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

Areas of inland fog may bleed into portions of Galveston Bay and
the northern Houston Ship Channel overnight causing reduced
visibility. Through the night, locations near Morgan`s Point seem
to be getting the most impact per webcams and satellite. Fog
should burn off toward mid morning. Areas of fog look to be
possible again Wednesday night, though not as prevalent as
tonight. Otherwise, light to moderate onshore flow should continue
through Thursday night with Gulf seas of 2 to 4 feet. A very weak
frontal boundary will sag close to the coast late Friday night or
Saturday morning then wash out. Onshore winds quickly resume late
in the day Saturday then increase Sunday.
