Synopsis for High Island to the Matagorda Ship Channel out
60 nautical miles including Galveston and Matagorda Bays
1031 AM CDT Fri Jun 14 2024

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

Light to moderate onshore winds and low seas will prevail through
early Sunday. By Sunday afternoon, onshore winds and seas will
begin to gradually build as the gradient steepens between a
developing low pressure system over the Bay of Campeche and an
area of high pressure over the eastern United States. Small Craft
Advisory conditions are possible starting as early as Monday and
continuing until as late as the end of the week. By the middle of
the week, seas could build to 7-10 feet with sustained winds
offshore averaging around 25 knots with gusts over 30 knots. For
now, our forecast keeps conditions under gale criteria. But we
cannot rule out gale conditions, or at least gusts to gale force,
by the middle of the week across the Gulf waters. There will also
be a daily risk of showers and thunderstorms. Rain and
thunderstorms could be heavy at times during the Sunday to
Thursday time frame.

Mariners are advised to monitor the aforementioned low pressure
system. The National Hurricane Center currently estimates that
the system has a 50 percent chance of becoming a tropical
depression by the middle of next week. Stronger winds and building
seas will remain likely even if the system does not develop.
