The risk of the catastrophic flooding that struck Texas Hill Country as people slept on July 4 and left at least 120 dead was potentially underestimated by federal authorities, according to an ABC News analysis of Federal Emergency Management Agency data, satellite imagery and risk modeling.

Texas on Saturday faces an upper-atmosphere wave of low pressure that could trigger storms and an increasingly deep flow of Gulf moisture.

More cabins and buildings at Camp Mystic — the tragic site of more than two dozen deaths in the Texas flood — were at risk of flooding than what the federal government had previously reported, according to new analysis from NPR,

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.

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.

North Texas is currently not under a flood watch, but that could change as storm chances increase this weekend. Scattered thunderstorms are expected Saturday and Sunday, with a Level 2 out of 4 risk for excessive rainfall on both days.

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.

Officials criticized the Trump administration for cutting funding to programs that provide meteorological data.

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.
