A flash flood is a rapid flooding of low-lying areas: washes, rivers, dry lakes and basins. 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 occur after the collapse of a natural iceor 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 less than six hours between rainfall and the onset of flooding.[1] The water that is temporarily available is often used by plants with rapid germination and short growth cycles and by specially adapted animal life.[citation needed][dubious – discuss]
