While the search continues for survivors of the Texas flood, a clearer picture has emerged of how it turned catastrophic, and how quickly it escalated in the early hours of July 4.

Rescuers searched the Guadalupe River for survivors of the Texas flash 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.
