A timelapse video shows the rapid overflow of the Llano River and its subsequent flooding in central Texas on July 4, highlighting how swiftly the water level rose.

The state’s Hill Country region was hit by exceptionally heavy rain, leading to severe flash floods that claimed at least 80 lives over the weekend. The footage captures a portion of the river near Kingsland, around 100 miles northeast of the particularly affected Kerr County, swelling dramatically in just over 10 minutes.

“I record the crossing 24/7 with a security camera,” Robert Ivey informed the newsgathering website Storyful. “The river crossing, also known as ‘the slab,’ is a popular local swimming spot.”

Kingsland, located about 70 miles northwest of Austin, was among several communities impacted by Texas’ deadly flooding.

Kerr County – located farther southwest – suffered the highest reported death toll, with officials confirming at least 80 deaths by Monday morning. Many of the victims were attending an all-girls summer camp in the area, authorities said. Dozens remain unaccounted for as search and rescue efforts continue across the region.

Meteorologists say the flooding was driven by a slow-moving storm system that dumped several inches of rain in a matter of hours, overwhelming local waterways and catching many off guard despite flash flood warnings.
