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

NOAA's National Ocean Service (NOS) has developed a Gulf of Maine Operational Forecast System (GoMOFS). Based on Rutgers University's Regional Ocean Modeling System (ROMS), this OFS is to forecast water levels, currents, temperature and salinity for Gulf of Maine and its adjacent coastal area. The forecasts, which extend out to 72 hours, will support the maritime user community in navigation, emergency response, and ecological forecasts, etc. GoMOFS runs on NOAA's High Performance Computers (HPC) in a new Coastal Ocean Modeling Framework (COMF) developed by CO-OPS.

NOAA's National Ocean Service (NOS) collaborated with the Great Lakes Environmental Research Laboratory (GLERL) in developing and transitioning the new generation of Lake Erie Operational Forecast System (LEOFS) to operations, to provide higher-resolution forecast guidance of water level, currents and water temperature. The upgraded LEOFS uses the Finite Volume Community Ocean Model (FVCOM) as its core ocean circulation model and has extended the forecast horizon to 120 hours.

The Lake Huron Operational Forecast System (LHOFS) is a NOAA project aimed at providing improved predictions of water levels, currents and water temperatures in Lake Huron 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 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).
