Download Agenda


The primary objective of this meeting was to discuss the key HFIP strategies as documented in the HFIP Strategic plans including development of the next generation Hurricane Analysis and Forecast System (HAFS) within UFS. The current state of operational hurricane modeling capabilities and challenges, forecasters' needs and activities supporting operations as well as the results and accomplishments from the 2020 hurricane season will be discussed.


  • Day 1 (Nov 17): Programmatic Updates; Forecaster needs and activities supporting operations.
  • Day 2 (Nov 18): Updates from Current Operational Forecast; HFIP Stream 2 results; Special storm session.
  • Day 3 (Nov 19): HFIP Supported External Research; HAFS Development and Computations.
