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

Light northeasterly to easterly winds will become southeasterly
later today. The main impact will be the development of areas of
fog tonight into Sunday morning. Fog could become dense at times.
A Dense Fog advisory might be warranted for later tonight and
Sunday morning. A cold front will push through by Sunday
afternoon. Northerly winds will increase in the cold front`s
wake, likely warranting Small Craft Advisories Sunday afternoon
into Monday morning. Occasional gusts to gale force cannot be
ruled out offshore in the open Gulf. Winds and seas should
gradually improve by Monday afternoon, with onshore flow returning
by Tuesday. May need to monitor the potential for sea fog by the
middle of next week.
