Detailed Forecast


Synopsis: An area of high pressure allows for northwest winds to continue through early next week across the eastern gulf. This has also allowed for a marine layer to develop along the eastern gulf coast. For Saturday, strongest winds will be over the SE gulf coast and W to E oriented channels. High pressure over the Gulf continues through early next week, which will bring overall calmer conditions for the inner channels.
