GMZ005 Synopsis Issued: 414 AM EDT Wed Apr 15 2026

Synopsis...
A High Pressure System Over The Central North Atlantic Will Maintain Moderate Northeast To East Breezes (Except Moderate To Occasionally Fresh Florida Straits) Today And Tonight. Occasional Fast- Moving Light Showers Cannot Be Ruled Out, Especially In The Overnight Periods. Breezes Likely Will Lull From Late Morning Into The Late Afternoon Across The Gulf/Bayside Waters Due To The Heating Of South Florida. As The High Moves Farther Eastward And Slowly Weakens, Easterly Breezes Will Slacken Thursday Through Sunday. A New High Pressure Will Slide Eastward Sunday Night Into Monday, Allowing For Another Round Of Freshening Breezes. The Approximate Shoreward Edge Of The Gulf Stream As Of April 10... 16 Nm South Of Dry Tortugas Light...On Loggerhead Key. 21 Nm South Of Cosgrove Shoal Light...Off The Marquesas Keys. 23 Nm South Of Sand Key Light...Off Key West. 37 Nm South Of Looe Key...Off Big Pine Key. 29 Nm Southeast Of Sombrero Key Light...Off Marathon. 18 Nm Southeast Of Alligator Reef Light...Off Islamorada. 13 Nm Southeast Of Molasses Reef Light...Off Key Largo. 9 Nm Southeast Of Carysfort Reef Light...Off Ocean Reef.
