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 Guadalupe River flooded on Friday, July 4, impacting cities across Kerr County including Kerrville, Hunt, Ingram, and more, killing at least 27 people . At least 27 children remain missing from Camp Mystic, an all-girls summer camp in Hunt.

Gary, DeeAnn, Jake and Megan all lost their lives. Harley is still among the missing. Both families lived in Canyon Lake but have ties to the Houston and Mont Belvieu areas. Hutch and Beth Bryan, formerly of Houston, died in the Texas Hill Country flooding.

Camp Mystic is grieving the loss of 27 campers and counselors following the catastrophic flooding in the Texas Hill Country.

Religion and the river are constant Kerr County touchstones. As residents lean on their faith, they grapple with their relationship to the water.

Fatigue and frustration are growing among rescue workers who are ending another long day of searching for those who perished in last week's Hill Country flood disaster. Some volunteers involved in the search are even resorting to on-site IV injections to get through the hottest day yet in the Guadalupe River basin,

For the third straight day, thunderstorms have posed what meteorologists call life-threatening conditions in the Hill Country, where flooding earlier this month killed at least 131 people.
