623 AM CST Sun Nov 9 2025
.Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
including Galveston and Matagorda Bays.
Expect strengthening northerly winds and building seas in the wake
of this morning's cold front. There is only a slight chance of
showers and thunderstorms over the Gulf waters along the front.
Small Craft Advisory conditions are expected on all area waters
for much of this morning, becoming gales on the Gulf towards mid-
day and through the night. The strong north winds will also
generate low water conditions late Sunday and Monday on both
Galveston Bay and Matagorda Bay, with more severe low water
conditions anticipated on Galveston Bay, where a low water
advisory has been issued. These conditions are expected to be an
issue at low tide on Sunday, but also in upper portions of the bay
and the Houston Ship Channel through Monday's low tide cycle as
well.
