At least 13 fatalities were reported Friday as devastating floods slammed Texas' Hill Country with water rescues taking place along the Guadalupe River, officials said.

Local officials have faced angry questions about whether they could have warned people of dangerous flash floods in Texas Hill Country sooner. Rescue teams from neighboring states and Mexico have joined local efforts to search for survivors,

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.
