★Amazing flash flood in History caught on camera-angry mother nature part-2

It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields. Flash floods may also occur after the collapse of a natural ice or debris dam, or a human structure such as a man-made dam, as occurred before the Johnstown Flood of 1889. Flash floods are distinguished from regular floods by having a timescale of fewer than six hours between rainfall and the onset of flooding. The water that is temporarily available is sometimes used by certain plants for growth. However, plants that thrive in drier areas can be harmed by flooding, as the plants can become stressed by a large amount of water.
