.Synopsis for Jupiter Inlet to Ocean Reef FL out to 60 nm and for
East Cape Sable to Bonita Beach FL out to 60 nm...

Atlantic waters as winds will continue to enhance and northeasterly
swell increases. This may result in a period of hazardous conditions
during the early week period, this will be monitored over the next
couple of days. A few isolated showers are possible across the
Gulfstream waters through the overnight and possibly into Sunday.
Gulf Stream Hazards: None.
