No watches, warnings, or advisories are in effect for the Florida Keys coastal waters. From synopsis, a surface high will consolidate along the Atlantic coast over the next couple of days. This, along with diurnal influences, should result in slightly freshening northeast to easterly breezes this evening. Winds will slacken some through the remainder of the week as this high tilts eastward and lengthens out into the Atlantic. A new continental high will build as it drive eastward through the eastern United States early next week. This is expected to freshen easterly breezes.
