60 nautical miles including Galveston and Matagorda Bays
332 AM CDT Fri Apr 4 2025

.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
Sunday morning.
