Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A stationary front extends from near 23N55W to the Dominican Republic near 19N70W. The front will remain nearly stationary along 20N-21N on Sat. Strengthening high pressure N of the area will push the front farther south on Sun reaching the northern Leeward Islands as a dissipating front. The gradient between the strong high pressure along 31N and lower pressure associated with the stalled front will induce fresh to strong NE to E trade winds south of 23N late this afternoon through Sun. On Sun, fresh to strong southerly flow will set up over the waters east of northeast Florida to about 70W in advance of the next cold front. This cold front is expected to move into the NW forecast waters late Sun. Strong to near-gale force winds are likely on both sides of the front, with brief gales possible Sun night N of 29N between NE Florida and 75W. Seas will build ahead and behind the cold front.
