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

Look for increasing onshore winds as the next weather system moves
into the region from the west. With a long fetch of moderate
winds, seas will build tonight into Friday...likely reaching Small
Craft Advisory criteria later on Thursday. As this system moves
in, mariners should expect increasing shower and thunderstorm
coverage...first near the Matagorda waters this evening and
overnight...then overspreading the remainder of the upper Texas
coast Thursday and Friday. The precipitation will probably come in
waves and storms could be strong at times. This system will pass
to the east Friday night followed by improving conditions over the
weekend. The next front is forecast to move into the waters
Monday or Monday night.
