...BEACH HAZARDS STATEMENT IN EFFECT THROUGH LATE TONIGHT...

* WHAT...A strong southward flowing longshore current is 
  expected in the surf zone.

* WHERE...Volusia, Brevard, Indian River, Saint Lucie and Martin
  Coasts.

* WHEN...Through late tonight.

* IMPACTS...North to northeast winds 20 to 25 mph will produce a
  strong southward flowing longshore current at the beaches, 
  which can knock swimmers off their feet or into deeper water, 
  making them more susceptible to dangerous rip currents. The 
  longshore current will also increase the risk of rip currents 
  near piers and jetties.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

...HIGH RIP CURRENT RISK IN EFFECT THROUGH LATE TONIGHT...

* WHAT...Dangerous rip currents.

* WHERE...All central Florida Atlantic beaches.

* WHEN...Through late tonight.

* IMPACTS...Rip currents can sweep even the best swimmers away
  from shore into deeper water.

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.
