...HIGH RIP CURRENT RISK IN EFFECT FROM 2 PM EDT THIS AFTERNOON
THROUGH WEDNESDAY EVENING...

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

* RIP CURRENT TIMING...Increasing wave action will create rip
  currents from 2 PM this afternoon through 11 PM Wednesday.

* 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
