Lake Michigan Operational Forecast System (LMOFS)

Notice: A new FVCOM-based Lake Michigan and Huron Operational Forecast System (LMHOFS) is becoming operational on 07/23/2019 18:00 (EST). By combining Lake Michigan and Lake Huron into one model grid with higher horizontal resolution, LMHOFS is expected to provide more accurate information than the presnet LMOFS. The information about LMHOFS, its products and graphics will be available at https://tidesandcurrents.noaa.gov/ofs/lmhofs/lmhofs.html. The POM-based LMOFS will retire and its model output on the Thredds server will no longer be available after 2019/07/23 18:00 (EST). For more information on the upgrade, please refer to the Science Change Notice.

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 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. GLOFS nowcast and forecast guidance will provide an increased margin of safety and maximize the efficiency of commerce throughout the Lakes. For more information, please click here.

Nature of GLOFS Products
The Great Lakes Operational Forecast System (GLOFS) has been implemented by NOAA's National Ocean Service (NOS) to provide the maritime community with improved short-term predictions of water levels, water currents and water temperatures of the Great Lakes. GLOFS uses a numerical hydrodynamic model to generate these predictions. Therefore, these predictions should be considered as computer-generated nowcast and forecast guidance. For more detailed information related to the OFS disclaimer, please visit at the Disclaimers web page.
