GMZ300-122045- Synopsis for High Island to the Matagorda Ship Channel out 60 nautical miles including Galveston and Matagorda Bays 254 AM CDT Sun May 12 2024 .Synopsis For High Island to the Matagorda Ship Channel Out 60 NM including Galveston and Matagorda Bays. Moderate to occasionally strong east winds and seas of 3 to 5 feet are expected to persist through at least this evening, and potentially even deeper into the night. Small craft will need to proceed with caution. Shower and thunderstorm activity is anticipated to gradually increase into Monday. While showers and storms will be possible both today and tomorrow, it currently appears that more activity will be over land today, and a bit more potential for storms over the waters on Monday. Tuesday should give us a short stretch of fairer weather and a brief amount of offshore flow, but onshore winds return quickly Tuesday night. This will be followed shortly by the next window for showers and storms in the mid-to-late week. $$ GMZ335-122045- Galveston Bay- 254 AM CDT Sun May 12 2024 ...Small Craft Should Exercise Caution... .TODAY...East winds around 15 to 20 knots, becoming southeast late this morning and afternoon.
