The GFS was the most skillful single track model for the 2021 Atlantic hurricane season at all lead times, and its ensembles are much improved relative to previous iterations.
An example of a forecast product from the GFS, in this case a 96-hour forecast of 850 mb geopotential height and temperature. The Global Forecast System (GFS) is a global numerical weather prediction system containing a global computer model and variational analysis run by the United States' National Weather Service (NWS).
2024 WEATHERTIGER MODEL RANKINGS. Building on validation data from the 2023 season NHC Forecast Verification Report, here’s a rundown of the computer model guidance available for hurricanes, in ...
Trackwise, the GUNA model is a consensus of the interpolated versions of the GFDL, UKMET with quality control applied to the cyclone tracker, United States Navy NOGAPS, and GFS models. The version of the GUNA corrected for model biases is known as the CGUN. The TCON consensus is the GUNA consensus plus the Hurricane WRF model.
At the time of Erika's classification, forecast models diverged significantly on the potential future of the storm. Statistical guidance and the HWRF depicted a hurricane while the ECMWF and GFS showed a weaker system due to increasing wind shear. The models that intensified the storm indicated a more northerly track while those that kept it ...
Seven other years on record have had eight or more named storms by Aug. 21: 1936, 2005, 2011, 2012, 2017, 2020 and 2021, according to Philip Klotzbach, Colorado State University meteorologist ...

Multiple computer models that project possible storm paths suggest that invest 98 could develop into the next tropical storm of the season and head west into the Caribbean Sea.
