Torrential overnight storms dumped as much as eight inches of rain across the Texas Hill Country and Concho Valley early Sunday, prompting a series of flash-flood warnings. Radar estimates showed rain falling at up to two inches an hour on ground that was already saturated from previous storms. The National Weather Service upgraded warnings to a flash-flood emergency for eastern San Saba County, including Colorado Bend State Park, after gauges showed the Colorado River at Bend rising 12 feet around 3 a.m. CDT. In nearby Lampasas County, the Lampasas River at Kempner surged from two to 29 feet in a matter of hours and later reached a 32-foot rise, while additional gauges reported six to eight inches of rain. Flash-flood warnings remain in effect for Kerr, Lampasas, Burnet, Llano, Mason and surrounding counties, and a Flood Watch covers much of central Texas through 7 p.m. Forecasters say another five to ten inches of rain could fall as storms drift toward the I-35 corridor, raising the prospect of further river flooding and road closures. The new deluge strikes a region still reeling from the July 4 catastrophe in Kerr County, when the Guadalupe River climbed more than 25 feet in under an hour after a similar cloudburst. State officials put the death toll from that earlier flood at at least 82, with more than 40 people still unaccounted for. Emergency crews say the fresh round of heavy rain is complicating recovery work and heightening risks for communities along central Texas rivers.
