.SYNOPSIS...High pressure over the western North Atlantic will
continue to retreat farther offshore this afternoon, with
southeasterly breezes slackening across the Florida Keys coastal
waters. Light to gentle southeast to south breezes tonight into
Monday will become moderate from the northwest to north Monday
afternoon and evening, as a weak frontal boundary slides through
South Florida and the Keys. High pressure building over the
Southeast will bring moderate easterly breezes back to the Keys
waters by the middle of the week, with fresh breezes developing
later in the week.

The Approximate Shoreward Edge of the Gulf Stream is currently
