...BEACH HAZARDS STATEMENT IN EFFECT FROM 4 AM CDT MONDAY THROUGH
MONDAY MORNING...

The National Weather Service in Milwaukee/Sullivan has issued a
Beach Hazards Statement for dangerous swimming conditions...Which
is in effect from 4 AM CDT Monday through Monday morning. 

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

* STRONG STRUCTURAL CURRENTS...Expected

* STRONG LONGSHORE CURRENTS...Expected

* RIP CURRENTS...Expected

* LOCATION...Beaches around Sheboygan. Beaches with particularly 
  dangerous conditions include... 

     General King Park Beach in Sheboygan...

     Kohler-Andrae State Park Beaches...

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.

...BEACH HAZARDS STATEMENT WILL EXPIRE AT NOON CDT TODAY...

Southeast winds of 10 to 20 mph will keep waves elevated in the 2
to 4 foot range this afternoon, so a moderate swim risk is still
expected. 

A moderate swim risk means that breaking waves and currents are
expected. Stay away from dangerous areas like piers, breakwalls,
and river outlets. Always have a flotation device with you in the
water.
