...COASTAL FLOOD ADVISORY NOW IN EFFECT UNTIL 4 PM EST TUESDAY...
...BEACH HAZARDS STATEMENT IN EFFECT FROM 7 AM EST THIS MORNING
THROUGH THIS EVENING...

* WHAT...For the Coastal Flood Advisory, minor coastal flooding.
  For the Beach Hazards Statement, strong southward flowing
  longshore current and 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 Tuesday. 
  For the Beach Hazards Statement, from 7 AM EST this morning 
  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...Above normal high tides will continue
  through early this week. The highest of the high tides cycles 
  will occur during the morning hours around 8:00 AM to 9:00 AM 
  today, and around 9:00 AM to 9:30 AM Tuesday.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Onshore winds and above normal tides will combine to generate
flooding of low areas along the shore. Do not drive around
barricades or through water of unknown depth. Take the necessary
actions to protect flood-prone property.

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.
