...HIGH SURF ADVISORY NOW IN EFFECT UNTIL 3 AM EST TUESDAY...
...HIGH RIP CURRENT RISK IN EFFECT FROM THIS MORNING THROUGH THIS
EVENING...

The National Weather Service in Melbourne has issued a High Rip
Current Risk, which is in effect from 6 AM EST this morning
through this evening. 

* WAVES AND SURF...A low pressure off the mid-Atlantic coast will
  continue to produce large breaking waves and dangerous surf
  through tonight. In addition, strong rip currents are expected 
  today at east central Florida beaches. 

* TIMING...Large breaking waves will remain present in the surf
  zone through Monday night. Numerous strong rip currents are
  expected today, especially this morning through 9 am and again
  after 3 pm.

* IMPACTS...Minor beach erosion is likely during times of high
  tide through Monday night. The timing of the high tides are noon
  and then between midnight and 100 am. High surf and strong rip 
  currents will be present within the surf zone. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A High Surf Advisory means that high surf will affect beaches in
the advisory area, producing localized beach erosion and 
dangerous surf conditions. Entering the water is not recommended.

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.
