This part of Texas Hill Country is known for flash floods. Why were so many people caught off guard when the river turned violent?

The Texas Hill Country has been notorious for flash floods caused by the Guadalupe River. Here's why the area is called "Flash Flood Alley."

People awoke from water rushing around them during the early morning hours of July 4, all along the Guadalupe River in the Texas Hill Country. Residents were seemingly caught off guard, but warnings had been issued days and hours before floodwaters began carrying away homes,

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.

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.

The organizations working together to help the flood victims said that 'no additional in-kind donations (clothing, food, supplies) are needed in Kerrville.' They said the best way to help is with monetary donations.

Volunteers and professionals from around the country and Mexico are still searching the challenging terrain for victims of the Texas flood.

The storied Guadalupe River meanders through this Texas Hill Country town and into the unincorporated parts of Kerr County like a vein.

Officials in Texas are facing questions about whether they did enough to get people out of harm's way before a flash flood swept down the Guadalupe River and killed at least 120 people, including more than two dozen children and counselors at an all-girls Christian camp.

In the Texas Hill Country, as the search for loved ones lost to the Guadalupe River ends, the search for their belongings begins.
