SYNOPSIS FOR THE SW N ATLC INCLUDING THE BAHAMAS

.SYNOPSIS...Strong high pres centered over the central Atlantic 
will shift eastward through Mon in response to a cold front that
extends from 31N75W to the central Bahamas and to W central Cuba
early this afternoon. The cold front will reach from near 31N75W
to the central Bahamas and to central Cuba this evening, then
become stationary from 31N73W to the central Bahamas and to 
eastern Cuba on Sun. A post-frontal trough will quickly swing 
across the NW waters and help to move the cold front a little 
farther to SE from near 31N65W to the Windward Passage by Mon 
evening before it weakens thereafter through Wed. A strong cold 
front will move off the SE United States coast on Wed, reach
from near 31N74W to near 26N75W and to E central Cuba Wed night 
and from near 25N65W to vicinity SE Bahamas by late Thu. Strong 
NW winds will follow in behind this front. By late Thu these 
winds are expected to be mainly over the eastern half of the 
area.
