HAFS Enters Operations

Hurricane Analysis and Forecast System (HAFS)

A major component of the Hurricane Forecast Improvement Program (HFIP) response to Section 104 of the Weather Research Forecasting Innovation Act of 2017 (Wx Act) was to progress and operationalize an advanced numerical prediction based hurricane model. On June 27, 2023 the Hurricane Analysis and Forecasting System (HAFS) entered operational status on the National Oceanic and Atmospheric Administration (NOAA), National Weather Service (NWS), National Centers for Environmental Prediction (NCEP) Weather and Climate Operational Supercomputing System 2 (WCOSS2). The HAFS model is NOAA’s next generation hurricane forecast model which builds on the world class multiple moving nest skills developed by HFIP utilizing the Hurricane Weather Research and Forecasting (HWRF) model.
