Mason-Oceana-Muskegon-Ottawa-
1108 AM EDT Sun Aug 18 2019

...BEACH HAZARDS STATEMENT REMAINS IN EFFECT UNTIL 8 PM EDT THIS
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 Holland to Manistee

* Beaches with particularly dangerous conditions include...
  Grand Haven State Park and Pere Marquette Park in Muskegon

* Overview/potential impacts...Southwest winds of 15 to 25 knots
  will build waves into the 3 to 5 foot range this afternoon and
  evening north of Holland. Strong longshore and structural
  currents are both expected. Piers may also be over topped due to
  high lake 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.
