Using readily available and free GRIB weather forecast files, wind speed, wind direction, pressure, air and sea temperature are plotted on the chart. Both traditional vectors with barbs or Beaufort scale filled vectors are available. Selecting the forecast is as easy as picking the date/time from the list.
I use for a long time the grib files and the viewer. A perfect service/program but It would be nice to have a Mac version (may be if we make a financial contribution, not irrational for this good service, it's getting higher on the priority list).
MacENC and GPSNavX read all GRIB 1 format
