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

.SYNOPSIS...Elongated low pressure extending from the nearby
Atlantic along 70W into the central Caribbean is combining with
high pressure centered over the middle Atlantic U.S. coast to
support fresh NE to E winds in the NW Caribbean. The southern
end of this trough will shift W-NW and into the W central
Caribbean through early this week, with winds diminishing across
the NW Caribbean later today. Scattered strong thunderstorms
occurring along and E of the trough will shift westward with the
trough through Mon. Large N-NE swell across the W Atlantic will
continue to move through the NE Caribbean Passages through
today. A strong cold front will enter the NW Caribbean Wed.
