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

Beginning tonight, we will transition to a more persistent 
onshore flow pattern lasting into the weekend. Seas should be 3 
feet or less for most of the work week, but gradually increase to 
around 4 feet on Friday into the early part of the weekend as the 
more persistent fetch sets up. Wind speeds late Friday into
Saturday may approach the caution flag threshold in the Gulf
waters. Rain chances return as early as Thursday morning and 
remain through Sunday when a weak cold front approaches the area.
