Effective on or about October 25, 2022 beginning at 18z Coordinated Universal Time (UTC), the NOAA/National Ocean Service’s framework
for Operational Forecast Systems (OFS) will be updated to version 3.5. The update includes:
NOAA provides forecast guidance of oceanographic information to help mariners safely navigate their local waters. This national network of hydrodynamic models provides users with operational nowcast and forecast guidance (out to 48 hours) on parameters such as water levels, water temperature, salinity, and currents. These forecast systems are implemented in critical ports, harbors, estuaries, Great Lakes and coastal waters of the United States, and form a national backbone of real-time data, tidal predictions, data management and operational modeling.
