NOAA Weather Radio (NWR) is a nationwide network of radio stations broadcasting continuous weather information direct from a nearby National Weather Service office. NWR broadcasts National Weather Service warnings, watches, forecasts and other hazard information 24 hours a day.
Working the Federal Communications Commission's new Emergency Alert System (EAS), NWR is an "all hazards" radio network, making it the single source for the most comprehensive weather and emergency information available to the public. NWR now broadcasts warning and post-event information for all types of hazards - both natural (such as earthquake and volcano activity) and technological (such as chemical releases or oil spills).
Known as the "Voice of the National Weather Service," NWR is provided as a public service by the Department of Commerce's National Oceanic and Atmospheric Administration. The NWR network has more the 450 transmitters, covering the 50 states, adjacent coastal waters, Puerto Rico, the U.S. Virgin Islands and the U.S. Pacific Territories. NWR requires a special radio receiver or scanner capable of picking up the signal. Broadcasts are found in the public service band between 162.400 and 162.550 megahertz (MHz).
