Search and rescue efforts continued overnight in Texas for the dozens of people still missing from the devastating flash floods that have killed more than 100 people. Meanwhile, the Texas flood alert system is facing scrutiny over how much warning locals were given ahead of the flash floods.

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.
