About NOAA Weather Radio
NOAA Weather Radio, the "Voice of the National Weather Service", provides continuous broadcasts of the latest weather information from the Tulsa National Weather Service office 24 hours a day, 365 days a year.

To receive the broadcasts, you need a special radio capable of receiving signals in the VHF band. In Eastern Oklahoma, Northwest Arkansas and far Southwest Missouri, 162.475, 162.500 and 162.550 MHz are the frequencies for the NOAA Weather Radio broadcasts. Please refer to the table below for specific county information.

Weather messages are repeated every 3 to 5 minutes and are routinely updated every 1 to 3 hours or more frequently in rapidly changing local weather or if a nearby hazardous environmental condition exists.

During severe weather, Tulsa National Weather Service personnel can interrupt the routine broadcasts and insert special warning messages concerning imminent threats to life and property. In an emergency, each transmitter is capable of transmitting a warning alarm tone and the new Specific Area Message Encoding (SAME) signal, followed by information on the emergency situation. These signals will activate specially designed receivers, either increasing the volume or producing a visual and/or audible alarm. Not all weather band receivers have this capability, but all radios that receive NOAA Weather Radio can receive the emergency broadcasts.

NOAA Weather Radio is directly available to approximately 70 to 80 percent of the U.S. population. The National Weather Service is currently engaged in a program to increase coverage to 95 percent of the population. Unfortunately, NOAA Weather Radio remains a vastly underused service and resource.

For the general public, travelers and outdoor enthusiasts, NOAA Weather Radio provides unequaled means of obtaining the latest weather information available as well as the quickest source for warnings of natural hazards.

Frequently Asked Questions

1. What is NOAA Weather Radio?

NOAA Weather Radio (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from a nearby National Weather Service (NWS) office. NWR broadcasts NWS warnings, watches, forecasts and other hazard information 24 hours a day.

Working with the Federal Communications Commission's new Emergency Alert Systen (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 earthquakes 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 National Weather Service, a component of the Department of Commerce's National Oceanic & Atmospheric Administration (NOAA). The NWR network has more that 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 found in the public service band between 162.400 and 162.550 MHz.

2. Where can I get a NOAA Weather Radio?

NOAA Weather Radio receivers come in a vareity of sizes, styles and prices and can usually be found in electronic stores (such as Radio Shack) across the country. You can also purchase NOAA weather radios online at www.noaaweatherradios.com.

3. How much does a NOAA Weather Radio cost?

NOAA Weather Radios range in cost from around $20 up to $100 or more depending on the quality of the receiver and number of features.

4. What types of NOAA Weather Radio receivers are available?

NOAA Weather Radio receivers come in many sizes with a variety of functions. Many radios can receive an alarm tone, triggered when the NWS issues severe weather announcements or emergency information. Most NWR receivers are either battery-operated portables or AC-powered desktop models with battery backup, so they can be used in many different situations. Some CB radios, scanners, short wave and AM/FM radios are also capable of receiving NWR transmissions.

5. What frequencies are used for NOAA Weather Radio broadcasts and how can I get a list of the frequencies for my state?

The seven NWR broadcasts frequencies are 162.400 MHz, 162.425 MHz, 162.450 MHz, 162.475 MHz, 162.500 MHz, 162.525 MHz and 162.550 MHz. NWR coverage is expanding through NWS partnership programs with local communities. For the latest list of frequencies and transmitter locations, check the NOAA Weather Radio web site.

Broadcast range from the weather radio transmitter is approximately 40 miles. The effective range depends on terrain, quality of the receiver and indoor/outdoor antennas. Before you buy a receiver, make sure your area is covered by one the transmitters.

6. What features should I look for in a NOAA Weather Radio?

There are several features to look for in a NOAA Weather Radio. The most desirable feature is an alarm tone or a radio capable of receiving the new EAS digital code. This allows you to have the radio turned on but quiet, listening for a special tone that is broadcast before watch and warning messages. During an emergency, National Weather Service forecasters will interrupt routine radio programming and send out a special tone that activates the NOAA Weather Radios in the listening area.

