Environment Canada operates a network of weatheradio transmitters that broadcast continuous weather information--current conditions, forecasts, plus severe weather watches and warnings . There are about 170 of these transmitters across Canada, and over 90 percent of Canadians live within range of one of them.
Broadcasts can usually be heard within 60 km of each transmitter. Our weatheradio transmitters hang on towers like this one, sharing space with other organizations like regular radio stations and communications companies.
Weatheradio messages are broadcast on special VHF frequencies that allow a warning tone to be transmitted when hazardous weather is approaching. That's why you can't hear the signal on an ordinary AM/FM radio. The frequencies most commonly used in Canada are 162.40, 162.475, and 162.55 MHz.
If your weatheradio receiver is equipped with the "tone alert" feature, the warning tone will actually turn your receiver on, so that you don't miss the bulletin.
Weatheradio receivers come in all shapes and sizes--they're available from many electronics stores. You can choose a portable model or one for the desk top. The most important feature, though, is the tone alert option, so that you'll know when severe weather is on the way.
