Deaths and flood damage in Tennessee 1:00
(CNN) -
When deadly floods rushed around her Tennessee home Saturday morning, Linda Almond Bryant started a video on Facebook Live.
"We are flooded right now," he says as the water pushes debris through a door.
"Really scary."
It was the last video that he appeared to post on his Facebook page.
The flood would kill him, according to his son.
Almond Bryant, 55, was one of at least 18 people who died in Saturday's flash floods in central Tennessee, including his hometown of Waverly, west of Nashville.
Also among those killed in Waverly were 7-month-old twins.

More than 270 houses were destroyed, some ripped from their foundations, in flooding caused by heavy rains, authorities said this week.
The 70-second video of Almond Bryant and a later account of her son, who was with her, help to piece together some of her last moments.

Son says mother was lost after water washed them into a wrecked house
In the video, a man's voice says 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 found themselves in the water.
His son, Thomas Almond, reminded CNN Tuesday that he and his mother were hanging on the side of the house for 30 minutes Saturday as the flooding surrounded it.
One storm had a name, the other didn't.
Both brought floods but had different consequences
Then a different, evicted house that was on fire approached them.
They decided to let go and the water washed them away, he told CNN.
The torrent of water took them to another vacated house, which had been leaning against a service station.
"We hit the corner of the house, and when I hit it, it dragged us both down," Almond told CNN.
"And I was probably under, I don't know, thirty to forty-five seconds." And I got out, looked around, called my mom a few times.
But I didn't see it.
... I knew I had to fight for myself. "
He said the current carried him around a bend into another building, where he climbed onto a roof and stayed there for four hours until he was rescued, but his mother failed.
Up to 15 inches of rain had fallen in the area over a six-hour period, authorities said.

Humphreys County Sheriff Chris Davis took a helicopter trip this week to inspect the destruction and burst into tears when he described what he saw.
"They've seen us get a little excited about this," Davis tearfully said 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 floods in some way, Davis said.
"There are some people who were in their houses who had water up to their knees and up to their waist, and now the water has receded," he said.
CNN's Nadia Romero, Steve Almasy, and Aya Elamroussi contributed to this report.
