Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from 24N65W to the NW Bahamas
then stalls to near West Palm Beach, Florida. This front will be
overtaken by a reinforcing surge of high pressure tonight, then
move S to along 21N by Sun night, 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 into 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.
