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

A Low Water Advisory and a Small Craft Advisory remain in effect
this morning due to moderate to strong northeast winds. Winds will
relax this afternoon and remain moderate through early Thursday.
However, an area of low pressure is expected to move up the Texas
Coast on Thursday, bringing strong winds and rough seas along
with moderate to occasionally heavy rain. Hazardous marine
conditions are likely to continue in the wake of the low on Friday
due to strong northwesterly winds, continued rough seas, and the
potential for low water levels at the coast and in the bays.
Conditions improve Friday night into Saturday.
