A surface high pressure across the north-central Atlantic will
yield moderate easterly winds across the local waters during the
next several days. An increase in winds and shower activity is
expected on Sunday as a tropical wave/easterly disturbance moves
across the eastern Caribbean. Although the northerly swell will
continue to subside, a smaller secondary northeasterly swell will
continue to affect the local waters during the weekend.
