NOAA launches new hurricane forecast model as Atlantic season starts strong

06/27/2023: HAFS Initial Operational Capability Implementation

HAFSv1 (including both HFSA and HFSB configurations) was implemented into NOAA/NWS/NCEP operations starting with the 12Z forecast cycle today (06/27/2023). Details about the HAFSv1 implementation can be found in this link. And the corresponding NWS Service Change Notice can be seen here.

Correspondingly, the current HWRF and HMON systems will continue running operationally for the 2023 hurricane season and are currently scheduled to be decommissioned on or about November 30, 2023. The legacy models will run a maximum of three storms at one time and the output will be delayed on average of 30 minutes compared to HAFS.
