WEATHERADIO

A 'weatheradio' 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, although in some locations a weatheradio broadcast may be retransmitted on a conventional AM or FM frequency.
Notable weatheradio services include:

★ United States - NOAA Weather Radio All Hazards

★ Canada - Weatheradio Canada
