Weather radar is an effective tool for detecting and tracking all forms of precipitation, from rain and snow, to ice pellets and hail, and can provide advance warning of thunderstorms and other hazardous weather.

With a range of 250 kilometres each, Environment Canada’s radar network  which consists of 31 sites, covers regions of Canada that are prone to thunderstorms. These areas are also where 98 per cent of the country’s population lives.

Animated, colour-coded radar images compiled from the latest network data, indicate the location and intensity of precipitation on a national, regional and local scale, and can provide indications of the short-term motion and development of systems.
