area on Friday.


DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Hurricane Dorian was located
near latitude 22.5 North, longitude 67.7 West. Dorian is moving
toward the northwest near 13 mph (20 km/h), and this general
motion is expected to continue through Friday.  A west-northwestward
to westward motion is forecast to begin by Friday night and continue
into the weekend.  On this track, Dorian should move over the
Atlantic well east of the southeastern and central Bahamas tonight
and on Friday, approach the northwestern Bahamas Saturday, and move
near or over portions of the northwest Bahamas on Sunday.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts.  Strengthening is forecast during the next few days, and
Dorian is expected to become a major hurricane on Friday, and
remain an extremely dangerous hurricane through the weekend.

Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 90 miles
(150 km).

The estimated minimum central pressure is 986 mb (29.12 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Dorian is expected to produce the following rainfall
accumulations this weekend into early next week:

The central Bahamas...1 to 2 inches, isolated 4 inches.
The northwestern Bahamas...3 to 5 inches, isolated 7 inches.
Coastal sections of the Southeast United States...5 to 10 inches,
isolated 15 inches.

This rainfall may cause life-threatening flash floods.

SURF:  Swells around the U.S. and British Virgin Islands and
Puerto Rico should gradually diminish today.  Swells are likely to
begin affecting the east-facing shores of the Bahamas and the
southeastern United States coast during the next few days.  These
swells are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
