MARINE

Issued at 401 PM EDT Sun May 3 2026

Showers and thunderstorms are creating a chaotic wind field for the coastal waters surrounding the Florida Keys. Outside of any convection, the general wind direction is from the north to northeast. Mainly seeing gentle to moderate breezes across the reef tract and Florida Bay. Winds will back to the northwest in advance of a quickly approaching high pressure system. As this high slides across the southeast U.S. and enters the Atlantic, expect winds to clock around to the northeast and briefly surge. Thereafter, as the high continues to move out into the Atlantic, breezes will slacken and become more east to southeast.
