Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...The tail end of a stationary front is analyzed from 24N44W to 21N65W. Fresh to strong NE to E winds and rough seas to 9 ft are ongoing N of the front between 55W and 64W. The front will lift N through the weekend while weakening. High pressure over the NW Atlantic will build while it shifts SE to the central Atlantic waters through early next week. The pressure gradient between the associated ridge and the remnants of the aforementioned front will lead to the development of fresh to strong winds north of 22N and E of the Bahamas this weekend. These winds will support building rough seas across E of the Bahamas. Looking ahead, A low pres system will develop E of the area, with increasing winds to gale-force possible mainly N of 27N and E of 56W by Mon afternoon/night. To the W, a strong cold front will push off the SE United States coast early Mon preceded and followed by fresh to near-gale force winds. The front will reach from 31N68W to the Turks and Caicos and eastern Cuba Tue morning, and from Bermuda to Puerto Rico Wed morning. ATLC waters from 27N to 31N W of 77W .TODAY...SE winds 10 to 20 kt.
