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

The remains of a stalled front will continue to bring scattered
showers and thunderstorms to the region today. Some of the
stronger storms will be capable of producing locally heavy
rainfall and gusty winds. Since expectations are that the better
potential for storms today will be closer to the coast, these
storms could impact the coastal waters as well, particularly the
bays and nearshore Gulf. Winds outside of storms will generally
be light and variable, while becoming erratic and gusty in and
around any storms. Rain chances decrease significantly by the
middle of the week, while winds and seas are expected to remain
rather light/low.
