Watches & Warnings

Beach Hazard Statement
Issued: 3:39 PM EDT Sep. 25, 2018 – National Weather Service

... Beach hazards statement remains in effect from midnight EDT
tonight through Wednesday 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 Manistee.

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

* Overview/potential impacts... a strong cold front will pass
through the area around midnight turning winds to the
northwest and 15 to 25 mph with gusts to 35 mph. Winds will
turn more westerly by mid morning Wednesday. Those strong
winds will result in 5 to 8 foot waves creating dangerous
conditions for swimmers. In addition, water temperatures have
dropped off, and likely will become even colder yet due to the
mixing by the strong winds. That will add yet another hazard
to anyone swimming in the waters of Lake Michigan Wednesday.

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.
