Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A slow moving cold front extends from 31N50W to near 24N60W, where it becomes stationary and continues through the central Bahamas and Straits of Florida. This front will drift southward tonight before becoming fully stationary along 23N by Sat. The pressure gradient between the strong high pressure building north of the area and the front will result in near gale to gale-force NE to E winds and high seas over the waters W of 65W and north of 23N through tonight. The front will then gradually dissipate Sat night through Sun, in advance of Gulf of Mexico low pressure that will move NE across Florida Sat night. This low will move through the NW Atlantic waters Sun, when a large area of southerly gales will develop SE of the low. Numerous thunderstorms in association with this low will provide locally higher winds and seas this weekend.
