Texas flash flood wasn't the only deadly event in the Hill Country. Here's what happened 38 years ago along the Guadalupe River.

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."

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.

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.

New flood warnings have been issued along the Guadalupe River in Texas less than two weeks after flooding killed more than 100 people.

Rainfall amounts of 1-2 inches and isolated amounts of 3-5 inches are possible, the National Weather Service said.

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.

This map shows where camps along the Guadalupe River were impacted by the July 4 flood. Meteorologists Pat Cavlin and Kim Castro detail how it all happened.

In the early days of July, pieces of weather systems were converging to create a disaster over Texas Hill Country that would transform the Guadalupe River into a monster raging out of its banks in the pre-dawn hours of July 4, claiming the lives of more than 129 people. At least 160 are still missing.

In what experts call "Flash Flood Alley," the terrain reacts quickly to rainfall steep slopes, rocky ground, and narrow riverbeds leave little time for warning.

A spokesman for Camp Mystic, the Texas enclave devastated by a July 4 flash flood, is raising concerns about communication failures during the disaster.
