DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Tropical Storm Bret was
located near latitude 13.0 North, longitude 52.5 West.  Bret is
moving toward the west near 14 mph (22 km/h), and this general 
motion with an increase in forward speed is expected during the next 
several days.  On the forecast track, the center of Bret is 
expected to approach the Lesser Antilles on Thursday, move across 
the Lesser Antilles late Thursday and Thursday night, and then move 
westward across the eastern and central Caribbean Sea Friday and 
Saturday.
 
Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Some increase in strength is forecast before Bret reaches the 
Lesser Antilles.  Weakening is expected by Friday once Bret moves 
over the Caribbean Sea, and the system is likely to dissipate on 
Saturday. 
 
Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.
 
The estimated minimum central pressure is 1001 mb (29.56 inches).

inches with maximum amounts of 10 inches are possible across
portions of the Lesser Antilles from Guadeloupe south to St. Vincent
and the Grenadines, including Barbados.  The heavy rainfall could
