WWDISP - Displays active weather warnings, watches and advisories
   WWDISP map frame <keywords>
Parameters:
   map | map for the plot; use any predefined map in the MAP command,
         e.g., USA, MID, KS (def=use navigation of frame specified in
         the NAV keyword; no map is drawn)
   frame | frame number to display the output (def=current)
Keywords:
   COLor=tor svr toroutl svroutl win winoutl snowadv bliz blizoutl |
         graphics color levels of output (def=2 3 5 4 14 10 11 7 8 for
         sessions with more than 8 color levels; def=2 3 5 4 6 2 4 7 8 for
         sessions with 8 or less color levels), where:
            tor - color of tornado watch outlines and warning fill
            svr - color of severe thunderstorm watch outlines and
                  warning fill
            toroutl - color of county outlines drawn for tornado warnings
            svroutl - color of county outlines drawn for severe
                      thunderstorm warnings
            win - color of winter storm watch outlines and warning fill
            winoutl - color of zone outlines drawn for winter storm warnings
            snowadv - color of zone outlines drawn for snow advisories
            bliz - color of zone fill drawn for blizzard warnings
            blizoutl - color of zone outlines drawn for blizzard warnings
   DAY=bday eday | range of days to plot active bulletins (def=today bday)
   FIll=  | filling of the zones and counties under a severe thunderstorm,
            tornado, winter storm, or blizzard warning; uses the colors
            specified for 'svr', 'tor', 'win', and 'bliz' in the
            COLOR keyword; choose one of the following options (def=SOLID):
        =NONE | do not fill warning counties
        =SOLID | completely fill the warning counties with solid color
        =TRAN density | partially fill to give a transparent effect; range
                        is 2-10; a density value of n sets pixel interval
                        so every nth pixel is filled; larger values give
                        give a greater transparent effect (density def=4)
   GROup= | ADDE group name to search; the group name must be mapped to a
            server with weather text data (def=RTWXTEXT)
   NAV= | frame to use for navigation; specify a frame number or C for
          current frame (def=C); no map is drawn; you cannot use this
          keyword unless the default is used for the map parameter
   PLOt=BOX | plot severe thunderstorm and tornado watches as box outlines
       =COUNTY | plot watches as county outlines
       =NBOX height | plot watches as box outlines with watch number in
                      center of each box using specified pixel height
                      (def=NBOX 7)
   TIMe=btime etime | range of times to plot active bulletins
                      (def=current btime)
   TYPe=t1..tn | bulletin type(s) to plot; you cannot use TYPE with the
                 WATCH keyword; valid TYPEs are SEVWARN,SEVWATCH,TORWARN,
                 TORWATCH,WINWARN,WINWATCH,BLIZZARD,SNOWADV,ALL (def=ALL),
                 where:
                    SEVWARN, SEVWATCH=severe thunderstorm warnings, watches
                    TORWARN, TORWATCH=tornado warnings, watches
                    WINWARN, WINWATCH=winter storm warnings, watches
                    BLIZZARD=blizzard warnings, SNOWADV=snow advisories
                    ALL=all of the above
   WATch=num1..numn | severe thunderstorm and tornado watch numbers to plot;
                      the watches are plotted only if they are active during
                      the time period specified with DAY and TIME keywords
                      (def=all active watches during time period specified
                      with DAY&TIME); you cannot use WATCH with TYPE keyword
   WIDth=width | graphics line width of county outlines and watch boxes
                 (def=current GD command setting)
   WLIst=YES | plot watch list in upper-left of screen; the list includes
               the watch number, day of month and time it expires (def)
        =NO  | do not plot watch list
Remarks:
   If both watches and warnings are active, the watches are plotted before
   the warnings, regardless of which were issued first.

   Severe thunderstorm and tornado watches are plotted as either a box or
   county outlines.  The watch number prefaced by a T (tornado) or
   an S (severe thunderstorm) is plotted in the center of each box when
   PLOT=NBOX (the default) is used. Winter storm watches are always plotted
   as zone outlines.

   Counties and zones under a warning are filled in with the attributes
   specified in the FILL keyword and are outlined with the 'toroutl',
   'svroutl', 'winoutl' and 'blizoutl' colors specified in the COLOR
   keyword. Snow advisories are filled with the 'snowadv' color in a hatch
   pattern unless FILL=NONE is specified.

   If a range is specified with the DAY and TIME keywords, bulletins that
   are active in that time window are plotted.  For example, DAY=185 187
   TIME=21 3 specifies a window from 21:00 UTC on day 185 through 03:00 UTC
   on day 187.  If a single day and time is specified, bulletins that are
   active at that day and time are plotted.  The default is the current day
   and time.

   Tornado and severe thunderstorm watches that have been cancelled are
   considered expired and are not displayed.  Winter storm watches and all
   warning events that have been cancelled are displayed until their normal
   expiration time has passed.

   The map is drawn after all the watches and warnings are plotted.
