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."

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.

Well, it could take months for Texas families to experience some form of closure as more than 170 people remain missing, nearly a week after those deadly floodwaters rushed in the Texas Hill Country on July 4 as four months of rain fell in just two days over central Texas.

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.

Also: San Antonio mourned the victims in a Travis Park vigil; UTSA said one of its teachers died in the Guadalupe River flood; Kerrville officials said a privately owned drone collided with a helicopter conducting search and rescue operations.

Camille Santana tragically lost her life during the Fourth of July floods that swept through Central Texas. Three other members of her family remain missing.

Many Catholics in the region have been stepping up to help, converging on Notre Dame Parish in Kerrville, located in the hardest-hit community along the Guadalupe River.

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.
