A Flash Flood Warning (SAME code: FFW) is issued when a flash flood is imminent or occurring in the warned area. A flash flood is a sudden, violent flood after a heavy rain, or occasionally after a dam break. Rainfall intensity and duration, topography, soil conditions, and ground cover contribute to flash flooding.
Most flash floods occur when there is a heavy amount of precipitation falling in an area and that water is then channeled through streams or narrow gullies. Flash floods may take minutes or hours to develop. It is possible to experience a flash flood without witnessing any rain. In this case, there would be heavy rain in areas upstream of your location.

Famous quotes containing the words flash, flood and/or warning:
“The point of the dragonflys terrible lip, the giant water bug, birdsong, or the beautiful dazzle and flash of sunlighted minnows, is not that it all fits together like clockwork--for it doesnt ... but that it all flows so freely wild, like the creek, that it all surges in such a free, finged tangle. Freedom is the worlds water and weather, the worlds nourishment freely given, its soil and sap: and the creator loves pizzazz.”
—Annie Dillard (b. 1945)
“So now it is vain for the singer to burst into clamor
With the great black piano appassionato. The glamour
Of childish days is upon me, my manhood is cast
Down in the flood of remembrance, I weep like a child for the past.”
—D.H. (David Herbert)
“Tonight I will speak up and interrupt
your letters, warning you that wars are coming,
that the Count will die, that you will accept
your America back to live like a prim thing
on the farm in Maine.”
—Anne Sexton (19281974)
