...HIGH RIP CURRENT RISK IN EFFECT FROM LATE TONIGHT THROUGH
THURSDAY EVENING...

The National Weather Service in Tampa Bay Ruskin has issued a
High Rip Current Risk, which is in effect from late tonight
through Thursday evening. 

* RIP CURRENT TIMING...Increasing onshore winds and wave action
  will create dangerous rip currents along area beaches late 
  tonight through Thursday evening. 

* RIP CURRENT IMPACTS...Life threatening Rip Currents are likely
  later tonight through Thursday evening. Always swim near a 
  lifeguard, and never swim alone!

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 groins...
jetties and piers. For maximum safety...swim near a lifeguard.
Pay attention to flags and signs.

If you become caught in a rip current...yell for help. Remain
calm...do not exhaust yourself and stay afloat while waiting for
help. If you have to swim out of a rip current...swim parallel to
shore and back toward the beach when possible. Do not attempt to
swim directly against a rip current as you will tire quickly.
