SYNOPSIS FOR KEYS COASTAL WATERS FROM OCEAN REEF TO DRY TORTUGAS
424 PM EDT WED MAY 27 2026
SYNOPSIS
AN ATLANTIC HIGH PRESSURE SYSTEM CENTERED SOUTHWEST
OF BERMUDA WILL CONTINUE TO FLATTEN WHILE SHIFTING FURTHER SOUTH.
THIS WILL ALLOW BREEZES TO FURTHER SLACKEN AND EVENTUALLY SHIFT TO
THE SOUTHEAST AND SOUTH. THIS WILL ALSO ALLOW FOR BETTER MOISTURE
TO BEGIN MOVING IN FROM THE SOUTH AND SOUTHWEST, LEADING TO A
GREATER COVERAGE OF SHOWERS AND THUNDERSTORMS. MOISTURE WILL LIFT
NORTH OUT OF THE AREA LATE THURSDAY WITH RELATIVELY DRIER
CONDITIONS RETURNING FOR THE END OF THE WEEK AND INTO THE WEEKEND.
THIS WILL LIMIT BUT NOT ELIMINATE THE POTENTIAL FOR SHOWERS AND
THUNDERSTORMS.
THE APPROXIMATE SHOREWARD EDGE OF THE GULF STREAM AS OF MAY 22...
22 NM SOUTH OF DRY TORTUGAS LIGHT...ON LOGGERHEAD KEY.
9 NM SOUTH OF COSGROVE SHOAL LIGHT...OFF THE MARQUESAS KEYS.
