...HIGH RIP CURRENT RISK IN EFFECT FROM 7 AM EDT THIS MORNING
THROUGH THIS EVENING...

...MINOR BEACH EROSION DURING TIMES OF HIGH TIDE...

* COASTAL FLOODING...Minor Beach erosion will occur due to wave
  runup to the dune line around the times of high tide. Minor 
  tidal flooding is possible in the more vulnerable flood prone 
  areas.

* TIMING...Life threatening rip currents will be present all day.
  High tide will occur around 8 am and again around 8 pm which 
  will produce minor beach erosion. 

* IMPACTS...Large, long period swells will propagate into the surf
  zone and produce rough surf and a High Risk of strong rip 
  currents, posing a threat to all levels of swimmers. Entering 
  the surf is not advised.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
