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

A long fetch of 20 to 30 knot south-southeast winds will continue across the western Gulf, producing elevated seas. This will continue through the weekend and Small Craft Advisories remains in effect. Chances for showers and storms will increase ahead of a strong cold front expected to push off the coast Saturday afternoon or evening. Strong northwesterly winds will develop behind the front and persist through Sunday morning causing the Small Craft Advisories to likely be extended. There is potential for some gusts near gale force behind the front going into Sunday morning. Mariners can also anticipate some minor coastal flooding along Gulf facing beaches around times of high tide through Saturday evening.
