein heard that a girl and a puppy had been rescued downstream, and that another girl was also saved, but he wasn't sure it was them.
By Sunday, the floodwaters were gone, leaving behind debris from wrecked cars, demolished businesses and homes and a chaotic, tangled mix of the things inside.
"It was amazing how quick it came and how quick it left," Klein said.
The Humphreys County Sheriff Office Facebook page filled with people looking for missing friends and family. GoFundMe pages were made asking for help for funeral expenses for the dead, including 7-month-old twins yanked from their father's arms as they tried to escape.
Not far from the bridge, Klein told The Associated Press by phone that dozens of buildings in a low-income housing area known as Brookside appeared to have borne the brunt of the flash flood from Trent Creek.
"It was devastating; buildings were knocked down, half of them were destroyed," Klein said. "People were pulling out bodies of people who had drowned and didn't make it out."
At the Cash Saver grocery in in Waverly, employees stood on desks, registers and a flower rack as the waters from the creek that's usually 400 feet (120 meters) from the store rushed in after devastating the low income housing next door. At one point, they tried to break through the celling into the attic and couldn't, store co-owner David Hensley said.
The flood waters stopped rising as fast just as the situation was getting dire and a rescue boat came by. "We told him that if there's somebody else out there you can get, go get them, we think we're OK," Hensley said.
Just to the east of Waverly, the town of McEwen received 43.2 centimeters (17.02 inches) of rain Saturday, smashing the state's 24-hour record of 34.5 centimeters (13.6 inches) from 1982, according to the National Weather Service in Nashville, though Saturday's numbers would have to be confirmed.
A flash flood watch was issued for the area before the rain started, with forecasters saying 10 to 15 centimeters (4 to 6 inches) of rain was possible. The worst storm recorded in this area of Middle Tennessee dropped only 23 centimeters (9 inches) of rain, said Krissy Hurley, a weather service meteorologist in Nashville.
"Forecasting almost a record is something we don't do very often," Hurley said. "Double the amount we've ever seen was almost unfathomable."
