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

.SYNOPSIS...A broad area of low pressure over the western
Caribbean Sea is producing widespread but disorganized shower and
thunderstorm activity while it moves west-northwestward. Some
development of this system is possible over the northwestern
Caribbean Sea or over the southwestern Gulf of Mexico during the
next few days. Expect moderate to fresh trade winds through Mon
night, with the exceptions of fresh to strong southeast winds
over the far western Caribbean through Sat night, and light to
gentle winds over the southwestern Caribbean. Winds and seas are
expected to increase in the Tropical N Atlantic Sun, the eastern
Caribbean Mon, then the central Caribbean Tue and Tue night as a
strong tropical wave, possibly a tropical cyclone, moves through.
Storm conditions are possible near this feature in the Tropical N
Atlantic Sun evening, spreading westward through time.
