...HIGH RIP CURRENT RISK IN EFFECT FROM 10 AM EST THIS MORNING
THROUGH THIS EVENING...

The National Weather Service in Tampa Bay Ruskin has issued a
High Rip Current Risk, which is in effect from 10 AM EST this
morning through this evening. 

* RIP CURRENT TIMING...Increasing wave action will create more
  frequent and strong rip currents later this morning through
  this evening.

* RIP CURRENT IMPACTS...Strong rip currents will be hazardous for
  those in the surf zone along area beaches.

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.
