    DISCUSSION AND OUTLOOK
    ----------------------
    At 800 AM AST (1200 UTC), the center of Tropical Storm Ernesto was
    located near latitude 19.8 North, longitude 67.2 West. Ernesto is
    moving toward the northwest near 16 mph (26 km/h). A turn toward
    the north-northwest and north with a gradual decrease in forward
    speed is expected tonight and Thursday. On the forecast track, the
    center of Ernesto will move northward away from Puerto Rico through
    today. Ernesto should then move over the western Atlantic later in
    the week and be nearing Bermuda on Saturday.

    Maximum sustained winds remain near 70 mph (110 km/h) with higher
    gusts. Ernesto is expected to become a hurricane later today and
    could become a major hurricane in a couple of days.

    Tropical-storm-force winds extend outward up to 150 miles (240 km)
    from the center.

    The estimated minimum central pressure based on dropsonde data is
    991 mb (29.26 inches).
