.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM including Galveston and Matagorda Bays.

A moderate onshore flow will generally continue through the week. Small craft operators will need to exercise caution at times. Rip currents will likely remain moderate to strong at times, while water levels are expected to be near 3.0 feet above Mean Lower Low Water during high tide cycles over the next few days. A cold front and an associated chance of showers and thunderstorms will push offshore late Saturday into early Sunday. Strong offshore winds and increased seas will likely prompt the issuance of Small Craft Advisories by late this weekend.
