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

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

* TIMING...While potential life-threatening Rip Currents will be
  present all day, the risk will be highest through 1030 AM, and
  again after 5 PM due to tidal effects.

* IMPACTS...Numerous strong Rip Currents in the surf zone will
  post a threat to swimmers today. Weak swimmers may not to enter
  the water above their knees today. Always swim within sight of 
  a lifeguard, never swim alone.
  
  

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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 jetties and
piers. Heed the advice of lifeguards...beach patrol flags and
signs.

Swim near a lifeguard. If caught in a rip current, relax and
float. Don't swim against the current. If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.
