...HIGH RIP CURRENT RISK IN EFFECT UNTIL 2 PM EDT THIS
AFTERNOON...

The National Weather Service in Tampa Bay Ruskin has issued a
High Rip Current Risk, which is in effect until 2 PM EDT this
afternoon. 

* RIP CURRENT TIMING...Increasing wave action will create rip
  currents through this afternoon.

* RIP CURRENT IMPACTS...Rip currents can sweep even the best 
  swimmers away from shore into deeper water. Southward moving 
  longshore currents can also move swimmers quickly parallel to 
  the beach.

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.
