GMZ300-231515- Synopsis for High Island to the Matagorda Ship Channel out 60 nautical miles including Galveston and Matagorda Bays 904 PM CDT Sun Sep 22 2024 .Synopsis For High Island to the Matagorda Ship Channel Out 60 NM including Galveston and Matagorda Bays. Light to occasionally moderate onshore flow will continue over the next few days with isolated streamer showers possible. Winds across the marine area will gradually back from southeast to northeast by mid week...ahead of a cold front and on the NW fringe of a large cyclonic circulation developing over the Gulf. The passage of the cold front...will lead to winds shifting to the north and increasing...possibly to caution or even advisory levels by Thursday. As the cold front pushes through...a low pressure system...likely a tropical storm or hurricane...will be lifting north across the Eastern Gulf. The track of the storm should be well east of the marine forecast area...although will lead some increase in seas due to long period swell being generated by the hurricane...and will also contribute to the increase in the north winds. $$ GMZ335-231515- Galveston Bay- 904 PM CDT Sun Sep 22 2024 .TONIGHT...Southeast winds 5 to 10 knots.
