Nearly a decade ago, neighboring counties, Guadalupe and Comal, installed flood sirens. Nearby New Braunfels regularly tests its outdoor warning system, which is designed to alert residents to flash floods that are common in the area. But in Kerr County, officials admitted over the weekend that no such system exists.

At least 82 people are dead after heavy rain led to "catastrophic" flooding in Texas. Kerr County was hit the hardest, with at least 75 deaths, including 27 children. President Donald Trump signed a disaster declaration for the county and the Federal Emergency Management Agency is on the ground there.

Kerr County, Texas Judge Rob Kelly told a reporter that the county does not have a warning system, saying that "no one knew this kind of flood was coming."
