Kerr County repeatedly 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.

At least 27 campers and counselors were killed at Camp Mystic during the devastating Texas floods. Some are still missing.

The data also highlights critical risks in other areas along the Guadalupe River in Kerr County, revealing more than twice as many Americans live in flood prone areas than FEMA's maps show.

When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.

In what experts call "Flash Flood Alley," the terrain reacts quickly to rainfall steep slopes, rocky ground, and narrow riverbeds leave little time for warning.

New data reveals FEMA missed major flood risks at Camp Mystic, where over two dozen died in the Texas flood. And, U.S. measles cases hit the highest level in over three decades.

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.

Flash floods last week in Texas caused the Guadalupe River to rise dramatically, reaching three stories high in just two hours
