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

Light to occasionally moderate onshore winds and 2 to 4 foot seas
will prevail through the middle of next week, along with a
continued daily risk of isolated to scattered showers and
thunderstorms. However, a system passing well to the south is
expected to bring higher rain chances on Sunday into Monday, along
with somewhat higher winds and seas. We could not rule out seas
offshore approaching Small Craft Advisory threshold during that
time. For now, the forecast keeps seas below 7 feet.
