Flash Flood Guidance (FFG)

			About Flash Flood Guidance (FFG): FFG provides an estimate of the amount of rainfall over a specific area during a given duration of time that is required to cause small streams to overflow their natural bank. The latest FFG is referenced when issuing flash flood watches and warnings. These 1, 3, and 6-hour FFG products are issued twice daily around 11am and 9pm and are meant to be used only as guidance. Topography and urbanization also affect flash flooding.
