Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...Fresh to locally strong NE winds and rough seas
persist over the northwest Caribbean, north of a stationary
front reaching from central Cuba to Belize. High pressure north
of the area is supporting moderate to fresh easterly winds and
moderate seas elsewhere across the basin. The front will
dissipate and the high pressure shifts eastward into the western
Atlantic late today, allowing winds and seas to diminish and
conditions to remain relatively benign into the middle of next
week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary front from just E of Bermuda to central
Cuba is followed by fresh to strong NE winds and moderate to
rough seas. This front will gradually dissipate through Sun, and
high pressure north of the front will shift eastward, allowing
winds and seas to diminish. Another weak front will stall off
the northeast Florida coast Mon, then lift northward Mon night.
Expect southerly winds and building seas north of 29N and west of
75W Tue as low pressure moves from the northern Gulf to the
Carolinas. Looking ahead, these strong southerly winds will shift
eastward north of 28N into the middle of next week, ahead of a
cold front moving off the northeast Florida coast Tue night into
Wed. This front will reach from Bermuda to South Florida by late
Wed. Meanwhile, strong winds and rough seas will accompany a
trough moving westward into the waters northeast of the Leeward
Islands Sun into Tue night.
