An area of low pressure over the southern Gulf of Mexico is
expected to move north into the northwest Gulf of Mexico by Sunday
afternoon. This will lead to a strong pressure gradient
maintaining a moderate to strong northeast flow Saturday night
through Monday. This will lead to higher waves over the Gulf
waters and increase the tide levels along the middle Texas coast.
With astronomical high tides occurring in early November... minor
coastal flooding is likely around the time of high tide along the
middle Texas coast Saturday night through Sunday night. Tide
levels are expected to be 1 to 1.5 feet above normal... or 2 to 2.5
feet above mean sea level causing flooding of area beaches.
It is possible that tide levels could be even higher by Sunday
night... resulting in moderate coastal flooding. If moderate
coastal flooding is expected... then a coastal Flood Watch or
warning may be required later this weekend.
In addition to the coastal flooding... high swells will lead to
dangerous rip currents developing along the coast for the
weekend. Rip currents can be life threatening even to experienced
swimmers and surfers.
Precautionary/preparedness actions...
Swimming and other marine-related activities are highly
discouraged due to the threat from heavy surf and rip currents.
Heavy surf and rip currents pose a danger to anyone in the water.
If you are caught in a rip current... do not panic. Escape the
current by swimming in a direction following the shoreline until
you are free from the rip current.
Listen to NOAA Weather Radio or your local media for the later
updates on this situation... as a coastal Flood Watch may be
required later today or this weekend.
