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.

Having witnessed the images of the flood-ravaged areas of Kerrville, Patrick Johnson, founder of J-STAR Ministries, made his second supply run to the area Sunday.

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 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.

Kerrville residents who turned out in force Friday to welcome President Donald Trump said his visit brought hope and comfort — and marked an important step in the town’s long road to healing and rebuilding.
