Tropical Depression Eleven Discussion Number   2
NWS National Hurricane Center Miami FL       AL112023
500 PM AST Tue Aug 29 2023
 
The center of the depression is exposed this afternoon. Its 
associated convection remains displaced over the eastern portion of 
the circulation by westerly shear. Since the satellite presentation 
has not improved since the earlier ASCAT retrievals, the initial 
intensity remains 30 kt for this advisory.

Visible and microwave images indicate the depression has moved 
little since this morning, and it appears to be currently drifting 
north-northwestward at 345/2 kt within weak steering currents. A 
ridge to the north of the depression is forecast to slide eastward 
through midweek, which should allow the cyclone to gradually turn 
northward and north-northeastward as it accelerates within 
deepening southerly flow ahead of Hurricane Franklin. The updated 
NHC track forecast has been adjusted slightly westward in agreement 
within the latest multi-model consensus aids.

There is a brief window during the next day or so where the models 
suggest the shear could decrease enough to allow the depression to 
strengthen into a tropical storm. Afterwards, upper-level outflow 
from Franklin will likely strip away its convection and inhibit any 
further intensification. The depression is forecast to become 
post-tropical shortly before it becomes absorbed in about 72 h by 
the broader circulation associated with Franklin.
