A new FVCOM-based Lake Michigan and Huron Operational Forecast System (LMHOFS) is operational since 07/23/2019. 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 previous LHOFS. The information about LMHOFS, its products and graphics will be available at https://tidesandcurrents.noaa.gov/ofs/lmhofs/lmhofs.html. The POM-based LHOFS has retired and its model output on the Thredds server is no longer available.
