A warning of dangerous swimming conditions at Lake Michigan beaches from Grand Haven southward is in effect through 2 a.m. Friday.
In a Beach Hazards Statement, the National Weather Service says high wave action, strong currents and dangerous swimming conditions are expected along the shorelines in Ottawa, Allegan and Van Buren counties.
Piers may be heavily swamped by waves.
Strong currents can pull swimmers into deeper water and high waves can sweep people off piers.
Northerly winds at around 25 mph will create 3- to-4-foot waves along the lakeshore. The worst conditions of 3- to-5-foot waves will occur between 4 p.m. and sunset at the North Beach in South Haven and at Holland State Park.
Remain out of the water to avoid hazardous swimming conditions and do not venture out on piers. Check with your local authorities on potential beach closures.
