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).

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 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 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 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).

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) 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).
