Since 2016, the topic of a "flood warning system" for Kerr County has come up at 20 different county commissioners' meetings, according to minutes. The idea for a system was first introduced by Kerr County Commissioner Thomas Moser and Emergency Management Coordinator Dub Thomas in March 2016.

There are more than 100 emergency personnel on the ground working to reunite families, the sheriff said. A large-scale search and rescue effort is ongoing.

During a press conference with officials of Kerr County, Texas, reporters asked tough questions about the handling of the flood emergency system.
