What was once Hurricane Sandy is being felt on Lake Michigan, where lingering high winds are causing the southern part of the lake to swell.

Listen:

Dave Benjamin with the Great Lakes Surf Rescue Project says the lake is a similar to a big bath tub, with a weather system that has essentially forced a windy cold front to rest over Lake Michigan.

Benjamin says those winds are pushing the bulk of the water in the lake to the south, causing water levels to swell. Benjamin says it will then move back to the north, which could cause beach erosion and other problems close to shore.

The Indiana Department of Natural Resources predicts that waves will be more than three times larger than usual on Lake Michigan.
