Kerr County failed to secure a warning system, even as local officials remained aware of the risks and as billions of dollars were available for similar projects.

Some regions in the mid-Atlantic are also facing risks of flooding. On Sunday, Tropical Storm Chantal flooded parts of North Carolina, where more than 10 inches of rain fell near the Chapel Hill area. The Haw River, near Bynum, North Carolina, crested to nearly 22 feet, the highest crest on record there, as a result of those heavy rains.

More than 100 people are dead and 150 known to be missing in Texas Wednesday from flooding but questions remain about how the effects of the deadly disaster could have been mitigated.

North Carolina, New Mexico and Texas have all suffered deadly floods in the last week after intense rain storms. Climate change is causing even more rain to fall during the heaviest storms.

The president has defended his administration's response to the fatal flooding amid criticism that federal assistance could have been provided more quickly.

Days after flash floods killed over 100 people during the July Fourth weekend, search-and-rescue teams are using heavy equipment to untangle and peel away layers of trees, unearth large rocks in riverbanks and move massive piles of debris that stretch for miles in the search for the missing people.
