Weather officials said waves up to 6 feet and dangerous currents are expected at beaches Thursday in northern and central Cook County.
A beach hazard is in effect through Friday night as conditions will be life-threatening for swimmers, especially inexperienced swimmers, officials said.
Emergency responders pulled two bodies from Lake Michigan on Labor Day. And another woman who was pulled from the lake near Montrose Harbor in the overnight hours of Tuesday morning also died, officials said.
A man has remained missing since Tuesday morning after officials said he went into the water from a boat offshore near the 31st Street Harbor.
