DISCUSSION AND OUTLOOK

At 11 a.m. EDT (1500 UTC), the eye of Hurricane Dorian was located near latitude 27.1 North, longitude 78.6 West. Dorian is moving toward the northwest near 2 mph (4 km/h), and a slightly faster motion toward the northwest or north-northwest is expected later today and tonight.

A turn toward the north is forecast by Wednesday evening, followed by a turn toward the north-northeast Thursday morning.

On this track, the core of extremely dangerous Hurricane Dorian will gradually move north of Grand Bahama Island through this evening.  The hurricane will then move dangerously close to the Florida east coast late today through Wednesday evening, very near the Georgia and South Carolina coasts Wednesday night and Thursday, and near or over the North Carolina coast late Thursday and Thursday night.

Data from reconnaissance aircraft indicate that the maximum sustained winds are near 110 mph (175 km/h) with higher gusts. Dorian is expected to remain a powerful hurricane during the next couple of days.

Data from aircraft and buoys indicate that the hurricane is growing in size.  Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km).

The latest minimum central pressure based on data from Air Force Reserve and NOAA reconnaissance aircraft is 955 mb (28.20 inches).

WIND:  Tropical storm and hurricane conditions will continue on Grand Bahama Island through tonight.

Hurricane conditions are expected within the Hurricane Warning area in Florida by this evening.  Hurricane conditions are possible in the Hurricane Watch area as early as Wednesday and could spread northward within the watch through Thursday.

In South Florida, tropical storm conditions are expected within the Tropical Storm Warning area through today.  Along the coast of northeastern Florida and Georgia, tropical storm conditions are expected within the Tropical Storm Warning area on Wednesday.
