A Hurricane Watch means that hurricane conditions are possible

the anticipated first occurrence of tropical-storm-force winds,
conditions that make outside preparations difficult or dangerous.

Interests in southern and central Florida should monitor the
progress of Dorian.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the eye of Hurricane Dorian was located
near latitude 24.5 North, longitude 69.8 West. Dorian is moving
toward the northwest near 10 mph (17 km/h). A slower west-
northwestward to westward motion should begin tonight and continue
into early next week.  On this track, the core of Dorian should
move over the Atlantic well north of the southeastern and central
Bahamas today and tomorrow, be near or over the northwestern
Bahamas on Sunday, and be near the Florida peninsula late Monday.

Maximum sustained winds are near 110 mph (175 km/h) with higher
gusts.  Dorian is expected to become a major hurricane later
today, and it will remain an extremely dangerous major hurricane
while it moves near the northwestern Bahamas and approaches the
Florida peninsula into early next week.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 105 miles
(165 km).

The estimated minimum central pressure from the NOAA and Air Force
reconnaissance planes is 972 mb (28.71 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are possible in the northwestern
Bahamas by Sunday, with tropical storm conditions possible by
Saturday night or Sunday morning.

STORM SURGE:  A life-threatening storm surge will raise water levels
by as much as 10 to 15 feet above normal tide levels in areas of
onshore winds in the northwestern Bahamas. Near the coast,the surge
will be accompanied by large and destructive waves.

RAINFALL:  Dorian is expected to produce the following rainfall
accumulations this weekend into the middle of next week:

Northwestern Bahamas and coastal sections of the Southeast
United States...6 to 12 inches, isolated 18 inches.
Central Bahamas...1 to 2 inches, isolated 4 inches.

This rainfall may cause life-threatening flash floods.

SURF:  Swells are likely to begin affecting the east-facing shores
of the Bahamas, the Florida east coast, 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.
