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: Forced FFG

• Applies user-defined FFG– Strict override– modification

• For a user-defined data source

• For a user-defined period of time

• For a user-defined area– County– Basin– Entire domain

• That is retrievable• Desire Geographic

FFMPA Ancillary: Ingest Data Monitor

• Notes health of data ingest, of interest to FFMPA

• User-defined determination of “too old”

• HTML Interface

• Special rules for RADAR DHR

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.
