Lake Effect Snowstorms and Their Impact

The Great Lakes act as snow factories each year, especially in November and December, due to the temperature difference between warm lake waters and cold Canadian air. This leads to significant snowfall in regions known as snow belts, particularly around Lakes Erie and Ontario. These lakes are shallow and oriented in a way that maximizes moisture pickup, resulting in heavy snowfalls. Extreme lake effect snowstorms can occur, as seen in 2014 and 2022, causing significant snowfall and even fatalities. The video explains these phenomena and their impacts on surrounding areas.
