...BEACH HAZARDS STATEMENT IN EFFECT FROM MIDNIGHT EDT TONIGHT
THROUGH TUESDAY AFTERNOON...

The National Weather Service in Grand Rapids has issued a Beach
Hazards Statement...which is in effect from midnight EDT tonight
through Tuesday afternoon. 

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

* STRONG STRUCTURAL CURRENTS POSSIBLE.

* STRONG LONGSHORE CURRENTS POSSIBLE.

* RIP CURRENTS EXPECTED. 

* LOCATION...BEACHES FROM St. Joseph to Pentwater.

* BEACHES WITH PARTICULARLY DANGEROUS CONDITIONS INCLUDE... 

 North and South Beach in South Haven...
 Holland State Park... 
 Muskegon State Park...
 Mears State Park in Pentwater...

* OVERVIEW/POTENTIAL IMPACTS...West winds will be the increase
  later tonight and through Tuesday morning leading to wave
  heights building into the 3 to 5 foot range. 
  

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.
