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

 PRECAUTIONARY/PREPAREDNESS ACTIONS...

If you do decide to enter the water today, swim only within sight
of a lifeguard. If caught in a rip current, relax and float. Don't
swim against the current. If able, swim in a northward direction 
following the shoreline. Do not try to swim south to escape a rip 
current today, as you will be swimming directly into the long 
shore current! If unable to escape, face the shore and call or 
wave for help.
