DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the center of Hurricane Florence was
located near latitude 24.9 North, longitude 58.9 West. Florence is
moving toward the west-northwest near 9 mph (15 km/h). A
west-northwestward motion with an increase in forward speed is
expected during the next couple of days.  A turn toward the
northwest is forecast to occur Wednesday night or Thursday. 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 southeastern coast of the United
States on Thursday.

Satellite imagery indicates that the maximum sustained winds have
increased to near 105 mph (165 km/h) with higher gusts. Rapid
strengthening is forecast, and Florence is forecast to become a
major hurricane this morning, and is expected to remain an extremely
dangerous major hurricane through Thursday.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 125 miles
(205 km).

The estimated minimum central pressure is 969 mb (28.62 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Florence are affecting Bermuda and
portions of the U.S. East Coast.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
