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.

KHOU 11 Meteorologist Pat Cavlin says it's impossible to determine exactly where the heaviest of rain will fall, but everyone in risky areas should stay aware.

A surge of deep tropical moisture returns to Texas this weekend. Here's where the risk of flash flooding is highest in the state this weekend.

Search crews continued the grueling task of recovering the missing as more potential flash flooding threatened Texas Hill Country.

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

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 areas that see rainfall and increased cloud cover, temperatures are expected to remain below seasonal averages into next week, providing some relief from the summer heat. However, much of central and southern Texas, areas in the recovery phase from the catastrophic flooding, will face dangerous heat instead of renewed flooding.

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.

Federal regulators removed dozens of Camp Mystic buildings from a 100-year flood map as the camp looked to expand.
