Significant Meteorological Information (SIGMET)

The Canadian weather radar network consists of 31 weather radars spanning Canada’s most populated regions. Their primary purpose is the early detection of precipitation, its motion and the threat it poses to life and property. Each has a range of 256 km (159 mi) in radius around the site to detect reflectivity, and a range of 128 km (80 mi) for detecting velocity patterns (Doppler effect).
