Once again, the low-level circulation of the depression has 
separated from the deep convection, which is located over 50 miles 
to the east-northeast of the center.  Subjective satellite intensity 
estimates have held steady and the initial intensity remains at 30 
kt.  The already strong west-southwesterly vertical wind shear is 
forecast to increase further in the next day or so and will likely 
cause the cyclone to weaken quickly.  Most of the global models 
suggest the system will open into a trough within a day or two.  The 
official forecast now shows the depression becoming a post-tropical 
remnant low in 12 hours and dissipated by 36 hours.

The depression is moving west-northwestward at about 11 kt.  This 
general motion is expected to continue for the next day or so while 
the system follows the low-level flow around a ridge to the north.  
The NHC track forecast has shifted south from the previous forecast 
possibly due to the more westward initial position and is on the 
northern edge of the guidance envelope.
