DISCUSSION AND OUTLOOK
At 200 PM EDT (1800 UTC), the distinct eye of Hurricane Dorian was
located near latitude 26.1 North, longitude 73.9 West. Dorian is
moving toward the west near 8 mph (13 km/h), and a slower westward
motion should 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, be near or over the
northwestern Bahamas on Sunday, and move near the Florida east coast
late Monday through Tuesday.
Data from an Air Force reconnaissance plane indicate that the
maximum sustained winds are near 150 mph (240 km/h) with higher
gusts. Dorian is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some fluctuations in intensity are likely, but
Dorian is expected to remain a powerful hurricane during the next
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 115
miles (185 km).
The minimum central pressure reported by a reconnaissance plane was
945 mb (27.91 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected in the hurricane warning
area across the northwestern Bahamas by Sunday, with tropical storm
winds beginning tonight.
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 Great Abaco and Grand Bahama. 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 25 inches.
Coastal sections of the southeast United States...4 to 8 inches,
isolated 12 inches.
Central Bahamas...2 to 4 inches, isolated 6 inches.
This rainfall may cause life-threatening flash floods.
SURF: Swells will begin affect 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.
