On another holiday weekend a decade ago, McComb and his family were vacationing in Wimberley when torrential rain forced the Blanco River to swell, carrying the home they were in downstream. McComb made it to shore, but his wife and children didn't survive. He said his daughter, Leighton, was never found.

With more rain on the way, the risk of life-threatening flooding was still high in central Texas on Monday even as crews search urgently for the missing.

Extreme flooding has left at least 78 dead in Texas. 10 children and one counselor remain missing from Camp Mystic, a Christian girls camp.
