In the wake of catastrophic flooding in Central Texas that left more than 125 people dead and dozens missing, federal and state officials have warned residents and donors about a surge in disaster-related scams designed to exploit vulnerable families and charitable givers.

The region of Texas that suffered tremendous loss last week because of heavy rain and flooding is once again in danger of taking in more water. On Sunday morning, the National Weather Service issued a flash flood warning for the epicenter of the catastrophic Independence Day flooding event.
