What Does it Take to Trigger a Snowfall Warning in Canada?


It’s interesting to note that Environment Canada believes in and promotes discrimination. i.e. They have a different set of rules for different parts of the country (when it comes to issuing weather warnings).

In terms of snowfall amounts, a mere 5 cm forecast for Vancouver will trigger a warning while 20cm of forecast snow is required in the far northwest corner of the province.

Up in northern Quebec, they’re even tougher where Environment Canada does not issue snowfall warnings at all. The Quebec Inuit are apparently the toughest people in the country… or perhaps they know that the traditional methods of reading the weather are still more accurate than the highest powered computer in the nation crunching numbers down in Ottawa.

Here is the map for the entire nation. Note that areas in white do not receive forecasts and warnings of any kind because they are uninhabited.
