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.

Briefing mediapersons over Texas floods, Kerr County Sheriff Larry L Leitha said the first flash flood notification came between 4 AM and 5 AM.

Kerr County, Texas, lacked a “last mile” warning mechanism that could have saved residents before the deadly floods devastated the area, including a children’s summer camp, killing more than 80 people.
