GMZ005-101515- Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas 504 AM EDT Thu Oct 10 2024 .SYNOPSIS...Hurricane Milton continues to move away from the area and is about to emerge back out over Atlantic east of the Space Coast. Breezes have come down substantially through the night and will continue to slacken through today. All Tropical Warnings have been discontinued, replaced by a Small Craft Advisory. While these advisories will likely come down in the not to distant future, they may be required again for the eastern Florida Straits due to an incoming northerly swell. Surface high pressure will move across the Tennessee Valley and then off the Southeast Coast over the weekend and into early next week. As a result, expect gentle to moderate northeast to east breezes through the weekend. However, there may be a period of moderate to fresh breezes Friday and Friday night for the offshore Gulf waters.
