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

A broad area of low pressure over the southwestern Gulf of Mexico
will bring unsettled weather to the Gulf waters through much of this
week. Look for increasing winds, seas, and water levels across the
upper Texas coastal waters over the next few days. With the
exception of Galveston Bay, a Tropical Storm Watch is in effect due
to the broad. Even though the center of the potential storm should
remain well to our south, an expansive wind field stretches well
north of this system. Small Craft Advisory remains in effect for
Galveston Bay, but some gusts above 30 knots are possible at
times. Water levels will be rising and would anticipate some
coastal flooding in the bays and along the beaches. Small craft
should consider remaining in port until weather conditions start
improving later this week.
