Critical Update on reduced HWRF v4.0a capabilities

The Hurricane WRF v4.0a public release will have reduced capabilities due to format and library changes impacting input datasets. Starting in January 2021, an update was made to the bufrlib version, impacting input data for data assimilation. Additionally, when GFSv16 becomes operational (expected March 2021), output will be in NetCDF format, which is not supported in HWRFv4.0a. Only use of GRIB2 data will be supported. Implications of these changes are that HWRFv4.0a cannot run with data assimilation or vortex initialization. Historical cases may still be run using legacy input data formats.
