Beach Hazard Statement
Statement as of 3:23 PM EDT on August 23, 2016
Expires 2:00 AM EDT on August 25, 2016
... Beach hazards statement remains in effect through late
* high wave action... strong currents and dangerous swimming
* Strong structural currents expected.
* Strong longshore currents expected.
* Rip currents possible.
* Location... beaches from South Haven to Manistee.
Beaches on the south side of piers will be particularly
dangerous. This includes Grand Haven State Park and Pere
Marquette Park in Muskegon.
* Overview/potential impacts... south winds of to 15 to 25 knots
will continue into Wednesday night. This will cause waves of 3
to 6 feet into Wednesday night.
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.
