The NHC/TAFB gridded marine forecasts are now available on an experimental basis in the National Digital Forecast Database (NDFD).
Gridded forecasts of marine weather elements are available over the TAFB high seas forecast area of responsibility (AOR), which also includes the offshore waters forecast AOR.
The gridded marine parameters include:
These elements are available at a spatial resolution of 10 km for TAFB. The data have an initial temporal resolution of six (6) hours out to 144 hours or six (6) days. Plans are to eventually move toward a temporal resolution of 3 hours for all the marine centers contributing to the NDFD.
The grids are produced by forecasters through the AWIPS Graphical Forecast Editor (GFE) and should be available by 0330, 0930, 1530, and 2130 UTC each day.
With this implementation, forecasts for these elements are available from NDFD in the following standard methods:
More details regarding this experimental service are available in the Product Description Document from the online catalog of experimental NWS products and services.
Please see the public information statement for additional information.
The marine forecast images are available via the experimental NDFD graphical interface. Select the "Oceanic" option to view wind speed, wind gusts, significant wave heights, and hazards for the National Hurricane Center, Ocean Prediction Center, CONUS, Alaska, Hawaii, and Guam areas of responsibility.
The NDFD oceanic domain covers the Atlantic, Pacific, and Arctic basins for the offices issuing offshore waters and high seas forecasts. The upper right lat, lon for this grid is: 79.99N, 10.71E. The lower left corner lies directly on an NCEP grid 204 point, which coincides with all other Pacific region NDFD grids. The lower left lat, lon for this grid is 30.42S, 129.91E.
Specific information on the NDFD grid domains, including the oceanic domain, can be found at http://graphical.weather.gov/docs/ndfdSRS.htm.
Technical information on accessing and using NDFD elements can be found at http://ndfd.weather.gov/technical.htm.
The GRIB2 marine data on the NDFD oceanic domain can be downloaded at the following locations:

Note: Areas of the NDFD oceanic domain that coincide with the NDFD CONUS domain are included in the CONUS grids as well. Use the NDFD technical page to find access to the CONUS GRIB2 files.
The marine elements will remain experimental until the NWS assesses feedback and completes a technical analysis. At that time, the NWS will determine whether to move these experimental elements to operational status, discontinue them, or revise and extend the experimental feedback period.
