WIND:  Tropical storm conditions are expected to diminish within
the tropical storm warning areas later this morning.
 
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 through 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 begin subsiding
along the Lesser Antilles through the day.  Swells are likely
to increase in areas adjacent to the central Caribbean Sea
later today and on Sunday.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
