Meanwhile, anguished parents waited for word on the 10 young campers still missing from Camp Mystic, which was hit hard by floodwaters.

Flash-flood warnings and watches remain in effect for parts of Central Texas into Sunday evening, dimming hopes that more survivors would be found.

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."
