HFIP GFS/EnKF Forecast Graphics
Administration (NOAA) National Center for Environmental Prediction (NCEP) Global Forecast
System (GFS) model, initialized with an experimental hybrid variational/Ensemble Kalman Filter (EnKF)
data assimilation system.
The data assimilation system utilizes an 80 member ensemble (run at T574 resolution) to initialize a T1148
control forecast using the hybrid variational/EnKF system. 20 T574 ensemble members are run out to 7 days,
along with a single T1148 control forecast 4 times daily (at 0000, 0600, 1200, and 1800 UTC). These
experimental forecasts are made possible by support from the NOAA Hurricane Forecast Improvement Program (HFIP).
WARNING: These forecast are experimental and not intended to replace the official
forecasts issued by the National Hurricane Center and/or the National Weather Service.
