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

.SYNOPSIS...The pressure gradient between strong high pressure
centered along the eastern U.S. and low pressure over
northwestern Colombia will continue to support gales off the
coast of Colombia through Sun morning, with gale force winds
likely to pulse again Sun night. Strong winds will develop in
the northeastern Caribbean Sat evening through Sun night as the
front becomes stationary over the forecast waters. Winds and
seas will diminish across much of the area early next week.
Another cold front may bring strong northerly winds to the
northwest Caribbean Mon night through Tue night. This front is
expected to become stationary from near Windward Passage to the
southwest Caribbean on Wed and Wed night and weaken.
