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.

As search and recovery efforts continue following the deadly floods, NWS warns of isolated flash floods due to the possibility of heavy rain this weekend.⛈️

A memorial service was held in Kerr County, Texas on Friday to honor the victims and those still missing from flooding that recently struck the region.

The alert says there is a high chance the Guadalupe River will flood on Sunday. They’re asking for all people, equipment and vehicles to move away from the river immediately. They also said all volunteer operations are suspended until further notice, stating “safety of lives is the highest priority.”

Officials in Kerr County, where the majority of the deaths from the July 4 flash floods occurred, have yet to detail what actions they took in the early hours of the disaster.

The reporter said that several families were angry because they felt that alerts for the flood did not go out in time.

President Donald Trump travels to Texas on Friday amid growing questions about how local officials responded to the devastating floods, as well as questions about the federal response -- including FEMA's fate -- that he has so far avoided.
