Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A stationary front extending from 31N69W to Cuba is forecast to lift northward towards the NW Bahamas and the Straits of Florida this evening. Strong high pressure building north of the area will lead to the development of strong to near- gale force NE to E winds and building seas over the northern Bahamas and Straits of Florida through Wed, with these winds spreading northward through Thu night. Gale force winds are possible east of Florida later this week. An area of low pressure is forecast to move from the Gulf of Mexico, across Florida, and into the Atlantic waters this weekend. A large area of gale force winds are possible east of the low. ATLC waters from 27N to 31N W of 77W ...GALE CONDITIONS POSSIBLE... .TONIGHT...NE winds 15 to 20 kt.
