Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...High pressure over the area will continue to support
fresh to strong E winds across the waters south of 24N through 
Mon night. A cold front will move over the far northwest waters 
Mon night, then transition to a stationary front as its reaches 
from near 28N65W to 31N79W Tue night. Strong east winds will 
develop north of this boundary Tue and Tue night as strong high 
pressure to its north builds southward. The stationary front
will lift back to the north as a warm front in response to low 
pressure that will move northeastward from the Gulf of Mexico to 
off the coast of the Carolinas on Wed morning. The low pressure 
will strengthen as it quickly tracks northeastward through Thu 
night pushing a strong cold front across the waters north and 
northeast of the Bahamas. This front will be preceded and 
followed by fresh to strong winds and building seas.
