...HIGH RIP CURRENT RISK IN EFFECT THROUGH THIS EVENING...

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

* TIMING...The threat for strong rip currents will be present all
  day, however the risk will be highest during the afternoon due 
  to tidal effects. 

* IMPACTS...Rip currents will be dangerous and life threatening
  today! Numerous water rescues have occurred over the past  
  several days, with even stronger rip current conditions expected
  today!
  

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.

EVENING...
...HIGH SURF ADVISORY IN EFFECT FROM 5 PM THIS AFTERNOON TO 11 PM
EDT THURSDAY...

The National Weather Service in Melbourne has issued a High Surf
Advisory, which is in effect from 5 PM this afternoon to 11 PM
EDT Thursday. 

* WAVES AND SURF...High surf will develop into late afternoon and
  this evening along the east central Florida beaches and continue
  through tonight into Thursday as large swells from Hurricane
  Florence make their way toward shore. The large and battering
  waves will make entering the surf hazardous for beach goers
  tonight and Thursday. The risk of strong rip currents will also
  continue into late week. 

* TIMING...The threat for strong rip currents will be present all
  day, however the risk will be highest during the afternoon due 
  to tidal effects. High surf is expected by this evening through 
  Thursday at east central Florida beaches.

* IMPACTS...Rip currents will be dangerous and life threatening
  today! Numerous water rescues have occurred over the past
  several days, with even stronger rip current conditions expected
  today! Building surf this evening into Thursday will be
  hazardous to beach goers. The large waves can knock you down and
  make you susceptible to being caught in a rip current.

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. Only 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.

A High Surf Advisory means that high surf will affect beaches in
the advisory area...producing localized beach erosion and
dangerous swimming conditions.
