MFP is not a standalone modeling application; it is a part of the CWMS CAVI created to prepare the HMS meteorologic model for use in a forecast by combining observed data with forecast data and associating that data with the met model (Precip Alternative). 

Although most of your MFP alternatives from your CWMS 3.2.2 watershed should migrate to CWMS 3.2.3 without a problem, some alternatives may encounter one or more of the following issues. 

  • If a misalignment occurs with table data in the MFP alternative editor, resizing the table columns and/or the MFP Alternative Editor window will re-align the columns.
  • MFP is having trouble with manual forecast temperature. Please use gridded temperature grids.  If you need to use manual forecast temperature and have issues, please contact HEC.

MFP is only compatible with HEC-HMS's basin model's file-specified (mod file or grid cell file) method.  MFP is not compatible with the new HEC-HMS Non-structured or Unstructured basin Discretization methods, for which case HEC-MetVue should be used instead of MFP.
