.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.

Shower and thunderstorm chances increase today as some deeper
tropical moisture moves into the area. Tropical Depression Two should
move inland over the southern coast of Mexico later today, will
not pose an issue to the upper Texas coast other than a very slight
increase in seas. Beyond Monday, mostly light to moderate onshore
winds and 2 to 4 foot seas are expected, along with a daily risk
of isolated to scattered showers and thunderstorms.
