The catastrophic Central Texas floods have claimed at least 121 lives and left 173 missing, as a report reveals that Kerr County officials were repeatedly denied state funding for an emergency flood warning system.

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.

Twice, the Texas Division of Emergency Management turned down Kerr County's requests for money to improve flood warnings.

Here's what to know about the deadly flooding, the colossal weather system that drove it and ongoing efforts to identify victims.

If you have a missing person, email [email protected] with the name and description of the missing person. You can also provide photos to aid in identification. The reunification center for those waiting on word about missing persons is at Calvary Temple Church, 3000 Loop 534.

As the recovery efforts continue after devastating flash floods in Texas Hill Country, NBC Dallas-Fort Worth obtained FEMA records revealing new details about alerts that were not sent when the flooding began.

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.
