...BEACH HAZARDS STATEMENT IN EFFECT FROM 2 PM EDT THIS AFTERNOON
THROUGH THIS EVENING...

The National Weather Service in Grand Rapids has issued a Beach
Hazards Statement...which is in effect from 2 PM EDT this
afternoon through this evening. 

* 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 Grand Haven. 

* BEACHES WITH PARTICULARLY DANGEROUS CONDITIONS INCLUDE... North
  Beach in South Haven... Holland State Park...

* OVERVIEW/POTENTIAL IMPACTS... Winds from the northwest will
  increase in strength today. Waves and currents will increase
  during the afternoon and subside after sunset. Waves of 3 to 5
  feet pose a hazard to swimmers. Water temperatures are still  
  in the 50s and this will create a risk of cold water shock to 
  those diving or falling into the water.
  

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.
