NOAA All Hazards Weather Radio


What is NOAA Weather Radio?

NOAA Weather Radio is a free public service of the National Oceanic and Atmospheric Administration. The National Weather Service operates a network of NOAA Weather Radio stations across the country, and there are a handful of these stations in Arizona. Our staff prepares the broadcasts for the Phoenix, Yuma, and Globe radio stations, and the remaining stations in Arizona are handled by offices in Flagstaff and Tucson.

NOAA Weather Radio broadcasts are commercial-free, and operate 24 hours a day, 7 days a week. Routine broadcasts prepared by NWS Phoenix include current weather conditions, local and extended forecasts, Arizona weather summaries, travelers forecasts, and climate summaries.

During severe weather, routine weather programming will be interrupted with special statements and warning messages bringing you up-to-the-minute information on the developing weather situations. In addition, the specially equipped NOAA Weather Radio receivers can sound an alarm when extremely threatening weather is approaching your community. 

The most important feature of NOAA Weather Radio is this capability to tone activate weather radio receivers. This feature can turn on weather radio receivers alerting the listener that severe weather is imminent. The primary mission of the NWS is to issue severe weather warnings to protect life and property. The NOAA Weather Radio ensures consistent "Alarm" service directly to the public, schools, hospitals, day care centers, and commercial broadcasters.


Specific Area Message Encoding (SAME)

Specific Area Message Encoding (SAME) technology allows you to program specially equipped NOAA Weather Radio receivers to sound a warning alarm tone for only specific types of weather events in select geographic areas. For example, a resident of Phoenix could set their NOAA Weather Radio receiver to activate an alarm tone ONLY for tornado and flash flood warnings affecting Maricopa county. Another resident of Casa Grande may wish to set their receiver to receive ANY type of warning, but only those affecting Pinal county. Thus, the SAME system allows you to tailor your weather radio to alert you only to the types of watches or warnings you desire to hear, and only in the geographic area you've chosen.

To take advantage of SAME technology, you must have a specially designed NOAA Weather Radio receiver. For more information on SAME, including SAME codes for any county in the United States, please visit the National SAME page.


How do I tune in?
NOAA Weather Radio broadcasts can not be received on most conventional AM/FM radios; you need a special receiver. These special receivers, which are available from several manufacturers, are available with and without the alerting features discussed above. Some other manufacturers also include the NOAA Weather Radio bands as special features on an increasing variety of receivers. NOAA Weather Radio capability is currently available on some automobile, aircraft, marine, citizens band, and standard AM/FM radios as well as communications receivers, transceivers, scanners, and cable TV. However, if you wish to have the warning alarm feature, your best bet is to purchase a special receiver designed for this purpose.


Where can I buy them?
Special NOAA Weather radios can often be found at many department stores, electronic stores, and online retailers. A number of models and styles are available, and prices usually range from around $25 for a basic receiver to over $70 for an advanced unit. You can generally find a good-quality receiver for around $40 to $50 with a built-in alarm. The National Weather Service does not endorse any particular brand, but we do recommend purchasing one with SAME technology.


Where can I tune in?
By nature and design, NOAA Weather Radio coverage is limited to an area within about 40 miles of the transmitter, but this range will vary somewhat in mountainous regions. A list of transmitting sites in Arizona is provided in the table below. The quality of the broadcast is generally dictated by the distance from the transmitter, the terrain, and the quality and location of the receiver. Varying weather conditions can also affect the quality of the received signal. Sometimes, transmitter problems can result in a degraded or inaudible signal. Click on a location in the table below to see a coverage map for that specific transmitter.
