...HIGH RIP CURRENT RISK IN EFFECT FROM 8 AM EDT THIS MORNING
THROUGH THIS EVENING...

* WHAT...Dangerous rip currents expected. Rough surf with breaking
  waves 4 to 6 feet will remain a hazard in the surf zone. 

* WHERE...Coastal Volusia County.

* WHEN...From 8 AM EDT this morning through this evening.

* IMPACTS...Rip currents can sweep even the best swimmers away
  from shore into deeper water. Moderately large breaking waves
  can knock you down and make you even more susceptible to
  becoming caught in the seaward pull of a rip current. Rough surf
  from breaking waves of 4 to 6 ft may cause minor beach erosion 
  around the time of high tide this afternoon. 


PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
