931 FZNT25 KNHC 152034 OFFN04 NAVTEX Marine Forecast NWS National Hurricane Center Miami, FL 434 PM EDT Sat Jun 15 2024 ...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...A surface trough extends from the Florida Big Bend region to the eastern Bay of Campeche this afternoon. The NE portion will shift NW and dissipate tonight. A broad low to middle level cyclonic circulation, a Central American Gyre, is centered over the south-central Gulf of Mexico and extends into Central America. This feature is expected to become better organized through Mon, as it drifts westward. Environmental conditions appear conducive for a tropical cyclone to develop from this broad area of low pressure, and a tropical depression could form over the southwestern Gulf during the middle part of next week, then move west or west-northwestward. Active convection across the southeast Gulf, along with increasing winds and building seas, is expected to shift westward with this system into the middle part of next week, significantly impacting the south-central and northwest Gulf. .TONIGHT...SE winds 15 to 20 kt.
