At least 13 fatalities were reported Friday as devastating floods slammed Texas' Hill Country with water rescues taking place along the Guadalupe River, officials said.

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.

Multiple parts of Central Texas, including Kerr County, were shocked by flash floods Friday when the Guadalupe River rose rapidly.
