A swift-moving flood that swept through the Hill Country of Texas on Friday, killing at least 79 people and leaving many more missing, was a flash flood.

Barry dissipated as a tropical depression four days before its remnants helped trigger the deadly Texas flash flood. And it's far from the only example of deadly inland flooding we've seen.

The threat of heavy rain is “slight” for this weekend, but with the ground fully saturated in Kerr County even small amounts of rainfall could cause flooding.
