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

At least 120 people have died and some 173 people remain unaccounted for statewide, nearly a week after flash floods ravaged the Texas Hill Country.

As families and search crews sift through debris, mangled trees and toppled vehicles in Kerr County after the catastrophic Fourth of July flooding, authorities are facing growing questions about whether enough warnings were issued.

Since 2016, the topic of a "flood warning system" for Kerr County has come up at 20 different county commissioners' meetings, according to minutes. The idea for a system was first introduced by Kerr County Commissioner Thomas Moser and Emergency Management Coordinator Dub Thomas in March 2016.

Rainfall near the areas affected by the devastating Guadalupe River flood has caused a flash flood advisory to be issued.

When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.

Federal forecasters issued their first flood warning at 1:14 a.m. on July 4. Local officials haven’t shed light on when they saw the warnings or whether they saw them in time to take action.

A "Basic Plan" for emergency response for three Texas counties labeled flash flooding as having a "major" impact on public safety, according to a page on a city website.
