...BEACH HAZARDS STATEMENT IN EFFECT FROM FRIDAY MORNING THROUGH
LATE FRIDAY NIGHT...

The National Weather Service in Grand Rapids has issued a Beach
Hazards Statement...which is in effect from Friday morning
through late Friday night. 

* HIGH WAVE ACTION... STRONG CURRENTS AND DANGEROUS SWIMMING 
  CONDITIONS EXPECTED.

* STRONG STRUCTURAL CURRENTS EXPECTED.

* STRONG LONGSHORE CURRENTS EXPECTED. 

* RIP CURRENTS EXPECTED. 

* LOCATION...BEACHES FROM St. Joseph to Manistee.
 
  North Beach in South Haven... 
  Holland State Park... 
  Muskegon State Park... 
  Mears State Park in Pentwater... 
  Stearns Park in Ludington. 

* OVERVIEW/POTENTIAL IMPACTS...North winds of 15 to 25 mph Friday
  will cause wave heights to build to 3 to 6 feet. Waves of this
  height will pose a hazard to swimmers.
  

PRECAUTIONARY/PREPAREDNESS ACTIONS...

High Wave Action makes swimming difficult and can tire even a
strong swimmer quickly. 

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.
