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

After a stretch of tranquil marine conditions, a cold front is
expected pass off the coast between 2am-6am Sunday. There will be
some stronger onshore winds before the front, but particularly
higher north winds and building seas after the front passes. Small
Craft Advisory conditions are expected, along with at least some
gusts to gale force. There is some potential for more widespread
gale conditions on the Gulf between late Sunday morning and early
Monday morning. A Small Craft Advisory is in effect for the Bays
late tonight through late Sunday Night. For the Gulf Waters, a
Small Craft Advisory will be in effect late tonight through Sunday
morning, and will likely be upgraded to a Gale Warning that will
be in effect through Sunday night. For now, a gale watch has been
issued for this timeframe. Another potential hazard behind the
front is low water conditions late Sunday and Monday, which will
also be impacted by the strength of the expected winds.
