More rain is on the way in South Central Texas, potentially exacerbating flood conditions in an area where surging waters killed at least four people last week.

The National Weather Service warned that thunderstorms would sweep across the region overnight Sunday with continuing rain at least through Tuesday, issuing a flash flood watch for 15 counties that remains in effect through Monday evening.

“The region remains near saturated from heavy rainfall over the past month,” the agency wrote in the advisory. “Additional heavy rainfall (Monday night) and (Tuesday) could result in quicker than normal runoff leading to flash flooding.”

The affected area spans from western border counties north to Llano and Blanco counties, including the outskirts of Bexar. The region is expected to receive between one and three inches of rain, with some areas getting as much as six inches.

The continued wet weather comes as search crews in Junction found a third body Saturday night from the Llano River flood that engulfed an RV park there last week. On Friday, a 20-year-old man was swept away and killed by floodwaters of the Sabinal River.

Sunday night’s storms could carry the potential for damaging wind gusts and hail in isolated areas, the agency said. The strongest risk for those conditions is near Del Rio and Uvalde counties, according to weather service meteorologist Cory Van Pelt.

“Showers and thunderstorms will be capable of producing pockets of locally heavy rainfall along with strong gusty winds and hail,” forecasters wrote.

Van Pelt said the storms will come from the west and move east toward the Interstate 35 corridor ahead of a cold front Monday that will bring temperatures in the 40s and 50s this week.

The rain is expected to continue throughout the week. Van Pelt said the highest chances for rain are Monday and Tuesday.

Agency meteorologist Melissa Huffman said Bexar County will likely miss the worst of the rain, but that doesn’t mean San Antonians won’t notice a change.

“It’s going to get dramatically colder and it’s going to get windy,” Huffman said. “So that’s going to be the big impact that most people see.”
