...BEACH HAZARDS STATEMENT IN EFFECT FROM 10 AM CDT THIS MORNING
THROUGH EARLY THIS EVENING...

The National Weather Service in Milwaukee/Sullivan has issued a
Beach Hazards Statement for dangerous swimming conditions...Which
is in effect from 10 AM CDT this morning through early this evening. 

* 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 Sheboygan to Ozaukee County. Beaches 
  with particularly dangerous conditions include... 

     General King Park Beach in Sheboygan...

     Kohler-Andrae State Park Beaches...

     North Beach in Port Washington...

     South Beach in Port Washington...

     Harrington State Park Beaches...

     Atwater Beach in Milwaukee...

     Bradford Beach in Milwaukee...

     North Beach in Racine...

     Zoo Beach in Racine...

     Sam Myers Beach in Racine...

     Wind Point Lighthouse Beach in Racine...

     Eichelman Beach in Kenosha...

     Southport Park Beach in Kenosha...

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Dangerous pounding waves and life-threatening currents are
expected at the beaches.  People visiting the beaches should stay
out of the water.

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.

...BEACH HAZARDS STATEMENT WILL EXPIRE AT 7 PM CDT THIS EVENING...

Wave heights are expected to remain on average between 1 and 4
feet at Lake Michigan beaches from Sheboygan to Kenosha the rest 
of the night. Hence the Beach Hazard Statement will be allowed to
expire at 7 pm.  

Developing northeast winds late tonight and Saturday morning will
cause wave height to build to 3 to 5 feet on Saturday resulting in
a High Swim Risk returning to the area.
