.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 over the coastal locations and Gulf
waters into the evening and overnight hours. Some of the stronger
storms will be capable of producing locally heavy rainfall and
gusty winds. 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 and
low.
