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

.SYNOPSIS...A very pronounced deep-layer trough that extends
across Cuba to Panama will lift E-NE across Hispaniola through
tonight. Active weather east of the trough will gradually shift
NE into the Atlantic through tonight. Generally moderate trade
winds are expected across the basin, except for fresh to strong
winds pulsing in the Gulf of Honduras at night through Tue
night. Moderate to fresh trade winds are forecast to develop
over the central Caribbean Mon through Wed. A low latitude
tropical wave is currently in the Tropical N Atlantic near 57W.
The wave will cross the Windward Islands late this afternoon
into tonight, move through the E Caribbean Sun through Mon
night, then become ill- defined as it approaches the central
Caribbean Tue. Gusty winds and active weather are expected with
the wave. Smoke due to agricultural fires in Central America may
persist across the Gulf of Honduras over the weekend.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A trough extends from near 29N62W WSW to weak low
pressure of 1012 mb near 28N67W to the Windward Passage.
Scattered showers and thunderstorms are presently in the NW
semicircle of the low to 66W.The low is expected to move NE
during the next day or so, and development into a tropical or
subtropical cyclone is not expected due to unfavorable
environmental conditions. Otherwise, relatively weak high
pressure will remain over the region for the next few days. The
associated gradient will support moderate winds and 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
that is expected to move off the southeastern U.S. coast Mon
night, move across the waters east of northern Florida early on
Tue, reach from near 31N79W to east-central Florida early on Wed
and from near 31N78W to 29N79W and stationary to east-central
Florida Wed night.
