Volunteers who are still sifting through the debris from Texas’ devastating flooding on July 4 are now being evacuated due to the threat of more heavy rain.

“MOVE TO HIGHER GROUND,” warned Kerr County officials in an urgent notice on Monday, advising that the area, already grappling with the destruction from the last two weeks, could face another round of flooding due to incoming rainfall.

A flood watch is in place for Kerrville and the surrounding regions, the hardest-hit areas from the July 4 incident that resulted in at least 130 fatalities. This warning will remain in effect until 7 a.m. on Tuesday.

“Most rainfall totals should be in the 1 to 3 inch range, but an isolated total to 6 inches cannot be ruled out,” Kerrville officials cautioned.

“Rivers and streams remain elevated and will be capable of rising rapidly with any new downpours,” they added.

Texas already saw heavy rainfall over the weekend and flash floods along the San Saba River this time, while Kerrville saw upward of 4 inches of rain in a matter of hours on Sunday.

The rainfall delayed search-and-rescue efforts in some places along the Guadalupe River, where the worst flooding was concentrated on July 4. About 170 people remain missing.
