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

.SYNOPSIS...Moderate to fresh E winds and seas of 4-6 ft will
continue into Thu morning across central and west-central
portions of the Caribbean as a tight pressure gradient between
the Colombian low and weak ridging in the southwestern Atlantic
prevails. For Thu through the weekend, moderate trades and
slight seas will occur across the central Caribbean, with light
to gentle winds occurring across northwest and southwest
portions of the basin. Looking ahead, a broad area of low
pressure could form this weekend over the northwestern Caribbean
Sea. Thereafter, some slow development of this system is
possible through early next week while it moves slowly to the
north or northwest over the northwestern Caribbean Sea. There is
a low probability of formation in the next seven days.
