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.

FEMA and the U.S. Small Business Administration, in coordination with the Texas Division of Emergency Management, are opening a Disaster Recovery Center in Kerrville on Thursday, July 10, to help homeowners, renters and business owners impacted by the flooding.

A major flood event also struck the Texas Hill Country in July of 1987 after a series of 17 thunderstorms moved slowly, in succession, over the headwaters of the Guadalupe River in Kerr County. Anywhere from 5 to 10 inches of rain fell on the flood-prone areas, now deemed “Flash Flood Alley,” according to a National Weather Service report.

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.

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.

Amid the evacuation alert in Kerrville, unverified reports began circulating online claiming that the Ingram Dam, located on the Guadalupe River, had collapsed.

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.

The recent disaster has some thinking back to a similar tragedy almost 40 years ago that occurred in the same month and nearly the same place.
