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

Wind and sea conditions continue to improve as high pressure
settles into region. On Galveston Bay, however, the low water
situation is not improving as we head 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.
