CHICAGO (AP) — The National Weather Service is warning people about dangerously high waves and flooding along the Lake Michigan shoreline.

In Chicago, police say a man died early Saturday after a large wave swept him into the lake at North Avenue Beach. Crews searched for the man for about two hours before finding him. They said waves were as high as 10 feet.

The National Weather Service says a beach hazard warning is in effect through Monday afternoon for areas of Illinois, Indiana and Michigan. They say people visiting beaches should stay out of the water.

High winds are expected to cause strong rip currents and life-threatening waves. Officials also say lakeshore flooding is expected, included on Chicago’s lakefront path.
