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).
The first dynamical hurricane track forecast model, the Sanders Barotropic Tropical Cyclone Track Prediction Model (SANBAR), [9] was introduced in 1970 and was used by the National Hurricane Center as part of its operational track guidance through 1989. It was based on a simplified set of atmospheric dynamical equations (the equivalent ...

Helene is the fifth hurricane of the 2024 Atlantic season. By late Thursday it will be make it the fifth consecutive year that a major hurricane hits the U.S. mainland, according to Colorado State ...
Ahead of the 2003 Pacific hurricane season, the NOAA forecasters decided to start issuing an experimental tropical cyclone outlook for the Eastern Pacific, which was designed not to be updated during the mid-season. [5] As a result of both the 2003 and 2004 outlooks being successful, the predictions became an operational product during 2005. [6]
