Kerr County, Texas and national search and rescue operations will continue Monday around the Guadalupe River, where families wait for news of their loved ones.

In the early hours of July 4, the only sound many of the vacationers along the banks of the Guadalupe River would have heard was pounding rain and thunder. They didn’t get any official warning of the rapidly rising waters that ultimately proved deadly to dozens of people swept away in central Texas flash floods.

The number of people known to be missing in Central Texas flooding last week has risen dramatically to 173 people, Governor Greg Abbott revealed Tuesday.
