Island TX out 60 nautical miles including Sabine and

246 PM CDT Sat Jun 15 2024

.SYNOPSIS...
Weak high pressure will bring about mainly light easterly winds
into Sunday. A trough will gradually move west across the
southern Gulf of Mexico from early to mid week. Deep moisture will
be associated with this system that will bring widespread shower
activity. The gradient between the trough and high pressure to the
northeast will bring moderate to strong east to southeast winds at
or above 20 knots by Monday, that will continue through mid week.
This prolonged wind field will allow for a significant increase in
wave heights and swells. Small craft advisories will likely be
needed during this period. Also, tides will be 1 to 2 feet above
normal predicted levels that may lead to coastal flooding.
