Notice: The LOOFS outputs including graphics are currently under evalation. Please do not attempt to use the outputs operationally for navigation and/or recreation purposes.

The Lake Ontario Operational Forecast System (LOOFS) was jointly developed by NOAA/National Ocean Service's (NOS) Center for Operational Oceanographic Products and Services (CO-OPS) and Office of Coast Survey (OCS), the Great Lakes Environmental Research Laboratory (GLERL), the NOAA/National Weather Service's (NWS) National Centers for Environmental Prediction (NCEP) National Central Operations (NCO), and the University of Massachusetts-Dartmouth.

LOOFS uses the Finite Volume Community Ocean Model (FVCOM) to provide users with nowcast (analyses of near present) and forecast guidance of water levels, currents, and water temperature out to 120 hours, four times per day. By invoking advanced model schemes and algorithms, LOOFS is expected to generate a more accurate model output than the former LOOFS, whose model core was the Princeton Ocean Model (POM).

The NWS and NOS work together to run LOOFS operationally on NOAA's High Performance Computing System (HPCS). By running on NOAA's HPCS, LOOFS has direct access to National Weather Service operational meteorological products that are required for reliable operations.

Disclaimer
The Lake Ontario Operational Forecast System (LOOFS) has been implemented by NOAA's National Ocean Service (NOS) to provide the maritime user community with short-term predictions of water levels, water currents, and water temperatures of the Lake Ontario. LOOFS uses a numerical hydrodynamic model to generate the nowcast and forecast information; therefore, they should be considered as model-generated nowcast and forecast guidance.
