A breezy northwest flow will pull in cooler air, creating high waves along the lakefront. According to the National Weather Service, a Lakeshore Flood Advisory is in effect until 4 p.m. Thursday for Cook County and until midnight for Porter and Lake counties in Indiana.

In Cook County, waves could be as high as 5 to 8 feet. Northwest Indiana beaches could see waves of 8 to 12 feet. This could cause some lake shore flooding and beach erosion, but the waves should subside by Thursday night.
