...BEACH HAZARDS STATEMENT IN EFFECT FROM 2 AM EDT TUESDAY
THROUGH LATE TUESDAY NIGHT...

The National Weather Service in Grand Rapids has issued a Beach
Hazards Statement...which is in effect from 2 AM EDT Tuesday
through late Tuesday night. 

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

* STRONG STRUCTURAL CURRENTS EXPECTED.

* STRONG LONGSHORE CURRENTS EXPECTED. 

* RIP CURRENTS POSSIBLE. 

* 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...NORTH WINDS WILL INCREASE TONIGHT
  IN THE WAKE OF A COLD FRONT TO 15 TO 25 KNOTS. THESE WINDS WILL
  CONTINUE INTO TUESDAY AFTERNOON AND EVENING. WAVES WILL BUILD
  INTO THE 3 TO 5 FOOT RANGE LATE TONIGHT. THE WAVES MAY BRIEFLY
  SUBSIDE TO 2 TO 4 FEET TUESDAY MORNING BEFORE BUILDING AGAIN TO
  3 TO 6 FEET TUESDAY AFTERNOON AND EVENING. STRONG LONGSHORE
  CURRENTS ARE EXPECTED SWEEPING DOWN THE BEACH FROM NORTH TO
  SOUTH. STRONG STRUCTURAL CURRENTS ARE EXPECTED ON THE NORTH SIDE
  OF NORTH PIERS. RIP CURRENTS ARE ALSO POSSIBLE. 

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.
