.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM

Moderate onshore winds will continue through the next few hours

showers and thunderstorms are expected to reach the bays very late

Some of the storms could be on the strong side. Moderate to strong
north winds can be expected in the wake of the front, and Small

Another upper level disturbance will move through Sunday night and
Monday bringing another round of rain and embedded thunderstorms.
