DISCUSSION AND OUTLOOK
At 1100 PM EDT (0300 UTC), the center of Hurricane Dorian was
located near latitude 25.5 North, longitude 71.4 West. Dorian is
moving toward the west-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 tonight and tomorrow, be near or over the
northwestern Bahamas on Sunday, and be near the Florida east
coast late Monday.
Data from a NOAA Hurricane Hunter aircraft indicate that the
maximum sustained winds have increased to near 140 mph (220 km/h)
with higher gusts. Dorian is a category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Some additional strengthening
is possible tonight and Saturday. Although fluctuations in
intensity are possible early next week, Dorian is expected to
remain a powerful hurricane during the next few days.
Hurricane-force winds extend outward up to 30 miles (45 km) from the
center and tropical-storm-force winds extend outward up to 105 miles
The latest minimum central pressure based on data from a NOAA
reconnaissance aircraft is 948 mb (28.00 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected in the hurricane warning
area in the northwestern Bahamas by Sunday, with tropical storm
winds beginning Saturday night.
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...10 to 15 inches, isolated 20 inches.
Coastal sections of the southeast United States...6 to 12 inches,
isolated 18 inches.
Central Bahamas...2 to 4 inches, isolated 6 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.
