Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A dissipating stationary front extends westward into the waters to around 27N65W. Moderate to fresh winds on the north side of this front will diminish today. Northeastward moving low pressure of 1010 mb near 32N73W has a medium potential of tropical cyclone formation as it moves away from the area today into Thu. Extending southwestward from this low is a trough of low pressure that reaches the central Atlantic coast of Florida. This feature will merge with a weakening stationary front that earlier moved offshore the southeastern U.S. The remnant front will then push slowly east while weakening, reaching the NW Bahamas tonight, central Bahamas Thu night, then stretch from near 24N70W to 29N65W by Fri night. In the wake of this front, and partially associated with swell from the aforementioned low pressure, seas north and northeast of the Bahamas may reach 8 to 10 ft Fri and Sat.
