Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

The Houston Texans were the first to announce their donations on Saturday, July 5, with more coming throughout the week. The Dallas Cowboys and the NFL Foundation joined the Texans on Sunday, July 6, with each contributing $500,000 in a $1.5 million total donation.

Kerr County, Texas and national search and rescue operations will continue Monday around the Guadalupe River, where families wait for news of their loved ones.

Crews are using construction equipment to clear vehicles, trees and homes in a race to locate the 161 people still missing since Friday’s devastating flood.

At least 120 people have been found dead in nearly a week since heavy rainfall overwhelmed the river and flowed through homes and youth camps in the early morning hours of July 4. Ninety-six of those killed were in the hardest-hit county in central Texas, Kerr County, where the toll includes at least three dozen children.

Daniel Morales, assistant chief of the Comfort Volunteer Fire Department, believes that long, flat tone the morning of July Fourth saved lives.
