At 200 PM AST (1800 UTC), the eye of Hurricane Dorian was located
near latitude 24.8 North, longitude 70.3 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.
Data from a reconnaissance plane indicate that with maximum
sustained winds have increased to near 115 mph (185 km/h) with
higher gusts. Dorian is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Additional strengthening is forecast, and
Dorian is anticipated to 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 minimum central pressure recently estimated from an Air Force
reconnaissance plane was 970 mb (28.64 inches).

onshore winds in the northwestern Bahamas. Near the coast,the surge
will be accompanied by large and destructive waves.

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.

of the Bahamas, the Florida east coast, and the southeastern United

cause life-threatening surf and rip current conditions. Please
