...BEACH HAZARDS STATEMENT IN EFFECT FROM 7 AM CDT THIS MORNING
THROUGH SATURDAY AFTERNOON...

The National Weather Service in Milwaukee/Sullivan has issued a
Beach Hazards Statement for dangerous swimming conditions...Which
is in effect from 7 AM CDT this morning through Saturday
afternoon. 

* HIGH WAVE ACTION... Large waves and dangerous currents are 
  expected. Conditions are life threatening.

* STRONG STRUCTURAL AND LONGSHORE CURRENTS ARE EXPECTED. RIP 
  CURRENTS ARE POSSIBLE.

* LOCATION...Beaches from Racine to Kenosha. Beaches with 
  particularly dangerous conditions include... 

     Zoo Beach in Racine...

     Wind Point Lighthouse Beach in Racine...

     Southport Park Beach in Kenosha...

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Structural currents form along piers where longshore currents and
wave action flow into the structure.  Structural currents can
sweep you out into deeper water along the pier structure.

A Longshore current is a lake current that moves parallel to
shore.  Longshore currents can be strong enough to prevent
swimmers from being able to keep their feet on the bottom, making
it difficult to return to shore.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in
sandbars. Rip currents can sweep you into deeper water.
