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

Light to moderate onshore flow and seas of 3 to 6 feet are expected
through mid next week, warranting caution flags at times, especially
during the overnight hours. Rounds of showers and storms will be
possible into the weekend, with rain chances tapering off next week.
Some of these storms could become strong to severe, producing
damaging wind gusts and locally elevated seas. Persistent onshore
flow will bring a high risk of rip currents into the upcoming
work week.
