The National Weather Service in Melbourne has issued a Beach
Hazards Statement for rough surf and dangerous rip currents, 
which is in effect through this evening.

* HAZARDS...Rough surf and rip currents. 

* TIMING...Strengthening east winds will lead to increasingly
  rough surf today, while the threat of rip currents will be 
  greatest through mid afternoon due to tidal effects.

* LOCATION...All the beaches of east central Florida. 

* POTENTIAL IMPACTS...Rough surf can knock you down and make you
  susceptible to rip currents.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If you choose to enter the water, only swim near a lifeguard and
never swim alone! 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.
