...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...The greatest threat for strong rip currents will be
  through late morning and again late this afternoon due to tidal
  effects. 

* IMPACTS...When the rip current risk is high, the surf is
  dangerous for all levels of swimmers. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

There is a high risk of rip currents today. 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.
