Woman livestreamed flooding in Tennessee shortly before it took her life

(CNN) -- As deadly flooding rushed around her Tennessee home Saturday morning, Linda Almond Bryant started a video on Facebook Live.

"We're inundated right now," she says as water pushes debris out a door. "Really scary."

It was the last video that she appeared to post on her Facebook page. The flood would take her life, according to her son.

Almond Bryant, 55, was one of at least 18 people killed in Saturday's flash flooding in central Tennessee, including her town of Waverly, west of Nashville. Also among the dead at Waverly were 7-month-old twins.

More than 270 houses were destroyed, some ripped off their foundations, in flooding from heavy rains, authorities said this week.

The 70-second video of Almond Bryant and a later account by her son, who was with her, help piece together some of her last moments.

Son says her mother went missing after floodwaters swept them into a wrecked house

In the video, a man's voice says that he thinks something just hit the house.

"This is scary," he says, and about 10 seconds later he exclaims, "Oh my God. Oh my God."

She and her son finally met in the water.

Her son, Thomas Almond, recalled to CNN Tuesday that he and his mother were hanging from the side of the house for 30 minutes Saturday as floodwaters encircled it.

Then a different, vacated house that was on fire came up to them. They decided to let go and the water swept them away, she told CNN.

The torrent of water carried them to another evicted house, which had been propped up against a gas station.

"We hit the corner of the house, and when I hit it, it dragged both of us down," Almond told CNN. "And I was probably under, I don't know, thirty to forty-five seconds." And I went out, looked around, yelled for my mom a couple of times. But I didn't see her. ... I knew she had to fight for myself."

He said the current took him around a curve to another building, where he climbed onto a roof and stayed there for four hours until he was rescued, but his mother couldn't.

Up to 15 inches of rain had fallen in the area over a six-hour period, officials said.

Humphreys County Sheriff Chris Davis took a helicopter ride this week to survey the destruction and burst into tears as he described what he saw.

"You've seen us get a little emotional about this," Davis said through tears Tuesday. "You have to remember: These are people we know. These are the families of people we know. These are people we grew up with. These are people from our little county. And they are very close to us."

Hundreds of homes were affected by the flooding in some way, Davis said.

"There are some people who were in their houses that were knee-deep and waist-deep in water, and now the water has receded," he said.
