.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 has set up
across the western Gulf and are producing elevated seas. This will
continue through at least Saturday morning and Small Craft
Advisories are 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. Mariners
can also anticipate some minor coastal flooding along Gulf facing
beaches around times of high tide through Saturday morning.
