A study puts the spotlight on Texas as the leading U.S. state by far for flood-related deaths, with more than 1,000 of them from 1959 to 2019

The warning from the National Weather Service says that "excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. NWS sai

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.

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

As climate change increases the frequency of environmental disasters, experts say federal cuts could leave California and other states vulnerable in the years ahead.

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.

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.

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.

Weather model data shows the National Weather Service had reason to warn of higher flood risks. Still, meteorologists say the agency made reasonable predictions.

Catastrophic flooding struck central Texas on Friday as the Guadalupe River surged by more than 20 to 26 feet within 90 minutes, causing widespread devastation and forcing mass evacuations in Texas Hill Country. At least 80 people have been killed in the floods while others remain missing or displaced and more than 850 people required rescuing.