The new generation of NWR receivers allows you to pre-select the National Weather Service alerts you want to receive according to local geographical areas (counties or in some cases portions of counties). Look for NWR receivers with the SAME feature (Specific Area Message Encoding) which means the receiver is capable of turning itself on from a silent mode when the digital code is broadcast before the alarm tone is sounded for the geographic area you have pre-selected.

In addition, a good receiver should be able to operate on batteries during times when electrical services may be interrupted. Look for radios with an AC adapter and battery compartment. The radio should be tunable or switchable to all seven NWR frequencies. Some older models receive only three frequencies which will not work in all locations.

7. I just purchased a NOAA Weather Radio with the SAME feature -- where can I get the specific geographic code I need to program my receiver?

The NOAA Weather Radio web site offers a list of the SAME codes for all U.S. states and surrounding territories. A toll-free number (1-888-NWR-SAME or 1-888-697-7263) is available so that radio owners can get the SAME codes and should be operating by the fall. A table of counties with the corresponding FIPS codes for Eastern Oklahoma, Northwest Arkansas and far Southwest Missouri can be found below.

8. Can I get NOAA Weather Radio broadcasts in my car?

Several automobile manufacturers (BMW, Mercedes, Range Rover and Saab) equip their cars with radios capable of receiving NWR broadcasts. Several manufacturers of car radios (Audiovox, Clarion and Panasonic) sell in-dash units capable of receiving NWR broadcasts.

Manufacturers of citizen band radios with NWR channels include Cobra, Maxon, Midland, Radio Shack and Uniden.

9. I live in an area where I can't get NOAA Weather Radio tranmissions. Is there another system in place for me to get forecasts, watches and warnings directly from the National Weather Service?

The National Weather Service works in partnership with media outlets across the country to get the most current and accurate weather information to the public. Tune in to your local radio and television stations for the latest weather forecasts, watches and warnings. NWS products and services are also available on the National Weather Service Internet site which also includes links to individual forecast offices. Delivery of data across the Internet, however, cannot be guaranteed because of potential interruption of service.

Another low-cost method for receiving National Weather Service's (NWS) essential information in now available on a wireless data system. Called the Emergency Managers Weather Information Network, or EMWIN, this system presents the information directly on your home or office computer in an user-friendly graphics display. Simple mouse clicks immediately retrieve the latest weather and flood warnings, watches, forecasts, statements, observations and other data in text format, along with a sub-set of weather graphics including the national radar summary, and some satellite imagery. In all, over 6500 products are available. Users may set various alarms to be alerted to particular information, whether for their local area or from adjacent areas.

The EMWIN weather information is free; the only cost is for the receiving equipment and inexpensive commercial software. This digital datastream is available nationwide directly from several satellites and, in an increasing number of locations, in an easier and less costly manner using local radio re-broadcasts and other techniques. This approach provides the necessary redundancy for reliable data reception by a wide variety of users.

EMWIN was designed to be a low-speed (currently 1200 bits per second, but expected to increase), low-cost alternative for emergency management officials and others that have no access to weather data or have few resources to afford such data. (Even at this current low speed, over 5000 pages of information can be received each day). It was not designed, however, to replicate such other existing weather dissmination systems as NOAA Weather Radio (NWR).

For more information about EMWIN, visit the EMWIN web site.

10. How can I help my community get NOAA Weather Radio broadcasts?

The goals of the National Weather Service and emergency preparedness agencies is to expand the reach of weather radio broadcasts to cover 95 percent of the U.S. population. Innovative partnerships between the NWS, private industry, and state and local governments are fueling this expansion. You can help foster such partnerships in your community. For more information concerning developing partnership with the NWS, contact the Tulsa National Weather Service office at 918-838-7838.

11. My NOAA Weather Radio often turns on when the forecast office issues watches and warnings that don't impact me. What can I do about that?

