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

Persistent low seas and generally light to occasionally moderate winds
driven by the daily seabreeze and landbreeze cycle prevail.
Expect daily opportunities for isolated to scattered showers and
thunderstorms over the next several days as well. Stronger winds
and rougher seas can occur in the vicinity of any thunderstorms.
In some cases, thunderstorm winds can extend far from the
associated storm. Late in the week, winds may increase modestly,
pushing seas more into the 2 to 3 foot range.
