Rescuers searched the Guadalupe River for survivors of the Texas floods that killed more than 100 people over the July Fourth holiday weekend, with an unknown number of people still missing. The basin area was crowded with families and campers preparing to enjoy the holiday when pounding rain brought about catastrophic flash floods just before dawn Friday.

Authorities overseeing the search for flood victims in Texas said Monday that they will wait to address questions about weather warnings and why some summer camps did not evacuate ahead of the catastrophic flooding that killed nearly 90 people over the July Fourth weekend.

Central Texas was ravaged by floods over the July 4th weekend leading to deaths, including children at Camp Mystic, an all-girls summer camp.
