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 through at least
Sat. Looking ahead, a broad area of low pressure could form
early next week over the 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
southern Gulf of Mexico through the middle part of next week.
There is a medium chance of tropical cyclone formation in the
next seven days.
