including Galveston and Matagorda Bays.

Lowering winds and decreasing seas can be expected though today.
Generally moderate onshore flow and somewhat elevated seas are
anticipated this week and into the start of the weekend. Caution
flags might occasionally be needed during periods of higher winds,
especially Wednesday night into Thursday. Periods of unsettled
weather are possible, though better shower and thunderstorm
chances should be situated a bit further inland for much of the
forecast period as the next cold stays away from the coast.
