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

A brief shower or two may occur this afternoon, but otherwise the
forecast will remain dry. Northeast winds increase tomorrow into
Monday as a broad area of low pressure develops over the central
Gulf. Expect winds around 15 knots with 2-4 foot seas, and if any
stronger winds materialize, small craft will have a need to
exercise caution. Next week, the daily landbreeze/seabreeze
cycle will become dominant as seas also diminish to less than 2
feet.
