Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

While walking in her family's neighborhood in Kerrville, Sarah Woolsey felt the devastation in the community after the deadly Fourth of July floods destroyed homes, totaled cars and left debris all over the block.

On Water Street in the City of Kerrville, a memorial wall dedicated to the lives lost in last Friday’s devastating flood is growing.

Officials in Kerr County, where the majority of the deaths from the July 4 flash floods occurred, have yet to detail what actions they took in the early hours of the disaster.

Walston drove from his home to the Center Point Bridge on FM 480 near Highway 27, where he shot video of the river below. He recorded nearly 38 minutes of surging water as it rose over 20 feet, carrying massive cypress trees, debris and even a house.

Religion and the river are constant Kerr County touchstones. As residents lean on their faith, they grapple with their relationship to the water.

Many Catholics in the region have been stepping up to help, converging on Notre Dame Parish in Kerrville, located in the hardest-hit community along the Guadalupe River.

During an interview with Fox News Monday afternoon, Lt. Gov. Dan Patrick said that he and Gov. Greg Abbott agreed that the state should erect sirens along the Guadalupe River.
