At 1100 AM AST (1500 UTC), the eye of Hurricane Florence was
located near latitude 25.0 North, longitude 60.0 West. Florence is
moving toward the west near 13 mph (20 km/h). A west-northwestward
motion with an increase in forward speed is expected during the next

late Wednesday night. On the forecast track, the center of Florence
will move over the southwestern Atlantic Ocean between Bermuda and
the Bahamas Tuesday and Wednesday, and approach the coast of South
Carolina or North Carolina on Thursday.
Satellite data indicate that maximum sustained winds have increased
to near 115 mph (185 km/h) with higher gusts. Florence is a
category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale.
Further strengthening is anticipated, and Florence is expected to be
an extremely dangerous major hurricane through Thursday.
Hurricane-force winds extend outward up to 30 miles (45 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
(220 km).
The estimated minimum central pressure is 962 mb (28.41 inches).
