A weather radio service is a broadcast service which airs special weather-related emergency broadcasts and announcements. Weatheradio services may also broadcast non-weather related emergency information, such as in the event of a natural disaster, an AMBER alert or a terrorist attack. They generally broadcast on a special VHF frequency audible only with special "Weatheradio" receivers or radio frequency scanners, although in some locations a weatheradio broadcast may be retransmitted on a conventional AM or FM frequency, and some television stations broadcasting in MTS stereo transmit weatherradio on their second audio program (or SAP) channel.
Weather radios come with several features that make them very helpful in case of an emergency. Some models use crank power, in addition to eletricity and batteries, which is a life saver in case of an electricity outage or if you are located in an unserviced area (such as a forest). Some models have an embedded flashlight and can double as a cell phone charger.
Weather radios are widely sold in electronics stores in the United States, but in Canada may be only available online, especially in communities without frequent serious weather emergencies (such as Vancouver and Calgary). The price of a weather radio varies depending on the model and its extra features, and can range from $15 to more than $70 in the United States[1] and from $30 to $140 in Canada[2].
