DISCUSSION AND OUTLOOK
At 500 AM EDT (0900 UTC), the eye of Hurricane Dorian was located by NOAA Doppler radar near latitude 26.9 North, longitude 78.4 West. Dorian is stationary just north of Grand Bahama Island. A slow north-northwestward motion is expected to begin this morning. A
turn to the north is forecast by Wednesday evening, followed by a turn to the north-northeast Thursday morning. On this track, the core of extremely dangerous Hurricane Dorian will continue to pound Grand Bahama Island today. 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.
Maximum sustained winds are near 120 mph with higher gusts. Dorian is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Dorian is expected to remain a powerful hurricane during the next couple of days.
Hurricane-force winds extend outward up to 45 miles from the center, and tropical-storm-force winds extend outward up to 160 miles. A wind gust to 61 mph was recently reported at Juno Beach Pier, Florida.
The estimated minimum central pressure is 950 mb.
