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

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.

Unfounded rumors linking an extreme weather event to human attempts at weather modification are again spreading on social media. It is not plausible that available weather modification techniques caused or influenced the July 4 flash flooding along the Guadalupe River in Texas.

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.

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.

The Guadalupe River flooded early on Friday, July 4, as heavy rains prompted evacuations in the area. Emergency responders are frantically searching for several residents, and children from nearby summer camps are missing.

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.

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.
