Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A weakening stationary front from near 25N55W
southwestward to the Turks and Caicos Islands and eastern Cuba
will weaken and dissipate through tonight. Rough to very rough

approach South Florida Mon, enter the Atlantic and move E-NE

front and low Tue through Wed. By late Wed night, marine
conditions will improve under a weak pressure pattern. Another
front may move offshore the SE United States Thu night.
