Back-to-back flooding disasters in recent years — in Texas, New Mexico and Kentucky, among many others — have showed that preparing for flash flooding is a new necessity as the planet warms.

A flash flood is a rapid rise of water along a stream or in a low-lying urban area, the National Weather Service said. Flash flooding can result from slow-moving thunderstorms, from numerous thunderstorms that develop repeatedly over the same area, or from heavy rains associated with tropical cyclones.

There are reports some cloud seeding occurred a few days before the Texas flash flood. But it’s important to understand that cloud seeding has a relatively short-term effect in that a certain cloud is seeded and perhaps turns into one individual rain cloud or even a thunderstorm. The increased rainfall would not last for days.

Recent flash flooding in Texas​, New Mexico​ and North Carolina​ is highlighting the extreme danger of these natural disasters and the need to be prepared.
