"NDFD" files are forecaster-generated wind and wave forecasts in grib format
from the US National Weather Service (NWS) for portions of E Pacific and
W Atlantic & Gulf offshore waters.
Please note that NDFD files are experimental and may not always be available.
Coverage is currently limited and will be expanded in the future.
NDFD forecasts should always be used in conjunction with the text bulletins.
