...HIGH SURF ADVISORY IN EFFECT UNTIL 9 PM CDT THIS EVENING...
...HIGH RIP CURRENT RISK IN EFFECT UNTIL 9 PM CDT THIS EVENING...

The National Weather Service in Brownsville has issued a High
Surf Advisory, which is in effect until 9 PM CDT this evening. A
High Rip Current Risk has also been issued. This High Rip Current
Risk is in effect until 9 PM CDT this evening. 

* WAVES AND SURF...6 to 10 feet.

* TIMING...through 9 pm tonight. 

* IMPACTS...Large waves breaking near the shoreline with some wave
  washing over portions of the South Padre Island Jetties. Some
  overwash of tides during high tide (4 pm) sending water near the
  dune line. 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.
