* WHAT...Rough Surf and a High Risk of life threatening rip
  currents expected.

* WHERE...Volusia, Brevard, Indian River, St. Lucie and Martin 
  Counties.

* WHEN...From 7 AM EDT this morning through Friday evening.

* IMPACTS...Dangerous swimming conditions in the surf zone today

  sweep even the best swimmers away from shore into deeper water.

* ADDITIONAL DETAILS...Entering the surf is not recommended.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
