.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.
Moderate onshore winds and isolated to scattered showers and
thunderstorms are anticipated today through Saturday. A weak
front is expected to push into the waters late Saturday night into
Sunday morning. After a brief wind shift to the north and
northeast, winds will swing back around to the southeast by
Monday. This shift in winds will not result in significant changes
to wave heights, but may result in confused seas until the return
of onshore winds has been persistent enough to keep more
consistent wave directions.
