Kerr County authorities issued a new Guadalupe River evacuation notice and suspended search operations as more heavy rains inundated the area early

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.
