FFA
FFA is the ending valid time for the flood watches, the colors for
the flash flood and areal flood watches, a flag for plotting the
start and stop times, a flag for plotting the zone names for
the storms on the map, a flag for plotting the immediate cause for
the flooding, and a flag to outline the zone.

Flood watches that are valid at the ending time will be plotted on
the map. The ending time is given as a GEMPAK date/time string.
Any missing items from the string will be filled in by the system
time. The ending time may also be LAST and ALL. LAST will use the
system time and plot all current storm messages. ALL will plot all
the messages in the data files, whether they are active, cancelled
or expired.
The colors are separated by a semi-colon. If any color is set to 0,
that type of symbol will not be plotted. If any color is missing, a
default will be used. Defaults are red for warning, orange for watch,
and yellow for advisory.
The time flag is YES or NO and controls whether or not to plot
the start and stop times of the storm message on the map. The
default is NO.
The label flag is YES or NO and controls whether or not to plot
the zone name of the storm message on the map. The default is NO.
The immediate cause flag is YES or NO and controls whether or not to
plot the immediate cause of the flooding on the map. The default in
NO.
The outline flag is YES or NO and controls whether to outline the storm
zone instead of plotting a marker. The default is NO. The outline
colors are those specified previously. If a message is a "test" only,
a hollow marker will be plotted at the zone centroid to indicate this,
and no outlining will be done.
The line widths of warning, watch, and advisory are valid only when
the outline flag is YES. The line widths are separated by a semi-colon.
If any line width is missing or less than 0 or greater than 10, a
default value (3) will be used.
