Beach Hazard Statement
Issued: 3:46 PM EDT Jul. 17, 2018 – National Weather Service

... Beach hazards statement in effect until 2 am EDT Wednesday...

The National Weather Service in Grand Rapids has issued a beach
hazards statement... which is in effect until 2 am EDT Wednesday.

* 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 and Holland State Park.

* Overview/potential impacts... north winds of 20 to 25 knots will
continue into this evening. Waves of 3 to 6 feet will also
continue into this 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.
