DISCUSSION AND OUTLOOK
----------------------
At 200 AM AST (0600 UTC), the center of Tropical Storm Gonzalo was
located near latitude 10.0 North, longitude 57.8 West.  Gonzalo is
moving toward the west near 17 mph (28 km/h).  A general westward to
west-northwestward motion is expected for the next couple of days.
On the forecast track, Gonzalo will move across the southern
Windward Islands this afternoon or evening and over the eastern
Caribbean Sea on Sunday.
 
Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts.  Little change in strength is expected before Gonzalo reaches
the southern Windward Islands.  Weakening is expected after Gonzalo
moves over the eastern Caribbean Sea, and the system is forecast to
dissipate by Sunday night or Monday.
 
Data from the Hurricane Hunter plane indicate that the 
tropical-storm-force winds extend outward up to 25 miles (35 km)
from the center.

The estimated minimum central pressure based on data from the Air 
Force Reserve Hurricane Hunters is 1009 mb (29.80 inches).
