In an announcement issued this week, NOAA advised that its Pacific Basin gridded forecasts are good to go. That’s just in time for the start of the 27th Baja Ha-Ha and the ‘heading south’ cruising season.
NOAA’s offshore and high seas gridded forecasts for the Pacific Basin transitioned from experimental to operational on October 28 — yesterday!
The forecasts originate from the Tropical Analysis and Forecast Branch (TAFB) of the National Hurricane Center (NHC), the Weather Forecast Office (WFO) in Honolulu, Hawaii, and the Ocean Prediction Center (OPC).
There are five elements making the transition: 10-meter (33-ft) wind speed; 10-meter wind direction; 10-meter wind gusts; significant wave heights (or “seas”); and marine hazards. Transitioning these forecasts to operational status is another milestone for the NWS National Digital Forecast Database (NDFD) and follows a similar move in December 2017 with the Atlantic offshore grids. Users do not need to take any action when the experimental forecasts transition to operational status.
An example of the wind and wave grids from NHC/TAFB is shown below for a forecast valid at 1200 GMT Tuesday, October 26, 2021:
