A timelapse video has emerged depicting floodwater during the Guadalupe River flash flood in Texas surge more than 30 feet in a mere 45 minutes.
The deadly floods, which first began on Friday when the river burst its banks, have seen more than 80 fatalities, with 27 children attending an all-girls summer camp among those dead.
Casualties have been reported across six Texas counties, namely Kerr County, Travis County, Burnet County, Williamson County, Kendall County, and Tom Green County.
Rescue teams are still searching for victims and to find those unaccounted for. Police continue to collect DNA from families to identify those who have died.
In the footage, torrents of water gush down the valley, causing the water to rise at an alarming rate from 5pm to 6pm local time on Friday.
Locals in the background find themselves trapped behind the swelling water.
The waters rise over an entire road before the trees and bushes are submerged entirely.
Evacuations have been announced, with more flooding expected due to incoming rain in the course of the next few days. As it stands, estimates have suggested that around four months of rain has fallen in just a number of days.
US President Donald Trump signed a major disaster declaration on Sunday for Kerr County, which grants the area access to financial support and manpower.
He called the flash flooding in Texas "absolutely horrible" and vowed to ensure first responders "immediately have the resources they need".
Former President Barack Obama called the disaster “heartbreaking” in a statement shared on social media on Sunday.
“The flash flooding in Central Texas is absolutely heartbreaking. Michelle and I are praying for everyone who has lost a loved one or is waiting for news — especially the parents. And we’re grateful to the first responders and rescue teams working around the clock to help,” the statement read.
Flash flooding is not unheard of the Kerrville area, however, due to climate change and added moisture in the air, flash floods such as this one are likely to become more frequent.
