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

A Small Craft Advisory is in effect in the bays and Gulf waters through
noon today due to strong northerly winds, rough bay waters, and
elevated Gulf seas. The Advisory may be extended into Monday
afternoon for areas offshore due to potential lingering high
seas. Light northeasterly winds are expected to develop by Monday
night with onshore flow returning by Tuesday. There may be a
window of opportunity for patchy sea fog Tuesday night. A cold
front could push offshore late in the week bringing gusty winds
and building. But there exists much uncertainty in the forecast
later this week.
