<br /> <p>A retail buyer captured sea smoke rising over Lake Superior from Duluth, Minnesota, on Tuesday, December 26.</p><p>Dominic Ricci filmed the scene before he started work at the Duluth Pack Store.</p><p>He told Storyful: "I decided to walk down to the water before starting my day, as I often do. It was very cold that morning; about -18 Fahrenheit, according to my car.</p><p>“When the air is much colder than the water, it creates this amazing ‘sea smoke’, as we call it. It’s a very thick fog that gets really active as the sun rises. It’s one of the most beautiful sights I’ve ever seen!”</p><p>Sea smoke, periodically seen in Duluth, appears when really cold air slides over a warmer expanse of water.</p><p>Temperatures at Duluth harbor on Tuesday plummeted to -17 Fahrenheit and below, the Duluth News Tribune reported</a>.</p><p>The highest temperature in Duluth on Christmas Day was -8 Fahrenheit, according to the local newspaper</a>. This meant it was the fourth-lowest Christmas high temperature on record in the city. Credit: Instagram/Dominic Ricci via Storyful</p><br />
