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

.SYNOPSIS...The pressure gradient between strong high pressure
over the central Atlantic and lower pressure over the SW
Caribbean will sustain strong to near gale-force trades over the
SW and much of the central Caribbean, including the Gulf of
Venezuela, through Fri morning. Moderate to fresh trades are
forecast elsewhere in the eastern and central basin through Sun.
A cold front will enter the NW Caribbean on Fri morning,
followed by fresh to strong NE winds. The front is expected to
stall from central Cuba to the Yucatan Peninsula Fri night, then
gradually dissipate over the NW Caribbean on Sat.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...The pressure gradient between a 1031 mb high over
the central Atlantic and low pressure across the SW Caribbean
will sustain fresh E-NE winds south of 22N and in the approach to
the Windward Passage through tonight before diminishing on Fri.
A new cold front has emerged off of the NE Florida coast this
morning, followed by fresh N winds. The cold front will move
southeastward and extend from 31N72W to the Florida Straits
tonight, from 31N63W through the central Bahamas by Fri night,
and then dissipate from 31N59W the NW Bahamas by Sun morning. A
tight pressure gradient in the wake of the front will produce
increasing NE winds across much of the forecast area Sat,
gradually diminishing from west to east Sun.
