FFMPACurrent State of Operations
• WFOs are responsible for issuing flash flood warnings, urban and small stream advisories, and flood warnings, as well as some experimental debris flow warnings.
• FFMP is a baseline AWIPS application with both server and display components.
• Many WFO forecasters use FFMP as a tool to assist with warning operations (Decision Assistance).

FFMPA Ancillary: FFG Update Method
• Elements of Transition method:– Apply a lag, to eliminate double-counting of precipitation in FFMPA analyses. This lag
will be equal to the Time Frame of the Guidance. (ie: 3-hr Guidance = 3-hr lag).– Apply an hourly interpolation scheme that manages precipitation in a way that greatly
enhances the Guidance values for the transition period and avoids increased under-warn situations that could exist with a lag-only approach.
