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 legislator must be in advance of his age.
Across the mind of the statesman flash ever and anon the brilliant, though partial, intimations of future events.... Something which is more than fore-sight and less than prophetic knowledge marks the statesman a peculiar being among his contemporaries.”
—Woodrow Wilson (1856–1924)
“Myths, as compared with folk tales, are usually in a special category of seriousness: they are believed to have “really happened,” or to have some exceptional significance in explaining certain features of life, such as ritual. Again, whereas folk tales simply interchange motifs and develop variants, myths show an odd tendency to stick together and build up bigger structures. We have creation myths, fall and flood myths, metamorphose and dying-god myths.”
—Northrop Frye (1912–1991)
“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 (1928–1974)
