.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.
Poor marine conditions continue for Galveston Bay with low water
conditions expected to continue into a stretch of very low
astronomical tides. The low water advisory has been extended
through Thursday, and may need to continue even later. Light and
variable winds tonight will gradually become more southwesterly
through Wednesday, continuing through Friday. Eventually, humidity
will increase enough that patchy fog will be possible during the
overnight hours Thursday night and Friday night, but there is
still considerable uncertainty in how significant fog development
will be.
