GMZ300-151615- Synopsis for High Island to the Matagorda Ship Channel out 60 nautical miles including Galveston and Matagorda Bays 1051 PM CDT Fri Jun 14 2024 .Synopsis For High Island to the Matagorda Ship Channel Out 60 NM including Galveston and Matagorda Bays. Winds and seas will increase over the next several days as the pressure gradient tightens while a long fetch sets up over the Gulf of Mexico. Ample Gulf moisture will bring numerous showers/storms daily, beginning on Sunday. Small Craft advisories could be needed by early next week as winds approach 15 to 20 knots and seas reach 4 to 7 feet. An area of low pressure is expected to develop over the Southwestern Gulf of Mexico/Bay of Campeche by mid week. This system is currently expected to track west to northwesterly into Mexico later in the week. However, winds over the Texas coastline are still expected to reach 20 to 25 knots by Wednesday with seas rising to 7 to 10 feet. Winds and seas could possibly be higher depending on how this system tracks. Mariners are advised to monitor the aforementioned low pressure system. The National Hurricane Center currently estimates that the system has a 50 percent chance of becoming a tropical depression by the middle of next week. Stronger winds and building seas will remain likely even if the system does not develop. $$ GMZ335-151615- Galveston Bay- 1051 PM CDT Fri Jun 14 2024 .REST OF TONIGHT...Southeast winds 5 to 10 knots.
