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

Winds and seas are continuing to subside to more gentle
conditions. Northeasterly winds continue into early Tuesday, with
onshore flow returning for the afternoon. There is a small
probability for patchy sea fog Tuesday night before a front moves
through Wednesday night. A better potential for sea fog may come
over the weekend ahead of the next front in the line - though
there is not a lot of confidence in a specific scenario at this
long range.
