Maps show how heavy rainfall and rocky terrain helped create the devastating Texas floods that have killed more than 120 people.

Many questions remain about how storms caught off guard an area prone to flooding and led to the second deadliest flood in Texas history. Here’s what we know. Flooding death toll increases to 132;

INGRAM, Texas — Search and rescue crews from Mexico were forced to halt their operations on the Guadalupe River in Ingram, Texas today as rain caused water levels to rise, complicating efforts to find victims of the deadly July 4th floods.

A large percentage of people still unaccounted for were probably visiting the area, Kerr County Judge Rob Kelly said.

New flood warnings have been issued along the Guadalupe River in Texas less than two weeks after flooding killed more than 100 people.

State and local officials said they did their best to coordinate evacuations and rescues, but better cellphone service might help in future floods.

The organizations working together to help the flood victims said that 'no additional in-kind donations (clothing, food, supplies) are needed in Kerrville.' They said the best way to help is with monetary donations.

The official tally of storm-related deaths across Texas rose to 131 on Monday as authorities warned of yet another round of heavy rains 10 days after a Hill Country flash flood that transformed the Guadalupe River into a killer torrent.

With more than 170 still missing, communities must reconcile how to pick up the pieces around a waterway that remains both a wellspring and a looming menace.

The Texas Hill Country has been notorious for flash floods caused by the Guadalupe River. Here's why the area is called "Flash Flood Alley."

As the water rises, so does the Kerr County community, especially one man who reunited a brother and sister, swept away in the flood.
