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

Look for east northeast winds to increase late tonight and prior
to sunrise as the pressure gradient tightens. We will probably see
somewhat elevated winds and building seas continue into early
afternoon...followed by somewhat a decrease in the late afternoon
and early evening. Speeds will again increase Thursday night into
Friday. Water levels will also be running above normal due to the
winds, seas, and moon phase. Marine conditions will gradually
improve late Friday through the weekend. A more predominant
onshore flow resumes Saturday night and Sunday.
