Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from 31N45W to the Windward
Passage will move across the SE waters through Mon when it is
forecast to stall along 22N/23N. Fresh to strong W to NW winds
and rough to very rough seas will follow the front N of 29N.
These marine conditions will gradually shift eastward on Mon. A
trough or low pressure will develop near the Turks and Caicos
Islands early on Tue. The pressure gradient between the trough
and high pressure to the W will support fresh to strong winds
and moderate to rough seas across the waters S of 25N and W of
the trough axis to the coast of eastern Cuba, including the SE
Bahamas. Then, the trough/low will stall in the SE Bahamas
offshore waters trough Wed, with winds and seas diminishing. The
next cold front will enter the NE Florida offshore waters Tue
night before stalling and lifting N of the area late Wed. A
stronger cold front is forecast to move to the NE Florida
offshore waters Thu night into Fri. Fresh to strong winds and
building seas are expected on either side of the front.
