 .Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
 including Galveston and Matagorda Bays.
 
 In the remaining hours before the front arrives, expect light
 onshore winds, low seas, and even patchy fog redevelopment.
 The front is about to move into the Houston metro, and should be
 pushing into the bays after midnight, and out over the Gulf
 between 3 and 6 am. While light winds and any fog may linger for a
 short while after the front passes, they will scour out shortly
 afterwards as strong, gusty north to northeast winds build in the
 front's wake. Along with the strong winds, building seas will
 follow. Gusts to near gale force are expected on the bays, and
 frequent gusts to or above gale are likely on the Gulf. A Small
 Craft Advisory is in place for the Bays and a Gale Warning on the
 Gulf until late Sunday night. For those working onshore, a wind
 advisory is in place on all islands and peninsulas beyond the
 Intracoastal Waterway as well as Chambers County on Sunday.
 
 Winds and seas gradually diminish Monday morning, and return to a
 southeast direction by Monday night. The quick turn in winds
 should prevent low tides from getting low enough to require a Low
 Water Advisory, but we should still see a few low tide cycles with
 levels around or slightly below MLLW.
