Radar overview

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.

Environment Canada's radar network consists of 31 sites, which covers regions of Canada that are prone to thunderstorms.

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.
