definition: A rising body of water (as in a stream, lake, or sea, or behind a dam) that overlaps its natural or artificial confines and that covers land not normally under water, esp. any relatively high streamflow that overflows its banks in any reach of the stream, or that is measured by gage height or discharge quantity. A Flood Advisory reports on conditions favorable for flooding and will provide locations in which flooding is more likely.
