Another round of storms is expected to pass through South-Central Texas on Thursday, July 16, according to the National Weather Service (NWS). It comes after emergency officials led evacuations near San Antonio as flooding surged in areas near rivers and lakes.
There is a 50% chance of showers and thunderstorms developing over the Alamo City sometime during the daylight hours, forecasters say. It could result in new rainfall amounts ranging between a tenth and a quarter of an inch.
Still, low-lying areas will be especially prone to flooding. Roughly 25 miles north, Fair Oaks Ranch had received roughly 11 inches of rain since Monday, July 13, according to KWTX News 10. Near Camp Wood, that number was around 15 inches, and by Uvalde, it was approximately 17 inches. Hondo sat at an astounding 19 inches.
After sunset, there’s a 40% chance of rain, and wind gusts could reach 20 mph.
Through 7 a.m. on Thursday, the following areas face the highest risk (Level 4 out of 4 on the NWS’s scale) of excessive rain leading to flash flooding: Uvalde, Rocksprings, Del Rio, and Eagle Pass.
The Alamo City and several of its neighbors, including Pleasanton, Boerne, Kerrville, and Fredericksburg, face a Level 3 out of 4 risk during that same time period.
After 7 a.m. on Thursday, the risk decreases slightly. Cities west of San Antonio sit at around Level 3 or 2 through 7 a.m. on Friday, July 17. The windiness will make it feel chillier than normal. The high will be around 85 degrees, while the low will be 75 degrees, per the NWS.
In a situation report issued by the NWS, meteorologists warned that locally catastrophic flash flooding is likely. Folks may notice high water on some roads this morning as heavy rain fell over the western Hill Country, southern Edwards Plateau, Rio Grande, and U.S. 90 corridor overnight.
In particular, the agency says significant river flooding (moderate to major category) could occur in the Nueces, Frio, and Medina basins.
The Edwards Plateau, Texas Hill Country, Rio Grande Plains, and the I-35 corridor remain under a Flood Watch until Thursday evening, according to the NWS website. It includes parts of San Antonio, Austin, and New Braunfels. The agency issues a Flood Watch when conditions are favorable for flooding. It indicates a possibility, not an absolute or active event.
The agency issued a Flood Warning for Devils River at Cauthorn Ranch Near Juno and Devils River at Bakers Crossing 19N of Comstock, which impacts Val Verde County. It is in effect until the morning of Saturday, July 18. A Flood Warning means flooding is imminent or already occurring.
