low pressure over the southwest Gulf of Mexico approaches deep
south Texas. The moderate southeast winds will lead to increasing
swells that will impact the beaches of the Middle Texas coast.
With elevated astronomical tides combined with the moderate

A Coastal Flood Advisory indicates that onshore winds and tides
will combine to generate flooding of low areas along the shore.
Swim near a lifeguard. If caught in a rip current, relax and
float. Don’t swim against the current. If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.
