...beach hazards statement in effect from tuesday morning through
late tuesday night...
the national weather service in grand rapids has issued a beach
hazards statement...which is in effect from tuesday morning
through late tuesday night.
* high wave action... strong currents and dangerous swimming
conditions expected.

* location...beaches from st. joseph to manistee
* beaches with particularly dangerous conditions tomorrow include...
north beach in south haven...holland state park...muskegon
state park...mears state park in pentwater...stearns park in
* overview/potential impacts...north winds will increase to 15 to
25 knots early tuesday...producing 3 to 5 foot waves and
dangerous currents. the winds and waves will subside from north
to south tuesday evening.
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.
