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

A weak front is expected to stall over the Gulf waters this
afternoon, resulting in northeast to easterly winds over the area
with isolated showers. Winds will swing back around to the
southeast during the day Sunday, followed by increasing speeds and
building seas into Monday night. The next weather system will
bring shower and thunderstorm chances back to the region Monday
night and Tuesday, but its associated cold front probably won`t
push off the coast until early Wednesday morning. Small Craft
Advisories will be possible on Wednesday behind the front.
