Flash flood

rapid flooding of low-lying areas, often caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or melt water from ice or snow

A flash flood is very quick flooding of low-lying land, usually without prior warning. It may be caused by heavy rain or water from melted ice or snow. Flash floods can also happen after the collapse of a dam.[1] A tsunami causes similar problems but is not usually called a flash flood.
