Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas

.SYNOPSIS...The Florida Keys will remain in a col region through
this afternoon. This will promote mainly light to gentle
southeast breezes, occasionally becoming variable. Thereafter, a
weather system will move out of the ArkLaTex region and into the
Southeast U.S. by this evening. The attendent cold front will
sweep through Monday night with a brief period of moderate to
fresh breezes. The potential exists for a more active weather
pattern as the front stalls out across the Straits of Florida for
most of the week.
