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

Showers and thunderstorms can be expected for the next several days over the waters. Coverage should become more widespread in the late week due to a cold front that is expected to move off the coast Thursday night.

Ahead of the front, a long fetch of moderate east to southeast winds will provide somewhat elevated seas and above normal tide levels. Behind the front, moderate to occasionally strong northeast winds can be expected. For much of the week, caution flags are likely and advisories are possible.
