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

East to northeast winds will continue to increase this morning
to around 20 knots with some higher gusts continuing into to mid
morning hours. Water levels will also be running above normal due
in part to the moon phase and existing easterly fetch. Marine
weather conditions will gradually improve later today and through
the weekend. A more predominant onshore flow resumes Saturday
evening and Sunday.
