.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 gale watch has been issued for this timeframe,
and as confidence in just how strong the post-frontal winds are
expected to be, it will be converted to either a small craft
advisory or a gale warning accordingly. 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.
