 .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.
