...HIGH RIP CURRENT RISK IN EFFECT THROUGH THIS EVENING...

The National Weather Service in Houston/Galveston has issued a
High Rip Current Risk, which is in effect through this evening. 

* TIMING...Through this evening.

* IMPACTS...Hazardous swimming conditions. Beachgoers should 
  exercise caution if entering the water and only swim in areas 
  with lifeguards on duty.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

There is a high risk of rip currents. Life threatening rip
currents are likely in the surf zone.
               
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. Swim near a lifeguard.
               
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.

...High Rip Current Risk has Subsided...

.Lower winds and surf have diminished the overall threat of strong 
rip currents. That being said, do not swim near rocks, jetties and 
piers. Regardless of how calm things might appear, there are almost 
always rip currents near those features.
