Random Weather Facts

Weather warnings are announcements separate from and supplementary to routine forecasts issued to warn of weather conditions that may endanger lives and property. Warnings are broadcast by the media, Weatheradio Canada and by the Coast Guard. Warnings are issued for snowstorms, blizzards, heavy blowing snow, heavy rains, frost, freezing rain, severe thunderstorms and strong winds - according to thresholds established for local and regional public needs. In Vancouver, a warning might be issued for an expected snowfall of 5 cm or more, while in Halifax, a warning would only be issued for 15 cm or more of snow.
