Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary front extending from 31N60W to the
central Bahamas is followed by fresh to strong NE winds and
moderate to rough seas. This front will dissipate through today,
and high pressure north of the front will shift eastward,
allowing winds and seas to diminish. Another weak front will
stall off the northeast Florida coast by Mon, then lift
northward Mon night. Expect southerly winds and building seas
north of 29N and west of 75W late Mon and Tue as low pressure
moves from the northern Gulf to the Carolinas. Looking ahead,
these strong southerly winds will shift eastward Tue night into
Wed, north of 28N ahead of a cold front moving off the northeast
Florida coast Tue night. This front will reach from Bermuda to
South Florida by late Wed, and from 31N60W to eastern Cuba by
late Thu. Meanwhile, strong winds and rough seas will accompany
a trough moving westward into the waters northeast of the
Leeward Islands Sun through Tue night.
