Emergency officials are starting to focus on alert systems as they search for answers about how the flash flooding swept away so many.

Flood watches have been issued by the National Weather Service until at least 7 p.m. CT July 6 in Hill Country and along the I-35 corridor. The Weather Prediction Center added that scattered thunderstorms are likely to drop "torrential downpours over sensitive soils across parts of the Texas Hill Country."

Eight, mostly rural, high school FFA chapters are joining forces to gather supplies and gift cards for flooding victims near Kerrville.
