...HIGH RIP CURRENT RISK IN EFFECT UNTIL 7 PM EST THIS EVENING...

The National Weather Service in Miami has issued a High Rip
Current Risk, which is in effect until 7 PM EST this evening. 

* TIMING...Through this evening

* IMPACTS...Strong rip currents may cause hazardous swimming
  conditions.

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 groins, 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.
