The system continues to produce vigorous deep convection and also
exhibits some banding features.  However, reports from an Air Force
Hurricane Hunter aircraft indicate that there is no well-defined
center of circulation at this time.  A NOAA Hurricane Hunter 
aircraft is scheduled to investigate the system again this 
afternoon.

The system is expected to remain in a low-shear and moderately moist 
atmospheric environment for the next couple of days.  However, 
interaction with land and fast forward motion will likely limit 
intensification until the system reaches the southwestern Caribbean 
Sea later this week.  More significant strengthening, possibly into 
a hurricane, could occur over the latter area.

Although the center position is not precise, the initial motion 
estimate is kept the same, or 280/20 kt.  A strong mid-tropospheric 
ridge is likely to remain anchored to the north of the system this 
week.  Therefore a continued westward to west-northwestward motion 
is expected through the forecast period.  The official forecast 
track is mostly unchanged and remains close to the corrected 
dynamical model consensus.


KEY MESSAGES:

1.  Heavy rainfall is expected across the Windward Islands and
northeastern Venezuela tonight through Wednesday. Localized flash
flooding will be possible.

2.  Winds to tropical-storm-force are expected over portions of the
southern Windward Islands tonight, over Islas Margarita Wednesday 
morning, and over the ABC Islands by Wednesday evening.  Tropical 
storm conditions are possible along the northeastern coast of 
Venezuela tonight and Wednesday evening.

3.  There is higher-than-normal uncertainty in the system's forecast 
intensity once it reaches the southwestern Caribbean Sea late 
Thursday and Friday, which will depend on how much it interacts with 
land from tonight through Thursday.
