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

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 search and rescue efforts are intensifying for more than 160 people who remain missing days after flash floods killed more than 100 people in central Texas. New satellite imagery collected on July 8 shows the aftermath of the devastating flood along the Guadalupe River that swept through the area near Hunt and Kerrville, Texas.

Over the last decade, an array of local and state agencies have missed opportunities to fund a flood warning system intended to avert the type of disaster that swept away dozens of youth campers and others in Kerr County,

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.

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.

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.
