Elevated winds and elevated seas will prevail into Sunday

early Sunday morning for Matagorda Bay, and through Sunday
afternoon for the Gulf waters. The advisory for the Gulf waters
will likely be extended into Sunday night. Winds will be more
east-northeasterly to northeasterly through tonight as the low

to exit the area. Expect widespread rain showers with embedded
thunderstorms through Sunday afternoon. Light onshore flow
resumes late Monday. We`ll continue to monitor the potential for
some periods of sea fog late Tuesday into Wednesday night until
the next front pushes off the coast.
