Emergency crews have suspended their search for victims of catastrophic flooding in central Texas amid new warnings that additional rain will again cause waterways to surge.

Over 120 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

The region of Texas that suffered tremendous loss last week because of heavy rain and flooding is once again in danger of taking in more water. On Sunday morning, the National Weather Service issued a flash flood warning for the epicenter of the catastrophic Independence Day flooding event.

Residents living south of the San Saba River in San Saba County have been ordered to evacuate due to river surging.

More than two dozen Mexican rescue volunteers and firefighters have been looking for victims and clearing debris along the Guadalupe River. Others were left waiting for visas and humanitarian permits to cross the border.

A National Weather Service advisory warned of another 2-4 inches of rain falling in the region − and isolated areas could see 9-12 inches.

A stretch of chain-link fence along the Guadalupe River in the Texas town of Kerrville has become a focal point for the community's grief.

Searches were suspended and a new flash flood warning was issued in Kerrville and Kerr County, Texas, on July 13 in the wake of the flooding that struck the area last week on July 4. The warning was downgraded to a flood watch hours later.
