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

A massive Texas search and cleanup effort was set to enter its fifth day Tuesday in response to Guadalupe River flooding that surged through the area on July 4.

Dozens of people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.
