...HIGH RIP CURRENT RISK IN EFFECT FROM 7 AM EST THIS MORNING
THROUGH MONDAY EVENING...

The National Weather Service in Tampa Bay Ruskin has issued a
High Rip Current Risk, which is in effect from 7 AM EST this
morning through Monday evening. 

* RIP CURRENT TIMING...Increasing wave action will create rip
  currents today and Monday.

* RIP CURRENT IMPACTS...Life threatening Rip Currents are likely 
  to continue through late tonight. 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.
