6.3.1.1. Met Fast

Met Fast group is a pre-configured set of wind, pressure and precipitation data at 1 degree of spatial resolution.We use the most recent upgrade of the GFS model, the FV3, as the basis of this Met section. The FV3 increased the power and resolution of the GFS, most recently it correctly predicting the path of category 4 Hurricane Laura over southwestern Louisiana in August 2020 when other well-known models were sending it elsewhere.

 

Use the Met Fast section to get a quick assessment of impending weather anywhere from 1 to 7 days out (with 4 frames per day) and especially if you will be retrieving weather data over low bandwidth satellite connections. Data updates on the half-hour at approximately 5, 11, 17 and 2300 UTC.

 

If you see a weather event in the Met Fast data at which you want a closer look, then move to Met High to get a closer look...
