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

.SYNOPSIS...A cold front extending from eastern Cuba to just
west of Jamaica and to near the border between Nicaragua and
Costa Rica will stall tonight, then weaken and dissipate during
the weekend. Fresh to locally strong N winds are behind the
front with seas to 8 ft. These conditions will gradually
diminish through Sun. A tightening pressure gradient between
developing low pressure in the southwestern Caribbean and high
pressure building over the southeastern United States will
promote fresh NE winds in the Atlantic Passages and in the lee
of Cuba on Sat, and moderate to fresh NE to E winds and moderate
seas in E swell will develop across much of the basin Sun into
the middle of next week. A weak surface trough from 17N70W to
12N72W is producing scattered showers and thunderstorms. This
feature is forecast to possibly reach the western Caribbean by
Sun and stall into next week.
