DISCUSSION AND OUTLOOK
----------------------
At 1100 PM EDT (0300 UTC), the center of the eye of Hurricane
Florence was located by NOAA Doppler radar and an Air Force Reserve
Hurricane Hunter aircraft near latitude 34.0 North, longitude 76.8
West.  Florence is moving toward the northwest near 6 mph (9 km/h).
A turn toward the west-northwest and west at a slow forward speed
is expected through Friday, followed by a slow west-southwestward
motion Friday night and Saturday.  On the forecast track, the
center of Florence is expected to move inland across extreme
southeastern North Carolina and extreme eastern South Carolina
Friday and Saturday.  Florence will then recurve across the western
Carolinas and the central Appalachian Mountains early next week.

Data from the Hurricane Hunter aircraft, coastal surface
observations, and NOAA Doppler radar indicate that maximum sustained
winds are near 90 mph (150 km/h) with higher gusts.  Little change
in strength is expected before Florence moves inland on Friday.
More significant weakening is expected over the weekend and into
early next week while Florence moves farther inland.

Hurricane-force winds extend outward up to 80 miles (130 km) from
the center, and tropical-storm-force winds extend outward up to 195
miles (315 km).  A Weatherflow station at Fort Macon, North
Carolina recently reported a sustained wind of 77 mph (124 km/h)
with a gust to 100 mph (161 km/h).

A storm surge of 10 feet above normal levels was reported by the
National Weather Service office in Morehead City, North Carolina,
at the Cherry Branch Ferry Terminal on the Neuse River, courtesy of
the North Carolina Department of Transportation.

The minimum central pressure reported by the aircraft is 956 mb
(28.23 inches).
