Flash floods can strike any time with little or no
warning. City streets can become rivers in seconds. Most flash flooding is
caused by slow-moving thunderstorms, thunderstorms repeatedly moving over the
same area, or heavy rains from hurricanes and tropical storms. Blocked catch
basins, storm drains, water main breaks, and sewer lines can also lead to
flooding.
