Visible and infrared satellite imagery depicts that showers and 
thunderstorms have become better organized around a well-defined 
low-level center associated with the low pressure area (AL96) that 
NHC has been tracking the past few days. Subjective satellite 
Dvorak intensity estimates from TAFB and SAB were both T2.0/30 kt. 
Given the better defined low-level center and these satellite 
estimates, advisories are being initiated on Tropical Depression 
Fourteen over the far eastern Atlantic, with an initial intensity
of 30 kt. 

The depression is moving generally west-northwest and this 
motion is forecast to continue over the next few days, with a 
decrease in forward speed and a turn to the north at the end of the 
forecast period, into a weakness in the tropical ridge. The 
guidance envelope is in fairly good agreement and the NHC track 
forecast lies between the HCCA and TVCA consensus aids.

Tropical Depression Fourteen is forecast to be over warm sea surface 
temperatures near 28-29 degrees Celsius during the next several 
days. However, the depression will encounter some northerly vertical 
wind shear, and drier mid-level relative humidities along the 
current forecast track. Given the mixed environmental conditions the 
NHC forecast calls for gradual strengthening during the early part 
of the forecast but brings the system to hurricane strength before 
the end of the period. The NHC intensity forecast lies near the HCCA 
and IVCN intensity consensus aids.
