  to 1 to 2 feet overnight. A high swim risk is expected this
  afternoon and early evening south of Grand Haven. North sides
  of north piers will be dangerous places to swim given longshore
  currents intersecting the piers in these locations creating
  strong structural currents along them. Stay dry when waves are
  high.

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.

A Lakeshore Flood Advisory indicates that onshore winds will
generate flooding of low areas along the lakeshore.
