Update to add links for the experimental gridded forecasts
and to extend comment period through December 31, 2018

The NWS National Centers for Environmental Prediction (NCEP)
Tropical Analysis and Forecast Branch (TAFB) will continue to
provide gridded forecasts of five marine weather elements to
the National Digital Forecast Database (NDFD) on an experimental
basis for its Pacific Basin offshore waters and high seas
forecast areas of responsibility.

The NCEP Ocean Prediction Center (OPC) also will continue to
provide gridded forecasts of five marine weather elements to
the NDFD on an experimental basis for its offshore waters in
the Pacific basin. TAFB began production of the experimental
NDFD grids on March 20, 2013, for all of its offshore and high
seas Area of Responsibility (AOR). OPC began producing
experimental offshore grids on May 1, 2013; experimental high
seas forecasts grids for the Pacific Basin are under

The marine weather elements that will remain experimental in the
Pacific Basin from TAFB and OPC are 10-m wind speed, 10-m wind
direction, 10-m wind gusts, significant wave heights, and marine
hazards. The experimental gridded forecasts can be found at:
