The death toll from catastrophic flooding in Texas over the July Fourth weekend has surpassed 100 as the massive search continues for missing people.

The search for unlikely survivors grew more desperate four days after one of the deadliest U.S. floods in decades. Ten campers and a counselor are among those still missing.

The search for missing bodies is ongoing along Texas’ Guadalupe River after catastrophic and deadly flooding killed at least 89 people following a torrential downpour early Friday morning.
