.SYNOPSIS...A broad surface trough over the Leeward Islands
results in a few showers over the eastern Caribbean. The
subtropical ridge over the western Atlantic will gradually slide
eastward, supporting moderate to fresh easterly winds over much
of the basin through early next week. Locally strong NE winds
may pulse at night off NW Colombia tonight. Meanwhile, locally
rough seas, in NE swell, will persist across the NE Caribbean
passages into early next week. Looking ahead, a cold front may
approach the NW Caribbean early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary front extends from 31N67W to South
Florida. The stationary portion of the front is likely to
dissipate today into Fri, while the cold front, mainly north of
our area, continues eastward. High pressure will follow the
front. The next cold front is expected to clip the waters
offshore of NE Florida late Fri into Sat, resulting in fresh to
strong southerly winds and moderate to locally rough seas N of
28N and east of 70W. Conditions will improve Sun, but a stronger
cold front reaching the same area on Mon. Fresh to strong winds
and rough seas will develop north of 26N Mon and quickly shift
eastward. Conditions will improve Tue.
