DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Tropical Storm Dorian was
located near latitude 16.0 North, longitude 63.0 West.  Dorian is
moving toward the northwest near 13 mph (20 km/h), and this general
motion is expected to continue through Thursday.  On the forecast
track, the center of Dorian will move across the northeastern
Caribbean Sea overnight, pass over or near Puerto Rico on Wednesday,
and move near or just east of eastern Hispaniola Wednesday night.
Dorian is forecast to move near or to the east of the Turks and
Caicos and the southeastern Bahamas on Thursday night, and near or
to the east of the central Bahamas on Friday.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Slow strengthening is forecast during the next 24 hours, and
Dorian is forecast to be near hurricane strength when it approaches
Puerto Rico on Wednesday.  Some weakening is expected after Dorian
moves across the higher terrain of Puerto Rico.  Dorian is expected
to gradually re-strengthen on Thursday and Friday while passing near
or to the east of the Turks and Caicos and southeastern and central
Bahamas.

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

The minimum central pressure reported by the Hurricane Hunter
aircraft is 1006 mb (29.71 inches).
