Plans to develop a flood monitoring system in the Texas county hit hardest by deadly floods were scheduled to begin only a few weeks later.

The early warnings and alerts from the National Weather Service didn’t indicate a catastrophic flood was on its way.

More harrowing stories of survival are being told in the wake of historic flash flooding in central Texas that claimed at least 120 lives, including dozens of children who were at Camp Mystic, a historic summer camp nestled along the Guadalupe River.

A week after catastrophic floods in Central Texas, key questions remain unanswered about how state and local officials prepared for and responded to the disaster.

"It’s hard to believe the devastation," Trump said. "Trees that are 100 years old just ripped out of the ground. I've never seen anything like this, and I've seen a lot of bad ones."

Camille Santana tragically lost her life during the Fourth of July floods that swept through Central Texas. Three other members of her family remain missing.

Heavy rains in Texas Hill Country alleviated drought, but Medina County still faces exceptionally dry conditions.

Texas hydrologists working with the National Weather Service say they recognized the conditions last Thursday that could lead to catastrophic flooding on the Guadalupe River. And they say, based on past events, this kind of outcome was a known risk.

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.

As rescue efforts end, volunteers and retired responders reflect on the toll — and the hope — of bringing closure to families.
