Hello GEMBUD users,

 

Has anyone ran into the problem of getting county or zone filled flash flood
watches.  I've searched through the support requests and mailing lists with
no luck.

 

Using GPMAP, I've been able to outline the flood watch zone OR place a
marker in the center of each flood watch zone using the FFA variable.
However, there doesn't appear to be an ability for GPMAP to color fill the
flood watch zone similar to how (WOU/WCN) can color fill severe thunderstorm
/ tornado watch zones.

 

GPMAP commands to generate outline of flood watch zones (FFA), and color
filled severe thunderstorm/tornado watch zones are below:

 

MAP=9

MSCALE=0

GAREA=14;-120;47;-40

PROJ=str/90;-95;0

PANEL=0

TITLE=0

CLEAR=YES

DEVICE=gif | watches.gif

WOU=last|6;8|NO|NO|NO|NO|NO|NO|YES/6;8|YES

FFA=last|4;4|NO|NO|NO|YES

 

A copy of "coltbl.xwp" is located in the working directory (in order to edit
the colors).

 

Using GPWARN, I've been able to color fill the severe thunderstorm, tornado,
and flood warnings using the following commands:

 

MAP=9

GAREA=14;-120;47;-40

PROJ=str/90;-95;0

PANEL=0

TITLE=0

CLEAR=YES

DEVICE=gif | warnings.gif

WWFIL=floodwarn;tstormwarn;tornadowarn

WWS=current

WWATT=0/-1400

OUTPUT=t

 

A copy of "gwarn.config" is located in the working directory (in order to
edit the colors).

 

The GPWARN documentation says the following products can be plotted in the
"WWFIL" parameter

                                   PIL

   Tornado Warnings                TOR

   Severe Thunderstorm Warnings    SVR

   Flood Watches                   FLA|FFA

   Flood Warnings                  FLW|FFW

   Winter Weather Bulletins        WSW

   Non-precipitation Bulletins     NPW

   Special Weather Statements      SPS

 

I'm not sure what name (i.e. floodwarn) or flood watch file should be put
into WWFIL.


The names found in $GEMTBL/config/datatype.tbl are below:

! Text files for warnings (convenience access)

TORNADOWARN  $TEXT_WARN/TOR            YYYYMMDDHH.TOR
CAT_NIL  SCAT_NIL   72   4320     60      OFF/0/0

TSTORMWARN   $TEXT_WARN/SVR            YYYYMMDDHH.SVR
CAT_NIL  SCAT_NIL   72   4320     60      OFF/0/0

NONPCPWARN   $TEXT_WARN/NPW            YYYYMMDDHH.NPW
CAT_NIL  SCAT_NIL   72   4320     60      OFF/0/0

WINTERWARN   $TEXT_WARN/WSW            YYYYMMDDHH.WSW
CAT_NIL  SCAT_NIL   72   4320     60      OFF/0/0

FLOODWARN    $TEXT_WARN/flood          YYYYMMDDHH.flood
CAT_NIL  SCAT_NIL   72   4320     60      OFF/0/0

 

Several input parameter links on
(http://www.unidata.ucar.edu/cgi-bin/gempak/manual/programs_index?gpwarn)
are broken which might give the answer I'm looking for.

[WWFIL, WWS, WWATT]

 

Does anyone know whether it's possible to plot county or zone filled flash
flood watches?

 

Thanks for your help,

Evan
