Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary front from 31N60W to the northern
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 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.
