Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A stationary front extends from near 24N65W to the NW Bahamas to near Fort Lauderdale, Florida. This front will be overtaken by a reinforcing surge of high pressure tonight, then move south to along 20N by Mon morning, and into the Greater Antilles Mon night. Southerly flow will increase across the waters E of north-central Florida Mon into Tue. Low pressure near Bermuda will bring strong W winds to the NE waters Tue night through Wed. A stronger cold front will move off the SE U.S coast Wed night while the associated low pressure rapidly intensifies N of the area through the end of the week. Gale force winds and very large seas are expected with this system, mainly N of 27N. ATLC waters from 27N to 31N W of 77W ...GALE CONDITIONS POSSIBLE... .TONIGHT...SE winds 10 to 15 kt.
