View weather radar animations and prognostic charts for Canada. Doppler radar images are provided by Environment Canada and prognostic charts are provided by NAV CANADA. Canada Weather is location-aware and can automatically find the closest radar station. You can also select from a list of 31 stations nationwide, including five regional views: Pacific, Prairies, Ontario, Quebec, and Atlantic. New in version 2. 0 are the Surface Analysis and Graphical Area Forecast (GFA) charts. The Surface Analysis is a snapshot of the current pressure and frontal systems across Canada. GFAs give you a 12 hour forecast of the expected pressure and frontal systems at a regional level, along with information such as expected precipitation, cloud height and coverage, turbulence, icing, and freezing level.
