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

Over 35,000 signed a petition urging Kerr County to install flood warning sirens after flash flooding killed at least 100 people on July 4.

Lt. Gov. Dan Patrick told CBS News Monday that the state of Texas could pay for storm sirens along the Guadalupe River.

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.

TEGNA Texas created a new charitable fund raising money to support people impacted by devastating floods in Central Texas.

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.
