Frigid temps cause Pancake Ice to form along Lake Michigan

CHICAGO (WLS) -- The bitterly cold temperatures have led to peculiar-looking ice formations on Lake Michigan called "Pancake Ice".

The discs of ice began forming Sunday morning all along the city's lakefront.

According to ABC 7 Meteorologist Mark McGinnis, the formations occur when tiny bits of ice begin to rotate in the water. The phenomena is similar to a larger ice disc in Maine that went viral.

McGinnis expects the circles of ice to continue to expand and become a giant sheet of ice by Monday.
