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

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.

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.

Following storms and floods that turned deadly over the holiday weekend, flood warnings remained in effect across central Texas on Monday

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

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.

As a climate scientist who calls Texas home, I can tell you that the Hill Country of Texas is no stranger to flooding. Meteorologists often refer to it as “Flash Flood Alley” because of its steep terrain, shallow soils, and its history of sudden and intense rainfall.

President Donald Trump spoke with Fox News host Will Cain about rescue efforts in Kerrville, Texas after catastrophic flash floods on "The Will Cain Show."
