DISCUSSION AND OUTLOOK

gusts. Gradual weakening is anticipated over the next couple of
days, and the system is likely to dissipate over the central
Caribbean Sea on Sunday.
At 800 PM AST (0000 UTC), the center of Tropical Storm Bret was
located near latitude 13.4 North, longitude 60.3 West. Bret is
moving toward the west near 16 mph (26 km/h) and this general motion with an increase in forward speed is expected during the next few days. On the forecast track, the center of Bret is expected to move across the Windward Islands during the next several hours, and then
move westward across the eastern and central Caribbean Sea Friday and Saturday.
Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center. Several automated stations on Martinique have
recently reported sustained winds of 40-45 mph (65-70 km/h) and
wind gusts of 50-60 mph (85-95 km/h).
The estimated minimum central pressure is 1004 mb (29.65 inches).

RAINFALL: Storm total rainfall amounts of 3 to 6 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 lead to
flash flooding, especially across areas of higher terrain. Urban
flooding is also possible.
SURF: Swells generated by Bret are expected to affect portions of
the Lesser Antilles through Friday. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
