DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Tropical Storm Dorian was
located near latitude 12.3 North, longitude 57.7 West. Dorian is
moving toward the west-northwest near 14 mph (22 km/h) and this
motion is expected to continue through Tuesday night, followed by a
turn toward the northwest on Wednesday. On the forecast track, the
center of Dorian is expected to be near the Windward Islands late
today and tonight, and move into the eastern Caribbean Sea on
Tuesday. Dorian is expected to pass near or south of Puerto Rico on
Wednesday and approach eastern Hispaniola Wednesday night.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Some strengthening is forecast during the next few days, and Dorian
could be near hurricane strength when it passes through the northern
Windward Islands on Tuesday, and is expected to be a hurricane when
it moves near Puerto Rico and eastern Hispaniola.

Dorian is a small tropical cyclone. Tropical-storm-force winds
only extend outward up to 45 miles (75 km) from the center.

The estimated minimum central pressure is 1002 mb (29.59 inches).


HAZARDS AFFECTING LAND
----------------------
Rainfall:  Dorian is expected to produce total rain accumulations of
3 to 8 inches in the Windward Islands from Martinique south to St.
Vincent, including Barbados.  Isolated maximum totals of 10 inches
are possible across the northern Windward Islands.  Rainfall totals
of 1 to 3 inches are expected from the Grenadines, south to Grenada
and across Dominica.

WIND:  Hurricane conditions are possible tonight and early Tuesday
within the Hurricane Watch area in the Lesser Antilles.  Tropical
storm conditions are likely in the warning area by late today.
Tropical storm conditions are possible within the tropical
storm watch area by tonight or Tuesday.

SURF:  Swells generated by Dorian will be affecting portions of the
Lesser Antilles by late today. These swells could cause life-
threatening surf and rip current conditions.  Please consult
products from your local weather office.
