was located near latitude 25.0 North, longitude 70.7 West. Dorian is
moving toward the west-northwest near 9 mph (15 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
Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts. Dorian is a category 3 hurricane on the Saffir-Simpson

Dorian is anticipated to remain an extremely dangerous hurricane
while it moves near the northwestern Bahamas and approaches the
Florida peninsula into early next week.

center and tropical-storm-force winds extend outward up to 115 miles
The estimated minimum central pressure is 970 mb (28.65 inches).

area in the northwestern Bahamas by Sunday, with tropical storm
winds beginning by Saturday night.

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.

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.
