Chicago, IL – Boaters on Lake Michigan are facing hazardous conditions as dense fog and high waves impact the waters near Chicago and Northwest Indiana. A Dense Fog Advisory is in effect until 9 a.m. CST Friday, followed by a Small Craft Advisorybeginning at noon and lasting through the weekend.
According to the National Weather Service (NWS) Chicago, visibility is expected to drop below 1 nautical mile this morning, making navigation difficult from Calumet Harbor, IL, to Michigan City, IN.
