...BEACH HAZARDS STATEMENT IN EFFECT THROUGH THIS EVENING...
...HIGH RIP CURRENT RISK IN EFFECT THROUGH THIS EVENING...

The National Weather Service in Melbourne has issued a Beach
Hazards Statement for Rough Surf, which is in effect through this
evening. A High Rip Current Risk has also been issued through 
this evening. 

* HAZARDS...Large breaking waves up to 5 to 6 feet. Numerous
  strong Rip Currents in the surf zone.

* TIMING...Threats will be in place all day. The surf will be at
  its roughest around high tide through late morning. Rip Currents
  will tend to be more frequent from a little before 12 noon until
  about 530 PM.

* LOCATION...the central Florida Atlantic beaches from Flagler
  Beach to Jupiter Inlet.

* IMPACTS...Large breaking waves can knock you down and  make you
  even more susceptible to becoming caught in the seaward pull of
  a rip current.

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.

There is a high risk of rip currents.

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.

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.
