DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Tropical Storm Gonzalo was
located near latitude 10.0 North, longitude 55.6 West. Gonzalo is
moving toward the west near 18 mph (30 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 Saturday afternoon or evening and over the eastern
Caribbean Sea on Sunday.
 
Data from an Air Force Reserve Hurricane Hunter aircraft
indicate that Gonzalo's maximum sustained winds have decreased
to near 40 mph (65 km/h) with higher gusts. Some slight
strengthening is possible 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
early next week.
 
Data from the Hurricane Hunter plane indicate that
tropical-storm-force winds extend outward up to 25 miles (35 km)
from the center.
 
The estimated minimum central pressure is 1008 mb (29.77 inches).
