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

.SYNOPSIS...Moderate to fresh winds and moderate seas are
expected across the E and central Caribbean, with light to
gentle winds and slight to moderate seas across the NW and SW
portions of the basin through at least Sat. Looking ahead, a
broad area of low pressure could form early next week over the
western and northwestern Caribbean Sea. Thereafter, gradual
development of this system is possible, and a tropical
depression could form as the system moves slowly to the north or
northwest over the northwestern Caribbean Sea and into the
southeastern Gulf of Mexico through the middle part of next
week. There is a medium chance of tropical cyclone formation in
the next seven days.
