An area of low pressure over the southern Gulf of Mexico is
expected to move north into the northwest Gulf of Mexico by late
Sunday. This will lead to increasing east to northeast flow
through Sunday with a strong northeast flow developing by late
Sunday afternoon across the offshore waters. The low will
eventually merge with Tropical Storm Ida as it moves into the
northern Gulf Coast early next week.
The combination of the western Gulf low and Ida will lead to
higher waves over the Gulf waters and increasing long period
swell. This will increase the tide levels along the middle Texas
coast. Minor coastal flooding is likely around the time of high
tide along the Texas coast especially Sunday and Sunday night.
Tide levels are expected to be around 1 foot above normal... or
2 to 2 1/2 feet above mean sea level on the beach side of the
barrier islands. This will cause minor flooding of area beaches.
The next high tide at Port Aransas will occur at 952 PM CST this
evening... and at 418 am CST Sunday morning at Port O'Connor. The
peak water levels will likely occur with the high tide Sunday
evening.
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.
Driving on area beaches is discouraged as water levels could rise
trapping vehicles on the beach during high tide.
Listen to NOAA Weather Radio or your local media for the latest
updates on this situation... as a coastal Flood Watch may be
required later depending on the progress of Tropical Storm Ida as
it moves into the Gulf.
