    DISCUSSION AND OUTLOOK
    ----------------------
    At 200 PM AST (1800 UTC), the eye of Hurricane Sam was located
    near latitude 29.1 North, longitude 61.9 West. Sam is moving toward
    the north near 21 mph (33 km/h). A turn toward the north-northeast,
    at a slightly slower forward speed, is expected by tonight, followed
    by a northeastward motion Saturday night through Monday. On the
    forecast track, the center of Sam will pass well to the east of
    Bermuda tonight.

    Data from the Air Force Hurricane Hunters indicate that maximum
    sustained winds remain near 150 mph (240 km/h) with higher gusts.
    Sam is a category 4 hurricane on the Saffir-Simpson Hurricane Wind
    Scale. Although fluctuations in intensity are still possible today,
    weakening is forecast during the next couple of days. However, Sam
    is expected to remain a major hurricane through at least Saturday
    night.

    Hurricane-force winds extend outward up to 60 miles (95 km) from
    the center and tropical-storm-force winds extend outward up to 205
    miles (335 km).

    The minimum central pressure based on data from the Air Force
    Hurricane Hunters is 937 mb (27.67 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    Key messages for Sam can be found in the Tropical Cyclone Discussion
    under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC, and on the
    web at hurricanes.gov/graphics_at3.shtml?key_messages.

    WIND: Tropical storm conditions are possible on Bermuda beginning
    tonight or early Saturday.

    SURF: Swells generated by Sam will impact the northern Leeward
    Islands and the Greater Antilles, including Puerto Rico, during the
    next couple of days. Swells are expected to reach Bermuda and the
    Bahamas this afternoon, and then spread to the United States east
    coast and Atlantic Canada on Saturday. These swells could cause life-threatening surf and rip current conditions. Please consult
    products from your local weather office.
