Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from near 31N62W to the eastern tip of Cuba. A secondary cold front trails it, extending from near Bermuda to Miami, FL. The secondary front will speed up and merge with the first front by late Thu. The main front will reach from near 31N48W to the N coast of Hispaniola Thu evening. Gale force winds and high seas are expected both ahead of and behind this front, to the north of 28N through late Thu afternoon. The gale winds will shift E of 55W Thu afternoon. The front will stall and weaken along 20N Fri through Sat as strong high pressure builds across the western Atlantic. The gradient between the strong high pressure along 31N and lower pressure associated with the stalled front will induce fresh to strong ENE trade winds south of 23N Fri through Sun. On Sun, the front will dissipate as fresh to strong southerly flow sets up over the waters east of northeast Florida to 69W in advance of the next cold front. This cold front is expected to move into the NW forecast waters late Sun, followed by fresh to strong west to northwest winds. Seas will build both east and west of this cold front.
