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 been found dead since heavy rainfall overwhelmed the river and flowed through homes and youth camps in the early morning hours of July 4. Ninety-six of those killed were in the hardest-hit county in central Texas, Kerr County, where the toll includes at least 36 children.

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.

Multiple parts of Central Texas, including Kerr County, were shocked by flash floods Friday when the Guadalupe River and others rose rapidly.

KERRVILLE, Texas (AP) — Over the last decade, an array of Texas state and local agencies missed opportunities to fund a flood warning system intended to avert a disaster like the one that killed dozens of young campers and scores of others in Kerr County on the Fourth of July.

Flash floods last week in Texas caused the Guadalupe River to rise dramatically, reaching three stories high in just two hours.

Kerrville city employees Rosa Ledesma and Alex Benitez talk with CNN’s Pamela Brown about how they received the call about the Texas flooding and jumped into action to save people.

A Kerrville-area river authority executed a contract for a flood warning system that would have been used to help with emergency response, local officials said.
