The system has not become significantly better organized since 
becoming a tropical cyclone earlier today.  A small area of deep 
convection has been persisting near and just west of the center of 
circulation, but convective banding features are limited at this 
time.  Cirrus cloud motions show fairly well-defined upper-level 
anticyclonic flow over the area.  The current intensity estimate is 
held at 25 kt based on a Dvorak classification of T1.5 from TAFB, an 
ADT estimate from CIMSS, and OSCAT data.

Center fixes indicate a slow, but generally northwestward, motion at 
around 310/3 kt.  A mid-level ridge to the northeast of the system 
should cause a northwestward to west-northwestward movement at a 
slightly faster forward speed during the next few days.  A westward 
to southwestward turn is forecast in 3-5 days in response to a 
slight building of the ridge to the northwest.  The official track 
forecast is quite similar to that from the previous advisory, and in 
good agreement with the corrected consensus model guidance, HCCA.

Given the seemingly favorable upper-level winds and warm SSTs, some 
strengthening is predicted.  However, since the cyclone is embedded 
in an elongated convergence zone, this could impede significant 
intensification.  The official forecast shows modest strengthening 
over the next couple of days which is in general agreement with HCCA 
and the HAFS regional hurricane models.  Later in the forecast 
period, increasing vertical wind shear associated with 
south-southwesterly flow ahead of a large upper-level trough should 
lead to weakening.
