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."

Torrential rain flooded creeks, streams and the Guadalupe River, where the water swelled more than 26 feet in 45 minutes.

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.

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.

With more than 170 still missing, communities must reconcile how to pick up the pieces around a waterway that remains both a wellspring and a looming menace.

As the Guadalupe River swelled from a wall of water heading downstream, sirens blared over the tiny river community of Comfort -- a last-ditch warning to get out for those who had missed cellphone alerts and firefighters going street-to-street telling people to get out.

Multiple parts of Central Texas, including Kerr County, were shocked by flash floods Friday when the Guadalupe River and others rose rapidly.
