The Lake Michigan Operational Forecast System (LMOFS) is a NOAA project aimed at providing improved predictions of water levels, currents and water temperatures in Lake Michigan to the user communities. Similar systems are operational in the other 4 Great Lakes as well. Collectively these form the Great Lakes Operational Forecast System (GLOFS).

The Lake Ontario Operational Forecast System (LOOFS) is a NOAA project aimed at providing improved predictions of water levels, currents and water temperatures in Lake Ontario to the user communities. Similar systems are operational in the other 4 Great Lakes as well. Collectively these form the Great Lakes Operational Forecast System (GLOFS).

The Lake Superior Operational Forecast System (LSOFS) is a NOAA project aimed at providing improved predictions of water levels, currents and water temperatures in Lake Superior to the user communities. Similar systems are operational in the other 4 Great Lakes as well. Collectively these form the Great Lakes Operational Forecast System (GLOFS).

NCEI manages the long-term archive of model output files for the hydrodynamic model-based Operation Forecast Systems (OFS) developed and implemented by the National Ocean Service (NOS) to support navigation in U.S. waters. This system is a national network of hydrodynamic models that provides operational nowcast and forecast guidance (out to 48 hours) on parameters such as water levels, water temperature, salinity, and currents.

NOAA's National Ocean Service (NOS) has developed the Northern Gulf of America Operational Forecast System (NGOFS) including two nested Northeast and Northwest Gulf of America Operational Forecast Systems (NEGOFS/NWGOFS). NGOFS is based on a three-dimensional FVCOM model that runs on NOAA's High Performance Computing System (HPC).

NOAA's National Ocean Service (NOS) has developed a Port of New York and New Jersey Operational Forecast System (NYOFS). The cornerstone of NYOFS is an advanced three-dimensional hydrodynamic model that uses realtime water-level and wind data and other inputs to predict the water levels and currents at thousands of locations throughout the harbor. The system runs in both nowcast and forecast modes. The nowcast mode is driven by real-time water levels and winds from the New York/New Jersey PORTS®, and is updated hourly. The forecast mode performs 30-hour forecasts four times a day.

NOAA's National Ocean Service (NOS) has developed a San Francisco Bay Operational Forecast System (SFBOFS). SFBOFS is based on a three-dimensional FVCOM model that runs on NOAA's High Performance Computing System (HPCS). SFBOFS provides water levels, currents, water temperature and salinity nowcast and forecast guidance as well as interpolated winds from National Weather Service products for two subdomains: the San Francisco Bay and the San Francisco Bay Entrance. SFBOFS runs four times per day and generates 6-hour nowcasts and 48-hour forecast guidance.

NOAA's National Ocean Service (NOS) has developed a St. John's River Operational Forecast System (SJROFS). The Environmental Fluid Dynamics Code (EFDC) has been used to perform operational nowcasts and forecasts for the Lower St. John's River. The EFDC model solves the three-dimensional, vertically hydrostatic, free surface, turbulent averaged equations of motions for a variable density fluid. The physics of the EFDC model and many aspects of the computation scheme are equivalent to the widely used Blumberg-Mellor model (POM).

NOAA's National Ocean Service (NOS) has developed a Tampa Bay Operational Forecast System (TBOFS). TBOFS is based on a three-dimensional ROMS model that runs on NOAA's High Performance Computers (HPC). TBOFS provides water level, currents, water temperature and salinity nowcast and forecast guidance as well as interpolated winds from National Weather Service products. TBOFS runs four times per day and generates 6-hour nowcasts and 48-hour forecast guidance.
