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.

Flood warnings were in effect in several areas, including ones that were devastated by the July 4 floods. By the afternoon, the rain had eased up in some parts, and some rescuers resumed their work.

Residents south of the San Saba River in west-central Texas have been ordered to evacuate because of surging waters.

With Central Texas devastated by deadly floods, many are asking: What’s a 100-year or 1,000-year flood, and are these terms outdated?
