Because of its location, Barrie, Ontario, Canada is pummeled by an odd weather phenomenon during the winter which causes abnormally high levels of precipitation. What is this phenomenon called?

Lake-effect snow. Barrie, Ontario is north of the Nottawasaga Valley, so in turn, it's part of the southwestern Ontario snowbelt north of Toronto. Lake-effect snow occurs when large bodies of water create bands of precipitation over a concentrated area. In this case, the snow is provided by three of the five Great Lakes: Michigan, Superior, and Huron. Since Barrie is next to Georgian Bay, it's the ideal location for winters of snowsqualls and blizzard-like conditions as well as pleasant, beach-filled summers. Barrie, Ontario is on the shores of Kempenfelt Bay and Lake Simcoe, located forty minutes from Toronto and a few miles from cottage country. Mapped by Kyleisalive.
