.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.
Recent wind data offshore suggest seas will be slow to decrease
today. With winds expected to increase again this evening and
tonight, we opted to issue a Small Craft Advisory due to hazardous
seas for the offshore Gulf waters through Friday morning. Showers
and thunderstorm activity will diminish later this afternoon.
However, we expect an increasing chance of thunderstorms once
again late tonight through Friday morning. The forecast for the
weekend into early next week features light to moderate onshore
flow and a continued daily risk of showers and thunderstorms.
Higher winds and waves can be expected in the vicinity of any
thunderstorm.
