The Associated Press has assembled an approximate timeline of the 48 hours before, during and after the deadly flash flood, beginning with the activation of the state’s emergency response resources on July 2 — the same day Texas signed off on the camp’s emergency plan for disasters.

Officials in Texas Hill Country are starting to focus on alert systems like the one in Comfort as they search for answers on how the flash flooding swept away so many in Kerrville.

Before hundreds of first responders and volunteers from around the country came to help, it was the local residents of Texas Hill Country who faced down a deadly wall of water along the Gaudalope River and witnessed terrifying scenes.

Despite officials urging civilians to stay away, volunteers have joined the search for missing people and the cleanup on the Guadalupe River.
