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

.SYNOPSIS...A strong deep-layered trough continues across the
Caribbean from eastern Cuba to Nicaragua will lift out to the NE
through Sat night. This feature will support active weather
across the central portions of the basin, which will gradually
shift NE and into the Atlantic through Fri night. A broad and
weak trough will prevail across the north-central Caribbean
tonight through Sat, yielding moderate trade winds across the E
portions and moderate to fresh winds across NW portions of the
basin. Smoke due to agricultural fires in Central America
continues across the Gulf of Honduras, and spreads NW to the
Yucatan coast.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Scattered showers and thunderstorms along with fresh
winds and building seas will persist overnight into Fri near a
developing low pressure area roughly half way between Bermuda
and Hispaniola. Expect fresh to strong winds and rough seas near
the low pressure late Fri through Sat as it makes its closest
point of approach of 210 nm to the southeast of Bermuda Sat
afternoon before weakening as it moves slowly into the north
central Atlantic through the early part of the week. Farther
west, weak high pressure will build between Bermuda and the
central Bahamas Sat into Sun following the low pressure. Looking
ahead, moderate to fresh SW winds and building seas are possible
north of the Bahamas and off northeast Florida by Mon night as
the high pressure shifts eastward ahead of a cold front expected
to move off the southeast U.S. coast by mid week.
