The GFDL Hurricane Model text product is being discontinued

because the GFDL hurricane model is being discontinued.


Please see Service Change Notice 17-45 for details:


The Beta Advection (BAM) and Limited Barotropic (LBAR) tropical

cyclone track models included in the latter two products are

also being discontinued. The BAM models are not being

transitioned to the Weather and Climate Operational

Supercomputing System (WCOSS) and the LBAR model is obsolete. 

These changes eliminate all of the track model guidance included

in the Tropical Cyclone Guidance Message products, leaving only

the Statistical Hurricane Intensity Prediction Scheme

(SHIPS)model output. With only the SHIPS model output left, the

Tropical Cyclone Guidance Message products will be discontinued. 


Users can access a comprehensive real-time database of tropical

cyclone guidance models, which includes the SHIPS model and
