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 tonight. A
broad area of low pressure should form over the next few days
over the northwestern Caribbean Sea and the adjacent portions of
Central America. Thereafter, gradual development of this system
is likely, and a tropical depression could form as the system
moves slowly northward across the northwestern Caribbean Sea and
Gulf of Mexico through the end of next week. There is a high
chance of tropical cyclone formation in the next seven days.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...An area of low pressure is centered near 26N55W.
Although it is producing scattered showers and thunderstorms,
the
low is embedded in a very dry environment, therefore significant
development is not expected while it moves N at around 5 kt over
the central subtropical Atlantic. Otherwise, a weak cold front
will move off the SE coast of the US Sunday, then slowly move
across the waters N of 25N into Mon night.
