.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.
Onshore winds will continue increase while seas continue to build
through today and into tonight. The highest winds and seas are
expected overnight. Winds of 20-30 KTS and gusts up to 35 KTS and
seas of 6-11 feet can be expected over the Gulf. Bay waters will
be rough with gusts up to 30 knots. Small Craft Advisories for the
bays and Gulf waters will be in effect through Wednesday morning.
In addition, rough surf, elevated water levels along the bays and
coasts, and strong rip currents are expected to result in
hazardous conditions for beachgoers. A cold front pushes offshore
Wednesday, bringing strong northerly winds and elevated seas in
its wake by Wednesday night into Thursday. A Small Craft Advisory
will likely be warranted once again. Gusts to gale force are
possible over the Gulf along with low waters levels in the bay.
Winds and seas Thursday into Friday. However, hazardous marine
conditions could linger well into Thursday.
