A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area. Preparations to protect life and
property should be rushed to completion.

A Hurricane Watch means that hurricane conditions are possible
within the watch area.  A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

A Tropical Storm Warning means that tropical storm conditions are
expected within the warning area within 36 hours.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests elsewhere along the east coast of Florida should continue

warnings may be required later today.

For storm information specific to your area in the United States,
including possible inland watches and warnings, please monitor
products issued by your local National Weather Service forecast
office. For storm information specific to your area outside of the

DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the extremely distinct eye of Hurricane
Dorian was located near latitude 26.5 North, longitude 77.1 West.
Dorian is moving toward the west near 7 mph (11 km/h). A slower
westward motion should continue for the next day or two, followed by
a gradual turn toward the northwest.  On this track, the core of
extremely dangerous Hurricane Dorian will continue to pound Great
Abaco today and the move near or over Grand Bahama Island tonight
and Monday. The hurricane should move closer to the Florida east
coast late Monday through Tuesday night.

Maximum sustained winds are near 185 mph (295 km/h) with higher
gusts.  Dorian is a extremely dangerous category 5 hurricane on the
Saffir-Simpson Hurricane Wind Scale.  Some fluctuations in intensity
are likely, and Dorian is expected to remain a catastrophic
hurricane during the next few days.

Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 140
miles (220 km).

The minimum central pressure measured by both NOAA and Air Force
reconnaissance plane was 911 mb (26.90 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Catastrophic hurricane conditions are occurring in the Abacos
Islands and will spread across Grand Bahama Island later today and
tonight. Do not venture out into the eye, as winds will suddenly
increase as the eye passes.

Hurricane conditions are possible within the hurricane watch area in
Florida by late Monday or early Tuesday.

Tropical storm conditions are expected within the tropical storm
warning area on Monday and Tuesday.

Tropical storm conditions are possible within the tropical storm
watch area by Monday night.

STORM SURGE:  A life-threatening storm surge will raise water levels
by as much as 18 to 23 feet above normal tide levels in areas of
onshore winds on the Abaco Islands and Grand Bahama Island.  Near
the coast, the surge will be accompanied by large and destructive
waves.

The combination of a dangerous storm surge and the tide will cause
normally dry areas near the coast to be flooded by rising waters
moving inland from the shoreline. The water could reach the
following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Volusia/Brevard County Line to Jupiter Inlet FL...4 to 7 ft
North of Deerfield Beach to Jupiter Inlet FL...2 to 4 ft

The surge will be accompanied by large and destructive waves.
Surge-related flooding depends on the how close the center of
Dorian comes to the Florida east coast, and can vary greatly over
short distances.  For information specific to your area, please see
products issued by your local National Weather Service forecast
office.

RAINFALL:  Dorian is expected to produce the following rainfall
totals through late this week:

Northwestern Bahamas...12 to 24 inches, isolated 30 inches.
Coastal Carolinas...5 to 10 inches, isolated 15 inches.
Central Bahamas and the Atlantic Coast from the Florida peninsula
through Georgia...2 to 4 inches, isolated 6 inches.

This rainfall may cause life-threatening flash floods.

SURF:  Large swells are already affecting east-facing shores of the
Bahamas, the Florida east coast, and will spread northward along 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.
