Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...Weak low pressure off the coast of Colombia in the
south-central Caribbean has increased shower and thunderstorm
activity. Environmental dry air is still likely to prevent
significant development of this system as it begins to drift
slowly westward later this week. This system has a low chance of
formation in the next 48 hours and 7 days. High pressure
building toward the Greater Antilles Tue into Wed will lead to
fresh to strong NE winds in the Windward Passage and just S of
Hispaniola. Elsewhere, winds will be moderate or less into late
week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front that extends E of Bermuda to east of 
the Turks and Caicos Islands will slide E through mid-week, 
before moving E of the region. Southerly gales ahead of the front
N of 29N between 60W and 65W will diminish today. Behind the 
front, N winds will reach gale force by this evening into tonight
N of 29N between 60W and 65W, then track eastward through Tue 
night to 55W. Very rough to high seas will accompany these gales,
with northerly swell leading to seas of over 12 ft for areas N 
of 20N and E of 65W by Wed. Looking ahead, increasing southerly 
flow is likely mid-week offshore Florida in advance of the next 
cold front.
