...HIGH RIP CURRENT RISK IN EFFECT FROM 8 AM EDT THIS MORNING
THROUGH THIS EVENING...
...HIGH SURF ADVISORY IN EFFECT FROM 10 AM THIS MORNING TO 8 AM
EDT WEDNESDAY...

The National Weather Service in Melbourne has issued a High Surf
Advisory, which is in effect from 10 AM this morning to 8 AM EDT
Wednesday. A High Rip Current Risk has also been issued. This
High Rip Current Risk is in effect from 8 AM EDT this morning
through this evening. 

* WAVES AND SURF...Breaking waves of 5 to 7 feet will occur within
  the surf zone. 

* TIMING...Swells will build in height all day.

* IMPACTS...Noticeably large breaking waves will make entering the
  water hazardous. Strong Rip Currents will also be present within
  the surf zone. 
  

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A High Surf Advisory means that high surf will affect beaches in
the advisory area...producing localized beach erosion at high tide
along with very dangerous swimming conditions.

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. If you must enter the water, heed the advice of 
lifeguards...beach patrol flags and signs.

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.
