DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the center of Tropical Storm Dorian was
located near latitude 17.1 North, longitude 64.1 West. Dorian is
moving toward the northwest near 13 mph (20 km/h), and this general
motion is expected to continue during the next few days.  On the
forecast track, the center of Dorian will pass over or near the U.S.
and British Virgin Islands and Puerto Rico later today.  Dorian is
then forecast to move to the east of the Turks and Caicos and the
southeastern Bahamas on Thursday, and near or to the east of the
central and northwestern Bahamas on Friday and Saturday.

Maximum sustained winds are near 60 mph (95 km/h) with higher
gusts. Some strengthening is expected today, and Dorian is forecast
to be near hurricane strength when it approaches the Virgin Islands
and Puerto Rico.  Although weakening is possible after Dorian moves
across Puerto Rico and the Virgin Islands, the storm is forecast to
strengthen late this week and this weekend while passing near or to
the east of the Turks and Caicos and the Bahamas.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center. A wind gust to near 39 mph (63 km/h) was recently
reported at St. Thomas in the U.S. Virgin Islands.

An Air Force reconnaissance plane just reported an estimated
minimum central pressure of 1003 mb (29.62 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Dorian is expected to produce the following rainfall
accumulations:

Western Leeward Islands from Guadeloupe to St. Kitts to Anguilla...1
to 4 inches.
Southern and Eastern Puerto Rico and the U.S. and British Virgin
Islands...4 to 6 inches, isolated 10 inches.
Northwestern Puerto Rico...1 to 4 inches.
Haiti and Dominican Republic...1 to 3 inches
Southern Bahamas...1 to 4 inches.
Northern Bahamas...3 to 6 inches.
Florida Peninsula...4 to 8 inches, isolated 10 inches.

This rainfall may cause life-threatening flash floods.

WIND:  Tropical storm conditions are expected and hurricane
conditions are possible in Puerto Rico, Vieques, Culebra, and
the U.S. Virgin Islands today.  Tropical storm conditions are
expected in the British Virgin Islands today.  Tropical storm
conditions are still possible in portions of the Dominican Republic
tonight and Thursday.

SURF:  Swells generated by Dorian are gradually subsiding in the
Lesser Antilles.  Swells are expected to increase later this morning
across the U.S. and British Virgin Islands and along the southern
coasts of Puerto Rico and Hispaniola, and they could cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
