Emergency crews suspended their search for victims of catastrophic flooding in central Texas on Sunday morning amid new warnings that additional rain would again cause

FEMA records show officials in Kerr County, Texas, did not use FEMA's system to send warnings to phones in the hours as the flooding began on July 4.

A Flash Flood Emergency and numerous Flash Flood Warnings were issued in Central Texas on Sunday morning after torrential rain led to the rapid rise of the Lampasas River.

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.

Over 12,000 volunteers have already assisted in Kerr County, according to the Texas Division of Emergency Management.

Ninety-six of those killed were in the hardest-hit county in central Texas, Kerr County, where the toll includes at least 36 children. State officials vowed to continue searching for over 160 people still missing but have acknowledged the dwindling chances of finding survivors alive a week after the disaster.

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.

Local officials in Kerr County continue facing public scrutiny after days of seeming to deflect questions about their preparedness and response to the July 4 flash flood that left dozens dead.
