...BEACH HAZARDS STATEMENT IN EFFECT THROUGH THIS EVENING...

* WHAT...Strong northward flowing longshore current and a moderate
  risk of life-threatening rip currents expected.

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

* WHEN...Through this evening.

* IMPACTS...A strong northward flowing longshore current will 
  exist today at area beaches, which can knock swimmers off the 
  sandbar into deeper water 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.
