At least 161 are still unaccounted for after the July Fourth floods that saw the waters of the Guadalupe rise to historic levels in Central Texas, officials with Kerr County said Friday. Authorities have confirmed 103 deaths, 36 of whom are children.

Sunday morning recovering efforts were suspended in Kerr County due to heavy rainfall and a new flash flood warning issued for the Hill Country.

More rain and flash flooding is ongoing throughout Central Texas, with life-threatening flash flood warnings in effect for many areas around the Hill Country, including hard-hit Kerr County. Search and rescue missions have been paused for Sunday,

As the search for victims continues, county officials say "additional resources" are being deployed as the "mission efforts become more technical."

FEMA records obtained by NBC 5 Investigates show that Kerr County officials did not use FEMA’s Integrated Public Alert & Warning System to send warnings with safety instructions to all mobile phones in the affected area during critical hours as the flooding began on July 4.

In the last nine years, federal funding for a system has been denied to the county as it contends with a tax base hostile to government overspending.

Kerr County first tried to secure $1 million for a flood warning system in 2017, but could not. Could such a system have prevented loss of life on July 4?

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