Central Texas flooding has prompted emergency repairs on Loop 360. Drivers should expect lane closures on Loop 360 near Spicewood Springs Road through September.

Just over a week after deadly flash floods swept through Texas Hill Country, the region may once again face a life-threatening deluge as slow-moving thunderstorms bring heavy rain, flash flooding, and rapid river rises to parts of central Texas Sunday.

The flooding Saturday comes on the heels of catastrophic conditions Friday morning in Central Texas, primarily in the Kerrville area. More than 40 people have died in flood waters resulting from heavy rain in Kerr County, while search-and-rescue operations are ongoing. A group of more than 20 girls with Camp Mystic in Kerrville remain missing.

The Hill Country has a hold on the hearts of many Texans, meaning the suffering caused by the disaster is reaching as far as the region’s appeal.

A flood watch is issued when conditions are favorable for flooding, according to the National Weather Service. It doesn't guarantee flooding will occur, but it means flooding is possible. Areas north of Dallas to the Red River will remain under flood watch until 7 a.m., according to the NWS in Fort Worth.

The term "100-year flood" implies that the event is a rare occurrence; however, dozens of such storms have inundated the United States over the past year alone, prompting concern that they are occurring more frequently as the Earth's climate continues to warm.
