Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front stretches from near 31N59W to 25N70W, and is a stationary front from there to the Straits of Florida. The front will extend from near 26N55W to 23N67W and stationary to South Florida this evening, then gradually dissipate Sat from 23N55W to 23N65W. Strong winds and rough seas will impact waters north of 27N and east of 70W, on both sides of the front through this evening. Southerly winds offshore Florida will increase to strong late tonight and to gale force on Sat off northern Florida in advance of a stronger cold front that is expected to move across the waters off northeast Florida by late Sat. This front is forecast to reach from near 31N74W to South Florida early Sun, from near 31N57W to the central Bahamas early Mon and from near 23N55W to 23N70W early Tue. On Sat night through Mon, after the gales end, fresh to strong winds are expected on either side of this front north of 29N as it moves eastward. Looking ahead to Tue and Tue night, gale force southerly winds are expected to precede yet another strong cold front over the waters east of NE Florida, while strong to near gale force southerly winds are likely elsewhere north of 27N and west of 65W.
