60 nautical miles including Galveston and Matagorda Bays
203 PM CDT Sun Jun 30 2024

.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 Bay of Campeche will bring a
longer period swell into the upper Texas coastal waters today then
diminish Monday. Otherwise, this system is expected to push
inland into Mexico on Monday with no other impacts locally.
Surface high pressure moving overhead will result in light winds
and a more distinct landbreeze/seabreeze circulation through
Tuesday. More prevalent onshore winds will resume by midweek.
