GMZ300-160915- Synopsis for High Island to the Matagorda Ship Channel out 60 nautical miles including Galveston and Matagorda Bays 306 PM CDT Sat Jun 15 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 storms daily, beginning on Sunday. Small Craft advisories will be needed early next week as a coastal trough sets up near the Texas coastal, bringing strong winds of 20 to 30 knots with gusts in excess of Gale-Force possible. Seas are expected to reach 7 to 11 feet at times. These strong onshore winds over a long fetch will also bring a high risk of rip currents and potentially some coastal flooding across the Texas coastline as early as Tuesday. An area of low pressure is expected to develop over the Southwestern Gulf of Mexico/Bay of Campeche by mid week. While this system is currently expected to track west to northwesterly into Mexico later in the week, there is much uncertainty. Forecasted winds and seas may vary drastically depending on how this system evolves. Stay tuned over the next several days as we monitor this possible system. $$ GMZ335-160915- Galveston Bay- 306 PM CDT Sat Jun 15 2024 .TONIGHT...Southeast winds 5 to 10 knots.
