...BEACH HAZARDS STATEMENT IN EFFECT THROUGH THIS EVENING...
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 4 PM EST THIS
AFTERNOON...

* WHAT...For the Coastal Flood Advisory, minor coastal flooding.
  For the Beach Hazards Statement, strong southward flowing
  longshore current and a Moderate Risk for rip currents.

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

* WHEN...For the Coastal Flood Advisory, until 4 PM EST this 
  afternoon. For the Beach Hazards Statement, through this 
  evening.

* IMPACTS...Some flooding of low-lying lots, parks and roadways
  may occur near the shoreline around times of high tide. At area
  beaches, a strong southward flowing longshore current will exist
  today, which can knock swimmers off the sandbar into deeper 
  water and make them more susceptible to rip currents.

* ADDITIONAL DETAILS...The highest of the high tides cycles today
  will occur during the morning hours, around 9:00 AM to 9:30 AM.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Onshore winds and above normal tides will combine to generate
minor flooding of low areas along the shore. 

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.
