.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.
A cold front will move offshore this evening, resulting in strong
north winds reaching around 30 knots with higher gusts as it
pushes offshore. This has resulted in a Small Craft Advisory
beginning at 9 PM tonight and remaining in effect through tomorrow
morning. The potential for Gale conditions still cannot totally
be ruled out and an upgrade to a Gale Warning might be required.
Conditions will begin to diminish on Thursday, and onshore winds
will return by Friday morning. Onshore winds look to remain just
below caution thresholds throughout the weekend.
