DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), reports from An Air Force Reserve
reconnaissance aircraft indicate that the center of the eye of
Hurricane Florence was located near latitude 30.4 North, longitude
71.8 West. Florence is moving toward the northwest near 16 mph
(26 km/h) and this general motion, accompanied by a gradual decrease
in forward speed, is expected to through Saturday. On the forecast
track, the center of Florence will move over the southwestern
Atlantic Ocean between Bermuda and the Bahamas today, and approach
the coast of North Carolina or South Carolina in the hurricane
warning area on Thursday and Friday and move slowly near the
coastline through Saturday.

The reconnaissance aircraft found that maximum sustained winds have
decreased to near 125 mph (205 km/h) with higher gusts. Florence is
now a category 3 hurricane on the Saffir-Simpson Hurricane Wind
Scale.  Some fluctuations in strength will be possible through
Thursday morning.  Although slow weakening is expected to begin by
late Thursday, Florence is still forecast to be an extremely
dangerous major hurricane when it nears the U.S. coast late Thursday
and Friday.

Hurricane-force winds extend outward up to 70 miles (110 km) from
the center and tropical-storm-force winds extend outward up to 175
miles (280 km).  A NOAA buoy located about 100 miles northeast of
Florence's eye recently reported a sustained wind of 53 mph (85
km/h) and a gust to 74 mph (119 km/h).

The minimum central pressure based on reports from the
reconnaissance aircraft is estimated to be 948 mb (27.99 inches).
