Flash flooding is common enough around the crescent-shaped region from Dallas through the Hill Country, the area earned the nickname "Flash Flood Alley."

Lt. Gov. Dan Patrick signaled that he plans to push for the state to pay for sirens erected alongside the Guadalupe River in the wake of the devastating flash floods that led to the deaths of over 100 people.

Survivors have described the floods along the Guadalupe River as a “pitch black wall of death” and said they received no emergency warnings.
