Need to be alerted when weather threatens? Or do you just want to hear the latest weather information for your area at any time of day or night, any day of the year? Environment Canada’s Weatheradio network broadcasts weather warnings and current observations and forecasts using the VHF public radio band, 24/7. Within range of more than 90 percent of the population, Weatheradio can be heard on special receivers and, in some areas, on ordinary AM/FM radio.
