DISCUSSION AND OUTLOOK
At 200 AM EDT (0600 UTC), the eye of Hurricane Dorian was located
near latitude 26.9 North, longitude 78.4 West. Dorian is stationary
just north of Grand Bahama Island. A slow northwestward motion is
expected to occur early today. A turn toward the north-northwest is
forecast by this evening, with a turn to the north forecast by
Wednesday, followed by a turn to the northeast on Thursday. On this
track, the core of extremely dangerous Hurricane Dorian will
continue to pound Grand Bahama Island today. The hurricane will
then move dangerously close to the Florida east coast late today
through Wednesday evening, very near the Georgia and South Carolina
coasts Wednesday night and Thursday, and near or over the North
Carolina coast late Thursday.
Maximum sustained winds are near 120 mph (195 km/h) with higher
gusts. Dorian is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Although gradual weakening is forecast,
Dorian is expected to remain a powerful hurricane during the next
couple of days.
Hurricane-force winds extend outward up to 45 miles (75 km) from
the center, and tropical-storm-force winds extend outward up to 150
miles (240 km). Settlement Point, Grand Bahama, recently reported a
sustained wind of 63 mph (102 km/h) with a gust to 89 mph (143
km/h), and Juno Beach Pier in northern Palm Beach County, Florida,
recently reported a sustained wind of 49 mph (80 km/h) with a gust
to 60 mph (96 km/h).
The estimated minimum central pressure is 950 mb (28.05 inches).
HAZARDS AFFECTING LAND
WIND: Devastating hurricane conditions continue on Grand Bahama
Hurricane conditions are expected within the Hurricane Warning area
in Florida by this evening. Hurricane conditions are possible in
the Hurricane Watch area beginning Wednesday.
Tropical storm conditions are expected within the Tropical Storm
warning area through today, and are possible in the Tropical
Storm watch area through this 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 on Grand Bahama Island. Near the coast, the surge
will be accompanied by large and destructive waves. Water levels
should very slowly subside on the Abaco Islands today.
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...
Lantana FL to South Santee River SC...4 to 7 ft
North of Deerfield Beach FL to Lantana FL...2 to 4 ft
Water levels could begin to rise well in advance of the arrival of
strong winds. 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 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
RAINFALL: Dorian is expected to produce the following rainfall
totals through late this week:
Northwestern Bahamas...Additional 6 to 12 inches, isolated storm
totals of 30 inches.
Central Bahamas...Additional 1 to 3 inches, isolated storm totals
of 6 inches.
Coastal Carolinas...5 to 10 inches, isolated 15 inches.
Atlantic Coast from the Florida peninsula through Georgia...4 to 8
inches, isolated 10 inches.
This rainfall may cause life-threatening flash floods.
SURF: Large swells are affecting the northwestern Bahamas, the
Florida east coast, and the coast of Georgia. These swells are
expected to spread northward along much of the remainder of the
southeastern United States coast during the next couple of days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
TORNADOES: A tornado or two is possible near the immediate east
coast of Florida through today.
