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

Light to occasionally moderate onshore flow and low seas will
prevail through Tuesday. As patchy fog develops inland for the
next couple of nights, some of that fog may drift across the upper
portions of the Bays during the late night to early morning
hours. The onshore flow is expected to strengthen late Wednesday
into Thursday ahead of an approaching cold front, and Small Craft
Advisories may be needed.
