DISCUSSION AND OUTLOOK
----------------------
At 800 PM AST (0000 UTC), based on data from the Barbados radar 
and surface observations the disturbance was centered near latitude
10.4 North, longitude 61.0 West. The system is moving toward the
west near 25 mph (40 km/h).  A westward or west-northwestward motion
is expected through Thursday.  On the forecast track, the system
will pass near or over portions of the southern Windward Islands
tonight, and move over the southern Caribbean Sea or near the
northern coast of Venezuela and the northeast coast of Colombia on
Wednesday and Thursday.

Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. Some strengthening is forecast during the next few days if
the disturbance remains over water.

Conditions appear conducive for development if the disturbance
remains over water, and it will likely become a tropical storm near
the southern Windward Islands or while moving westward across the
southern Caribbean Sea.
* Formation chance through 48 hours...high ...70 percent.
* Formation chance through 5 days...high...90 percent.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.  During the past several hours, there was a wind 
gust of 74 mph (119 km/h) on Grenada during a severe thunderstorm. 
There have also been other reports of wind gust of tropical-storm 
force elsewhere across portions of the southern Windward Islands 
and Trinidad and Tobago.
