...BEACH HAZARDS STATEMENT WILL EXPIRE AT 4 PM CDT THIS
AFTERNOON...

The Beach Hazards Statement is set to expire at 4pm as 
winds and waves have weakened. However, tonight winds and waves
will pick back up and shift slightly more to the northeast. This
will likely bring a high swim risk back into effect later tonight
into Friday morning and possibly into the afternoon for the Lake 
Michigan beaches along Sheboygan, Ozaukee, Milwaukee, Racine and 
Kenosha Counties. Waves of 3 to 5 feet are expected again during 
this period thus another Beach Hazards Statement will likely be 
needed.
