...Swells continue building and moving into the Coastal waters...

.Offshore buoys continues to indicate a long period swell 
continues to build over the Southern Gulf with a long fetch of
moderate to strong southeast winds. This swell will produce higher
surf in the break zone as well as increase the rip current threat
along the area beaches of South Padre Island, Boca Chica and north
along Padre Island of Willacy and Kenedy counties.

...HIGH SURF ADVISORY IN EFFECT UNTIL 8 PM CDT THIS EVENING...
...HIGH RIP CURRENT RISK IN EFFECT UNTIL 8 PM CDT THIS EVENING...

The National Weather Service in Brownsville has issued a High
Surf Advisory, which is in effect until 8 PM CDT this evening. A
High Rip Current Risk has also been issued. This High Rip Current
Risk is in effect until 8 PM CDT this evening. 

* WAVES AND SURF...5 to 7 feet occasional breakers around 8 feet
  near the South Padre Island jetties. 

* TIMING...Now through 8 pm this evening

* IMPACTS...Strong and potentially life threatening rip currents
  and large surf are likely along area beaches. Rip currents and
  pounding rough can be hazardous and life threatening to even 
  experienced swimmers.
  

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A High Surf Advisory means that high surf will affect beaches in
the advisory area...producing localized beach erosion and
dangerous swimming conditions.

There is a high risk of rip currents.

Rip currents are powerful channels of water flowing quickly away
from shore...which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins...
jetties and piers. Heed the advice of lifeguards...beach patrol
flags and signs.

If you become caught in a rip current...yell for help. Remain
calm...do not exhaust yourself and stay afloat while waiting for
help. If you have to swim out of a rip current...swim parallel to
shore and back toward the beach when possible. Do not attempt to
swim directly against a rip current as you will tire quickly.
