    At 300 PM GMT (1500 UTC), the center of Post-Tropical Cyclone Isaac
    was located near latitude 44.8 North, longitude 29.1 West. The
    post-tropical cyclone is moving toward the east-northeast near 17
    mph (28 km/h) and a turn to the northeast is expected with a similar
    forward motion for the next several days.

    Maximum sustained winds have decreased to near 60 mph (95 km/h)
    with higher gusts. Gradual weakening is forecast over the next
    several days.

    Tropical-storm-force winds extend outward up to 185 miles (295 km)
    from the center.

    The estimated minimum central pressure is 983 mb (29.03 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    SURF: Swells generated by Isaac 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.
