000 FZNT25 KNHC 202012 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 412 PM EDT Wed Sep 20 2023 ...Please refer to Coastal Waters Forecasts (CWF) available through NOAA Weather Radio and other means for detailed Coastal Waters Forecasts... Southeast Gulf of Mexico .SYNOPSIS...High pressure will be in control of the weather pattern across the Gulf waters allowing for generally gentle to moderate east to southeast winds and slight seas, except pulsing to moderate to fresh offshore the western Yucatan Peninsula in the evenings. Developing low pressure east of Florida will tighten the pressure gradient over the NE Gulf bringing moderate to locally fresh NE winds across the NE Gulf Thu night into Fri. A frontal trough associated with the aforementioned low pressure will move across the SE Gulf and the Straits of Florida Thu night into Fri. .TONIGHT...NE to E winds 10 to 15 kt. Seas 2 ft or less. Scattered showers and isolated tstms. .THU...NE winds 5 to 10 kt. Seas 2 ft or less. .THU NIGHT...NE winds 10 to 15 kt. Seas 2 ft or less. .FRI...NE winds 10 to 15 kt.

Seas 3 ft in the morning, subsiding to 2 ft or less. .MON NIGHT...E to SE winds 5 to 10 kt. Seas 2 ft or less. Within 200 nm east of the coast of Florida .SYNOPSIS...Marine conditions continue to improve over the NE waters as Hurricane Nigel moves far away from the forecast area. A stationary front extending from just south of Bermuda to NE Florida will lift northward on Fri as low pressure develops along it to the east of northern Florida, where frequent gusts to gale force are possible Thu night into Fri. This non-tropical area of low pressure could acquire some subtropical characteristics on Friday while it moves generally northward. Regardless of development, this low is likely to bring gusty winds to gale force, heavy rain, and high surf to portions of the Southeast and Mid-Atlantic United States late this week and into this weekend. .TONIGHT...E winds 10 to 15 kt.
