Beach Hazards Statement Lake Michigan
PRECAUTIONARY/PREPAREDNESS ACTIONS…
Life threatening waves and currents are expected at the beaches.
People visiting the beaches should stay out of the water.
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.
Structural currents form along piers where longshore currents and
wave action flow into the structure. Structural currents can
sweep you into deeper water along the pier structure.
Exposed beaches are more likely to experience the most
significant wave and current impacts. Impacts at beaches with
protective breakwalls or jetties will be subject to the
orientation of structures as well as wind and wave direction.
