* Overview/potential impacts... northwest winds 20 to 35 mph will
decrease this evneing. Waves in the 6 to 10 foot range will be
hazardous for swimming. In addition, water temperatures have
dropped off, and could add another hazard to anyone swimming in
the waters of Lake Michigan today.

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.
