8 PM THIS EVENING...

* WHAT...Dangerous rip currents expected.

* WHERE...Southern Brevard, Indian River, St. Lucie, Martin,
  Coastal Volusia and Northern Brevard Counties.

* WHEN...From 8 AM this morning through 8 PM this evening. While
  rip currents will be present all day, the threat will be

* IMPACTS...Rip currents can sweep even the best swimmers away

* ADDITIONAL DETAILS...Be sure to check with local officials

  county or community.

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.

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.
