The world's lake-effect snow hot spots might surprise you Caroline Floyd lundi, 21 octobre 2019 à 18:15 - Lake-effect snow is a winter feature in every part of Canada, from sea to sea to sea. Thanks to our unique geography and plentiful coastline, lake-effect snow is a winter fact of life for many Canadians. Whether it's 5-cm-per-hour snowfall rates off of Lake Huron, streamers from the Gulf of St Lawrence, or Strait of Georgia squalls on Vancouver Island, Canada has a lot to offer when it comes to lake- and sea-powered snow. While we do have an ample supply of the key ingredients -- cold air moving over large bodies of warm water -- Canada isn't the only place on the globe that fits the bill. And some of the spots that share in the shovelling might surprise you.