With the addition of the Specific Area Message Encoding (SAME) technology, life-saving messages broadcast on NWR can now be targeted to a more specific area, like a county or portion of a county, to bring more hazard-specific information to the listening audience. While older models of weather radio receivers will continue to work, to take full advantage of the specific area warnings technologies, you will need to get a state-of-the-art receiver with digital SAME capabilities for receiving geographically specific warnings.

12. I live in one county and work in another -- will the SAME programmable NOAA Weather Radio receivers be able to alert me for more than one county?

The capability to program the SAME-capable NOAA Weather Radio receivers for multiple counties is available on the new Radio Shack receiver and also on a commercial quality receiver sold by INH Technologies of Fort Worth, TX. If this feature is important, be sure to check for its availability in whatever brand of SAME-capable receiver you examine.

13. Do you have a similar program for communicating warnings to the hearing and/or visually impaired?

The hearing and visually impaired can also get these warnings by connecting a specially-designed weather radio to other kinds of attention-getting devices like strobe lights, bed-shakers, personal computers and text printers. Many pager companies now offer alerting pagers that provide the latest weather information.

14. Where can these items be purchased?

Some NWR receivers have a connector on the back to control all sorts of remote control devices such as flashing lights or other attention-getting devices. Check with electronics stores, electronics catalogs or conduct an Internet search for more details. Pager companies can give you information on weather-related information products as well.

15. Are there any new developments under way for the NOAA Weather Radio network?

Several developments are under way. First, the NWS continues to work with local communities, businesses and non-profit organizations to install NOAA Weather Radio transmitters in areas of the nation not currently served by NWR broadcasts.

Second, the NWS expects to begin installing a new automated broadcasting system in local NWS offices. These personal computer-based broadcasting consoles automatically turn written NWS forecasts and warnings into synthesized-voice broadcasts. The process is expected to significantly reduce delays in producing NWR broadcasts and should have a positive impact on getting earlier warnings out to the NWR listening public and to emergency managers and the broadcast media who monitor NWR reports.

In addition, the NWS is beginning a program to build grass roots support for placing NOAA Weather Radio receivers in local schools and other public gathering places. The program will center around locally-formed NWR committees comprised of civic-minded leaders whose main goal will be to find funding sources to place NWR receivers in schools to give administrators fast access to changing weather conditions and severe weather alerts issued by their local NWS office.

Finally, the NWS has reached an agreement with King Features Syndicate to use nationally-syndicated comic strip character Mark Trail as the campaign symbol for educating the public about the National Weather Service's NOAA Weather Radio program. Mark Trail will appear on posters and in other educational materials to help raise public awareness levels about the benefits of owning a NOAA Weather Radio receiver equipped with an alarm tone and SAME-capability.

Specific Area Message Encoding (SAME) and FIPS Information

The newest warning alarm radios can decode the Specific Area Message Encoding (SAME) signal which accompanies each watch or warning message. The digital signal or "burst", repeated three times, contains information about the type of message, the counties affected, the length of time the message is in effect, and the source of the message. In order for each SAME-equipped NOAA Weather Radio to work properly, it will be necessary for the owner to "program" the radio for the proper codes. SAME

The identifying codes, called FIPS numbers which stands for Federal Information and Processing Standards, should be programmed into a receiver according to the instructions accompanying the radio. While it will depend on a number of factors, it would probably be a good idea to include warnings for an adjacent county especially when located near a county border. The SAME receiver pictured here has an 8-character LCD which displays items such as channel numbers and alert status descriptions (TORNADO WARNING, FLOOD WATCH, etc.) It also includes different-colored alert status indicators that let you determine at a glance the type of alert received (red for warning, yellow for watch, and green for statement).

FIPS code The table below shows the individual FIPS codes for each county in Eastern Oklahoma and Northwest Arkansas in alphabetical order. The full indentifier for each county is a 6-digit number; the first digit for the county subdivision (this number should be set to 0; numbers 1 through 9 are NOT yet being used, the next two digits are the FIPS identifier for the state (Oklahoma is 40, Arkansas is 05), and the last three digits are for individual counties. So the full 6-digit FIPS number for Tulsa County, shown to the left, is 040143.
