Darrell,

I plot tropical storm tracks over the Atlantic, such as are shown at:
http://www.unidata.ucar.edu/staff/chiz/storm/tropic/atlantic.gif

You might need to make sure your longitudes are West=negative.

A quick check to make sure your stations have the expected lats/lons
is to use SFPARM=slat;slon in sflist. If your station table is off a column,
or not using the appropriate sign convention for longitude, etc, then that
should be evident.

If you continue to have problems, then feel free to send
a sample of your station table, sfedit data, and parameters you
are using for sfmap and I'll look at what you are doing.
