The deadly Texas floods have brought the state's approach to land approvals, especially in flood-prone areas, under more scrutiny.

At least 27 campers and counselors at Camp Mystic perished in Friday's floods, with the total death toll in the floods now surpassing 100.

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.

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.

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.

At least 120 people are dead from the devastating flooding in the Texas Hill Country.

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

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