DISCUSSION AND OUTLOOK
----------------------
At 900 PM GMT (2100 UTC), the center of Hurricane Isaac was located 
near latitude 41.3 North, longitude 38.4 West. Isaac is moving 
toward the northeast near 18 mph (30 km/h).  A slower east-northeast 
to northeast motion is expected during the next couple of days.

Maximum sustained winds are near 100 mph (155 km/h) with higher
gusts.  Gradual weakening is expected, and Isaac is forecast to be
a post-tropical cyclone on Monday.

Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 195 miles
(315 km).

The estimated minimum central pressure is 968 mb (28.59 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Isaac and a large wind fetch from a
deep-layer trough will affect the Azores over the next few days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.
