...BEACH HAZARDS STATEMENT IN EFFECT FROM LATE TONIGHT THROUGH
TUESDAY MORNING...

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

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

* STRONG STRUCTURAL CURRENTS EXPECTED. 

* STRONG LONGSHORE CURRENTS EXPECTED.

* RIP CURRENTS POSSIBLE.

* LOCATION...BEACHES FROM HOLLAND TO MANISTEE.  

* BEACHES WITH PARTICULARLY DANGEROUS CONDITIONS INCLUDE... 

  South Beach in South Haven... 
  Grand Haven State park... 
  Pere Marquette Park in Muskegon. 

* OVERVIEW/POTENTIAL IMPACTS...South winds will increase to 15 to
  25 mph late tonight through Tuesday resulting in wave heights of
  3 to 5 feet. Strong longshore currents and structural currents
  are expected to continue. South facing piers will be  
  particularly dangerous. Additionally, the high waves will 
  overtop the piers due to high water levels.

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.

* BEACHES WITH PARTICULARLY DANGEROUS CONDITIONS INCLUDE...

All beaches and piers.

* OVERVIEW/POTENTIAL IMPACTS...South winds of 15 to 30 mph will
  shift to the north by Wednesday. This will result in wave
  heights of 3 to 6 feet into Wednesday. Strong longshore currents
  and structural currents are expected to continue. Piers will be
  dangerous. This evening it will be mainly the south side of the
  piers. That changes to the north side for Wednesday. 
  Additionally, the high waves will overtop the piers due to high 
  water levels. 

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.
