Marck,

    The WAFS grids are a thinned lat-lon grid which is not supported by
grib2ctl.pl.
If you have a linux box, you can convert the WAFS grid to a 1x1 grid by

         copygb -g3 -x wafsgfs_L_t12z_intdsk00 out.grib

and run grib2ctl.pl on out.grib.  Adding thinned lat-lon grids to
grib2ctl.pl is not
a 3-lines change (more like a 100+ lines change).

       Yours,
