...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...Strong rip currents will be possible all day but will 
  be maximized near the time of low tide early this morning and in
  the late afternoon to early evening.

* IMPACTS...Long period swells from Tropical Storm Leslie will
  continue to reach the east central Florida beaches today and
  through most of the work week. These swells will contribute to 
  a high risk of rip currents with strong and dangerous rip 
  currents and dangerous surf likely at east central Florida 
  beaches. Rip currents can be life- threatening.
  

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.
