...HIGH RIP CURRENT RISK IN EFFECT UNTIL 8 PM EDT THIS EVENING...

The National Weather Service in Melbourne has issued a High Rip
Current Risk, which is in effect until 8 PM EDT this evening. 

* TIMING...The greatest threat for strong rip currents will be
  through the morning hours into early afternoon due to tidal
  effects.

* IMPACTS...When the rip current risk is high, the surf is
  dangerous for all levels of swimmers. In addition, breezy
  onshore winds today will produce rough surf along the coast. 

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.
