Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from the central Atlantic SW to 20N58W then becomes stationary from that point to NE Puerto Rico. Moderate to fresh N to NE winds and rough to very rough seas are ongoing W of the front between 40W and 61W. The tail of the front will begin lifting N through the weekend while weakening. Large NW to W swell behind the front will shift E through Fri. Winds and seas will diminish from west to east through Fri as high pressure builds over the western Atlantic in the wake of the front. Winds are forecast to reach fresh to strong speeds again north of 22N and E of the Bahamas this weekend as the pressure gradient tightens between the remnants of the front and strong high pressure to the north. These winds will support building rough seas across E of the Bahamas. Looking ahead, a strong cold front will push off the SE United States coast early Mon preceded and followed by fresh to strong winds. The front will reach from 31N70W to the southern Bahamas and eastern Cuba by Tue morning. ATLC waters from 27N to 31N W of 77W .TODAY...SE winds less than 10 kt.
