DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Tropical Storm Dorian was
located by data from an Air Force Reserve reconnaissance aircraft
and the Martinique radar near latitude 14.2 North, longitude 61.8
West.  Dorian is moving toward the west-northwest near 13 mph (20
km/h), and this motion is expected to continue through tonight,
followed by a turn toward the northwest on Wednesday.  On the
forecast track, the center of Dorian will move across the eastern
and northeastern Caribbean Sea during the next few days, passing
near or south of Puerto Rico on Wednesday, move near or over eastern
Hispaniola Wednesday night, and move north of Hispaniola on
Thursday. On Thursday night and Friday, the center of Dorian is
forecast to move near the Turks and Caicos and southeastern
Bahamas.

Maximum sustained winds remain near 50 mph (85 km/h) with higher
gusts. Slow strengthening is forecast during the next 48 hours, and
Dorian is forecast to be near hurricane strength when it moves close
to Puerto Rico and eastern Hispaniola.

Tropical-storm-force winds extend outward up to 45 miles (75 km)
from the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Dorian is expected to produce the following rain
accumulations through Thursday:

Martinique to Saint Vincent...3 to 6 inches, isolated 10 inches.
Grenadines to Grenada...1 to 3 inches.
Guadeloupe to Dominica...1 to 4 inches.
Puerto Rico and Dominican Republic...4 to 6 inches, isolated 8
inches.
U.S. Virgin Islands...1 to 3 inches, isolated 4 inches.

This rainfall may cause life-threatening flash floods.

WIND:  Tropical storm conditions are occurring in portions of the
tropical storm warning area in the Lesser Antilles and these
conditions are expected to subside later today. Tropical
storm conditions are expected and hurricane conditions are possible
in Puerto Rico on Wednesday and in portions of the Dominican
Republic late Wednesday and Thursday.

SURF:  Swells generated by Dorian are affecting portions of the
Lesser Antilles and they should continue during the next several
hours.  Swells are expected to increase along the southern coasts
of Puerto Rico and Hispaniola on Wednesday and they could cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
