.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.
Another couple rounds of fog are expected tonight into mid-late
morning Saturday, then again Saturday night into early Sunday
morning as warmer air overspreads the cooler waters. Fog may become
dense at times. Light onshore winds and low seas will generally
prevail until the next cold front and associated scattered showers
and isolated thunderstorms pass through the bays prior to sunrise
Sunday. This will bring an end to the fog threat, but gusty north
and northeast winds and building seas will fill in behind the
front. Gusts close to gale are possible in the Gulf. Winds and
seas gradually diminish Monday morning, and return to a southeast
direction by Monday night.
