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.

Before hundreds of first responders and volunteers from around the country came to help, it was the local residents of Texas Hill Country who faced down a deadly wall of water along the Gaudalope River and witnessed terrifying scenes.

Sunday is a day of prayer across Texas. But as many filed into churches, first responders and volunteers filed into Kerr County, holding out up in their search and rescue efforts.

Of all the counties affected, Kerr County suffered the greatest losses as a deadly wall of water roared down the Guadalupe River in the early morning hours of July 4. Wednesday evening, the City of Kerrville came together in a vigil at Antler Stadium to pray for the victims and those still missing after the flood.

Just days after floodwaters raged through the Guadalupe, parts of the riverbed lay dry – and the Texas Hill Country community must now face where it goes from here.

Hill Country residents and volunteers on Tuesday continued picking up the pieces that the deadly waterway left behind days earlier.

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

The most powerful thing that I can do, is come up here and intercede with prayer for these families, that are hurting beyond what anyone can ever imagine."
