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

.SYNOPSIS...A cold front extending from central Cuba to central
Honduras will progress southeastward through Fri night to 20N77W
to 10N82W, before stalling on Sat and gradually dissipating.
Fresh to locally strong N winds will occur in the wake of the
front, with the strongest winds occurring offshore of Nicaragua
Fri night into Sat. Moderate seas will also develop behind the
front, with locally rough seas of 8 to 9 ft expected through the
Yucatan Channel tonight into Fri. A tightening pressure gradient
between developing low pressure in the southwestern Caribbean
and high pressure overtaking the southeastern United States will
promote fresh NE winds in the Atlantic Passages and in the lee
of Cuba on Sat, with moderate to fresh E to NE winds and
moderate seas in NW swell developing across much of the basin
Sun through early next week.
