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

Onshore flow is beginning to strengthen, but should remain light
to moderate through today, along with relatively low seas. 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. Caution flags may be needed through early
Friday.
