Flood involves water rising and overflowing its normal path. But a flash flood is a specific type of flood that appears and moves quickly across the land, with little warning that it's coming Many things can cause a flash flood. Generally they are the result of heavy rainfall concentrated over one area.
Most flash flooding is caused by slow-moving thunderstorms, thunderstorms that repeatedly move over the same area, or heavy rains from hurricanes and tropical storms. Dam failures can create the worst flash flood events. When a dam or levee breaks, a gigantic quantity of water is suddenly let loose downstream, destroying anything in its path Flash flood waters move at very fast speeds while floods do not move with greater speed.
