Texas flooding updates: Over 130 dead as flash flood threat increases in Texas

A moderate risk of flash flooding has been highlighted for parts of Central Texas on Sunday, according to the National Weather Service’s Weather Prediction Center.

Places recently hit hard -- like Kerrville, Texas, and Burnet, Texas -- are inside this heightened potential for flash flooding, with any heavy rain and flash flooding that occurs over or adjacent to these areas likely to flow downstream via rivers that run through or nearby these devastated areas.

Rainfall rates up to 1 to 2 inches per hour are possible, with brief, isolated spurts of rainfall rates up to 3 to 4 inches per hour, according to the National Weather Service. This has the potential to bring high-impact flash flooding and rapid river rises.

The heaviest rain is currently to the north and west of Kerrville and Burnet toward the Junction and Killeen areas, where they have already seen between 1 to 3 inches of rain and some localized areas of up to six inches of rain in the span of six hours.

All of this heavy rain dumped into the nearby rivers, like the Lampasas River, which rose more than 22 feet in two hours earlier Sunday morning.

Life-threatening flash flooding is ongoing in the Colorado Bend State Park and surrounding areas in central Texas.

The National Weather Service in San Angelo issued a flash flood emergency for the area, along with warnings for other areas.

The area includes Chappel, Bend and U.S. Highway 190 near the San Saba-Lampasas County Line.

About 6 inches to 8 inches of rain have fallen in this area, which is about 80 miles to the north-northeast of Kerrville and about 30 miles to the northwest of Burnit.

There are also "considerable" flash flood warnings in effect for the areas surrounding the flash flood emergency, including San Saba, Richland Springs, Lake Buchanan, Lampasas and Lometa.

Dozens of active duty and former Navy SEALs are assisting search and recovery efforts in Texas Hill County in the wake of the deadly flooding last week. ABC News embedded with the volunteers in an exclusive report.

More than 30 SEALs are lending their expertise in navigating difficult terrain and diving in the Guadalupe River as miles of destruction and debris line the area.

"You saw the violence of this thing," said former Navy SEAL Greg Froelick. "So, you kind of have to put that in the back of your head, like expect to potentially find the victim. But ... I think finding one, it's reassuring in the sense that now the family knows, at least they have a little bit of closure."

Froelick showed the area they first searched outside Camp Mystic, explaining their crew was using chainsaws to cut through the dense forest of flattened trees. Unfortunately, they did recover several victims.

"None of us have seen anything like this," said Froelick. "I think everyone was just taking it in and just realizing what just happened here."

The statewide death toll has climbed to 129, with 166 people still considered missing, officials said.
