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

* TIMING...The threat for life-threatening rip currents will be
  present all day, however, the risk will be particularly high
  this morning through 10:00 AM, and again late this afternoon 
  due to the outgoing tide.

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.
