DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Tropical Storm Dorian was
located near latitude 17.5 North, longitude 64.5 West. Dorian is
moving toward the northwest near 13 mph (20 km/h), and this motion
is expected to continue for the next day or two. On this track,
Dorian should move near the U.S. and British Virgin Islands and
then continue over the open Atlantic well east of the southeastern
Bahamas.

Maximum sustained winds have increased to near 70 mph (110 km/h)
with higher gusts.  Dorian is forecast to become a hurricane later
today and continue strengthening during the next few days over the
Atlantic waters.

Tropical-storm-force winds extend outward up to 80 miles (130 km)
primarily to the east of the center.

An Air Force plane just estimated a minimum central pressure of
999 mb (29.50 inches).


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

Northern Leeward Islands...1 to 3 inches.
Eastern Puerto Rico, the Virgin Islands, and the northwest
Bahamas...4 to 6 inches, isolated 10 inches
Western Puerto Rico and the central Bahamas...2 to 4 inches
Coastal sections of the Southeast United States...4 to 8 inches,
isolated 10 inches.

This rainfall may cause life-threatening flash floods.

WIND:  Hurricane conditions are expected over Vieques, Culebra, and
the U.S. and British Virgin Islands today.  Tropical storm
conditions are expected in Puerto Rico this afternoon and tonight.
Tropical storm conditions are still possible in portions of the
Dominican Republic tonight and Thursday but are becoming less likely
to occur.

Wind speeds atop and on the windward sides of hills and mountains
are often up to 30 percent stronger than the near-surface winds
indicated in this advisory, and in some elevated locations could be
even greater.

SURF:   Swells are expected to increase later today 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.
