SYNOPSIS FOR THE SW N ATLC INCLUDING THE BAHAMAS

.SYNOPSIS...A weak cold front moving off the southeast United
States coast will quickly stall and dissipate across the
northwest waters on Mon. Gentle to moderate winds will prevail
north of the ridge with moderate to fresh winds expected
generally south of 25N, except becoming strong along the north
coast of Hispaniola and the north approach to the Windward
Passage each evening. The ridge will be reinforcing by a
stronger high pressure Mon through Wed to produce strong winds
and high seas across the entire region S of 25N.
