DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of the eye of Hurricane
Florence was located by NOAA Doppler weather radars and surface
observations to be just inland near latitude 34.1 North, longitude
77.9 West. Florence is moving toward the west near 6 mph (9 km/h). A
slow westward to west-southwestward motion is expected today through
Saturday. On the forecast track, the center of Florence will move
further inland across extreme southeastern North Carolina and
extreme eastern South Carolina today and Saturday.  Florence will
then move generally northward across the western Carolinas and the
central Appalachian Mountains early next week.

Maximum sustained winds remain near 90 mph (150 km/h) with higher
gusts.  Gradual weakening is forecast later today and tonight.
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 wind gust to 105 mph (169 km/h) recently occurred
at the Wilmington Airport, an Amateur Radio operator in Kirkland
recently reported a wind gust to 98 mph (158 km/h), and a wind gust
of 95 mph (153 km/h) was also recently reported by a Weatherflow
private weather station at Federal Point.

The minimum central pressure estimated from surface data from the
NOAA NOS observing site at Johnny Mercer Pier in Wrightsville Beach
is 958 mb (28.29 inches).
