CHICAGO -- Everyone is encouraged to not swim or enter Lake Michigan waters through this evening. Breezy north winds are creating wave heights of 5 to 8 feet along the Illinois and Northwest Indiana shoreline. This is causing life-threatening waves and currents at area beaches.
Anyone caught in a rip current can quickly pulled away from shore and into deeper water. Rip currents most often occur at low sots or breaks in sandbars.
Hazardous structural currents form along piers where currents and waves flow into the structure. These currents can sweep you into deeper water along the pier.
Exposed beaches are more likely to experience the most significant wave and current impacts. Lighter winds will allow the waves to lessen heading into the holiday weekend.
