Scholars and designers of early warning systems say that there are still huge gaps in our ability to predict flash floods and warn those at risk.

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.

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.

Flash floods in Texas have killed at least 107 people over the Fourth of July weekend, with more than 160 still missing.

Search crews continued the grueling task of recovering the missing as more potential flash flooding threatened Texas Hill Country.

Straighter, smoother streams flow more violently than those that meander due to a reduction in friction. Areas with steeper terrain can see water accelerate downhill at a much faster rate causing a more destructive flash flood than flatter, open areas.

More than 111 people have died across six counties after flash flooding from heavy rain began affecting the state last week.

This is false. It is not possible that cloud seeding generated the floods, according to experts, as the process can only produce limited precipitation using clouds that already exist.

Here's what to know about the deadly flooding, the colossal weather system that drove it and ongoing efforts to identify victims.

An analysis of National Weather Service job vacancies found that in more than a third of offices overseeing flash flood hotspots, one or more of three senior leadership roles are open.
