Travis and Williamson counties have issued local disaster declarations and dozens of people have been rescued from floodwaters.

The flooding Saturday comes on the heels of catastrophic conditions Friday morning in Central Texas, primarily in the Kerrville area. More than 40 people have died in flood waters resulting from heavy rain in Kerr County, while search-and-rescue operations are ongoing. A group of more than 20 girls with Camp Mystic in Kerrville remain missing.

When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.

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."
