Just over a week after deadly flash floods swept through Texas Hill Country, the region may once again face a life-threatening deluge as slow-moving thunderstorms bring heavy rain, flash flooding, and rapid river rises to parts of central Texas Sunday.

The serious threat unfolding in San Saba County is along the San Saba River, another area known to flood. Rains from this weekend — on top of the already soaked ground — were forecast to raise the river above 30 inches. The river is forecast to rise faster and higher than it did on July 4.
