HFIP GFS/EnKF Forecast Graphics



This page provides access to ensemble forecasts using the National Oceanic and Atmospheric
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 T382 resolution) to initialize a T878
control forecast using the hybrid variational/EnKF system. 20 T382 ensemble members are run out to 5 days,
along with a single T878 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.
