DISCUSSION AND OUTLOOK
At 500 AM EDT (0900 UTC), the center of Hurricane Dorian was located
near latitude 26.4 North, longitude 76.0 West. Dorian is moving
toward the west near 8 mph (13 km/h), and a slower westward motion
should occur for the next day or two, followed by a gradual turn
toward the northwest. On this track, the core of Dorian should be
near or over portions of the northwestern Bahamas later today and
tonight, and should move closer to the Florida east coast late
Monday through Tuesday night.
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 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 (165 km).
The estimated minimum central pressure is 934 mb (27.58 inches).
