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

.SYNOPSIS...Disorganized showers and thunderstorms located over
the western Caribbean Sea are associated with a very broad area
of low pressure. Environmental conditions appear favorable for
gradual development of this system during the next several days.
A tropical depression is likely to form while the system moves
slowly northward across the northwestern Caribbean Sea and Gulf
of Mexico through the end of the week. There is a high chance of
tropical cyclone formation in the next seven days. Regardless of
development, winds and seas will increase over the NW Caribbean
early this week.
