DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), data from NOAA Doppler weather radars
indicate that the center of the eye of Florence was located near
latitude 33.7 North, longitude 76.2 West. Florence is moving toward
the west-northwest near 5 mph (7 km/h), and this general motion is
forecast to continue into Friday. A slow westward to west-
southwestward motion is expected Friday night and Saturday. On
the forecast track, the center of Florence will approach the coasts
of North and South Carolina later tonight, then move near or over
the coast of southern North Carolina and northeastern South Carolina
in the hurricane warning area on Friday. A slow motion across
portions of eastern and central South Carolina is forecast Friday
night through Saturday night.

Doppler radar data indicate that maximum sustained winds have
decreased to near 100 mph (155 km/h) with higher gusts. Little
change in strength is expected before the eye of Florence reaches
the coast, with slow weakening expected after the center moves
inland or meanders near the coast. More significant weakening is
forecast on Saturday as Florence moves farther inland over central
South Carolina.

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 NOAA reporting station at Cape Lookout, North
Carolina, recently reported a sustained wind of 68 mph (109 km/h)
and a gust to 85 mph (137 km/h).

The estimated minimum central pressure is 955 mb (28.20 inches).
