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.

Texas county commissioners previously suggested "river calling," an informal phone chain used by summer camps, would be better than installing new flood sirens.

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