NOAA's National Ocean Service (NOS) has developed a Cook Inlet Operational Forecast System (CIOFS). CIOFS is based on a three-dimensional ROMS model that runs on NOAA's High Performance Computers (HPC). CIOFS provides water level, currents, water temperature and salinity nowcast and forecast guidance as well as interpolated winds from National Weather Service products. CIOFS runs four times per day and generates 6-hour nowcasts and 48-hour forecast guidance. CIOFS products include time series graphics at station locations and aerial animations of the whole Cook Inlet for all five parameters (wind, water level, currents, temperature and salinity).

NOAA's National Ocean Service (NOS) has developed a Columbia River Estuary Operational Forecast System (CREOFS). CREOFS is based on a three-dimensional SELFE model that runs on NOAA's High Performance Computers (HPC). CREOFS provides water level, currents, water temperature and salinity nowcast and forecast guidance as well as interpolated winds from National Weather Service products for five separate subdomains: Upper Columbia River subdomain, Middle Columbia River subdomain, Lower Columbia River subdomain, Columbia River Bar Entrance subdomain, and the mouth and offshore subdomain of the Columbia River. CREOFS runs four times per day and generates 6-hour nowcasts and 48-hour forecast guidance. CREOFS products include time series graphics at station locations and aerial animations of the Columbia River Estuary for all five parameters (wind, water level, currents, temperature and salinity).

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. LEOFS runs four times per day with 6-hour nowcast and 120-hour forecast for each cycle on the NCEP's Weather Climate Operational Supercomputer (WCOSS).

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). The objective of GLOFS is to produce nowcast and forecast guidance (displayed out to 24 hours) of total water level, current velocity, and water temperatures in the Lakes to be used by the commercial shipping, recreational boating, and emergency response communities.

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 objective of GLOFS is to produce nowcast and forecast guidance (displayed out to 24 hours) of total water level, current velocity, and water temperatures in the Lakes to be used by the commercial shipping, recreational boating and emergency response communities.

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). NGOFS provides water levels, currents, water temperature and salinity nowcast and forecast guidance as well as interpolated winds from National Weather Service products for the northern Gulf of America including seven ports at Matagorda Bay, Galveston Bay, Sabine Neches, Calcasieu/Lake Charles, Gulfport, Pascagoula Bay and Mobile Bay, six of which are CO-OPS PORTS® partners. NGOFS runs four times per day and generates 6-hour nowcasts and 48-hour forecast guidance. NGOFS products include time series graphics at station locations and aerial animations for all five parameters (winds, water levels, currents, temperature and salinity).

Oceanographic nowcasts and forecast guidance are scientific predictions about the present and future states of a water body (generally including water levels, currents, water temperature and salinity). These predictions rely on either observed data or forecasts from large-scale numerical models. A nowcast incorporates recent (and often near real-time) observed meteorological, oceanographic, and/or river flow rate data and/or analyzed (e.g. gridded) meteorological and oceanographic products. The wind data used to run CBOFS are based on the National Weather Service (NWS)/Real Time Mesoscale Analysis (RTMA) winds (for the nowcast) and an interpolation of the NWS North American Mesoscale (NAM)-12 atmospheric forecast model data (for the forecast). The NWS Global Forecasting System winds serve as backup winds for both the nowcast and forecast runs. CBOFS runs on NOAA's High Performance Computers (HPC) in a new Coastal Ocean Modeling Framework (COMF) developed by CO-OPS. All CO-OPS official real-time products, including nowcast and forecast guidance from CBOFS are monitored by the CO-OPS's Continuous Operational Real-Time Monitoring System (CORMS). CORMS provides 24 hour per day, 7 days per week monitoring and quality control of sensors and data in order to ensure the availability, accuracy, and quality of tide, water level, current, and other marine environmental information. CORMS is intended to identify invalid and erroneous data and information before application of the data by real-time and near real-time users.

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. TBOFS products include time series graphics at station locations and aerial animations of the whole Tampa Bay for all five parameters (wind, water level, currents, temperature and salinity).
