DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Hurricane Florence was
located by a NOAA Hurricane Hunter aircraft near latitude 24.4
North, longitude 56.3 West.  Florence is moving toward the west near
6 mph (9 km/h), and this general motion is expected to continue
today.  A west-northwestward motion with an increase in forward
speed is expected by Monday, and that motion is forecast to continue
through mid-week.  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
U.S. coast on Thursday.

Aircraft data indicate that maximum sustained winds have increased
to near 75 mph (120 km/h) with higher gusts.  Florence is forecast
to rapidly strengthen to a major hurricane by Monday, and is
expected to remain an extremely dangerous major hurricane through
Thursday.

Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 115 miles
(185 km).

The latest minimum central pressure reported by a NOAA Hurricane
Hunter Aircraft is 984 mb (29.06 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Florence are affecting Bermuda and are
beginning to reach 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.
