Dispatch audio has surfaced from the critical hours before a deadly flood hit its height in Kerr County, helping piece together the timeframe local officials have yet to provide amid public

Kerr County applied for federal grants to build a warning system to protect residents from flash floods. Under the Trump administration, that kind of funding is drying up.

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.

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.

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.

More than 100 people have died across Texas from the floods, with Kerr County taking the heaviest blow. Nonprofits, restaurants and prominent business from H-E-B to the Salvation Army to P. Terry's are all taking efforts to raise funds or provide supplies to the impacted communities. A full list of places accepting donations can be found here.

At a Wednesday morning press conference, Kerr County Sheriff Larry Leitha declined to answer a question about delayed emergency alerts, saying that an "after-action" would follow the search and rescue efforts. "Those questions are gonna be answered," he added.
