Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from 31N72W to South Florida will reach from near 31N70W to the Straits of Florida this morning, from near Bermuda to the central Bahamas early this afternoon, then weaken as it reaches from near 31N56W to eastern Cuba by Wed morning. Fresh to strong winds and rough seas are ahead and behind the front, with gale force winds over the waters north of 27N. The gale force winds behind the front end this morning while those east of the front end late this afternoon. Weak low pressure may form along the front near 30N56W on Thu morning, with the front reaching northern Hispaniola. High pressure in its wake will quickly shift eastward through Fri night, allowing for fresh to strong southerly winds to develop over the western half of the forecast waters as low pressure tracks northeastward from the Gulf of Mexico to over northern Florida, and to north of the area Sat and Sat night. These winds will expand in coverage as they shift eastward ahead of a cold front that will trail from the low over the western waters.
