Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

At least 120 people have died and some 173 people remain unaccounted for statewide, nearly a week after flash floods ravaged the Texas Hill Country.

Two days before flash floods on the Guadalupe River in Texas killed dozens of campers at a Christian girls summer camp, a state inspector approved operations, noting there was a written plan for responding to natural disasters.

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."

Sources have said FEMA wasn’t authorized to launch search and rescue teams until 72 hours after flooding began.

Coast Guard rescue swimmer Scott Ruskan helped save 165 people after the Guadalupe River surged by more than 20 feet in less than two hours early Friday in Texas.

Without a modern flood warning system, emergency officials monitor four sensors along the Guadalupe River – including one that was knocked out in the flood.

Flash floods that hit central Texas devastated Hill Country during the Fourth of July holiday weekend, killing dozens of people.
