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

* WHAT...Rough choppy surf and a southward flowing longshore
  current, with a moderate risk of dangerous rip currents, exists in
  the surf zone today.

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

* WHEN...Through late tonight.

* IMPACTS...Breezy northerly winds will produce rough surf and a
  moderate southward flowing longshore current today, which can
  push swimmers into deeper water unexpectedly and make them more
  susceptible to dangerous rip currents.

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 THURSDAY NIGHT...

* WHAT...Dangerous rip currents.

* WHERE...Coastal Volusia, Coastal Indian River, Coastal Saint
  Lucie, Coastal Martin, Coastal Brevard Counties.

* WHEN...Through late Thursday night.

* 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.

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.
