Tropical Storm Joyce Discussion Number  14

Joyce is a highly sheared cyclone with the low-level center well
separated from the convection.  Given the deterioration of the cloud
pattern, the initial intensity has been generously set at 35 kt.
The shear is expected to remain belligerently high and the ocean
along the forecast track is cooler. On this basis, the NHC forecast
calls for additional weakening, and then dissipation beyond 3 days
if not sooner.

Joyce continues to move eastward at about 15 kt embedded within the
fast mid-latitude flow.  The system should decrease its forward
speed as it weakens and become a shallow cyclone.  It should
then turn east-southeast and even southward steered by the low-level
