Coastal Waters Forecast for Texas
National Weather Service Houston/Galveston TX
For High Island to the Matagorda Ship Channel Out 60 NM including Galveston and Matagorda Bays.
Upper Texas coastal waters from High Island to the Matagorda Ship Channel out 60 nautical miles including Galveston and Matagorda Bays. Seas are provided as a range of the average height of the highest 1/3 of the waves.along with the occasional height of the average highest 10 percent of the waves. Light to moderate southwest and southerly winds, 2-4 foot seas, hot, and dry conditions are expected through at least midweek. Mariners should keep tabs on Tropical Depression Two, currently situated in the northeast Gulf, as the week progresses. It is forecast to eventually strengthen into a tropical storm as it approaches southeast Louisiana toward midweek. Beyond that, if it survives the upper shear, some drier air, and closeness to the coast.this system could then make its way westward toward the Texas coast Friday and Saturday. Considerable forecast uncertainty exists and track and intensity changes are subject to change.
