Plans to develop a flood monitoring system in the Texas county hit hardest by deadly floods were scheduled to begin only a few weeks later.

A retired nurse, her son and a family friend say they were lucky to survive last week's flash floods in Texas that killed more than 100 people, including many summer campers.

New satellite images released from Maxar Technologies show the destruction of the flash floods that have resulted in the deaths of more than 100 people over the July 4 weekend.Local authorities estimate around 160 people are still missing as Thursday marks the seventh day of the search for victims.

Rain rushing to the Guadalupe took it from a depth of less than 8 feet to 37.5 feet, a deluge with as much volume as an aircraft carrier over five minutes.

Walston drove from his home to the Center Point Bridge on FM 480 near Highway 27, where he shot video of the river below. He recorded nearly 38 minutes of surging water as it rose over 20 feet, carrying massive cypress trees, debris and even a house.

The flooding has transformed Hunt into what observers are describing as a war zone, with the town bustling with search crews, first responders, and volunteers working around the clock. DPS checkpoints have been established to keep out those who don't live in the area as recovery efforts continue.

The Guadalupe River has risen to catastrophic levels in the same area three times in the past century, impacting camps and campers each time.

It took just 90 minutes for the river to rise more than 30 feet. A look at the historic flood levels now etched into Central Texas history.
