Weather Radio (NOAA Weather Radio - NWR)
Whether you are boating, hiking, camping or just at home, getting the latest news of breaking weather conditions can be very important. The National Oceanic and Atmospheric Administration (NOAA) offers via the  National Weather Service NOAA Weather Radio (NWR). NWR is a network of radio stations that continuously broadcast weather and other emergency information.

History
The Weather Bureau first began transmitting aviation weather in the 1950's from 2 sites. This agency later became the National Weather Service and in the 1960's expanded service to include information for maritime operations. By the end of the 1970's, the NOAA Weather Radio (NWR)  network included over 300 transmitters. As of 2001 there were over 600 stations transmitting covering over 90% of the United States.

What Is Broadcast
The programming on NWR originally covered weather and natural related incidents such as tornados, hurricanes, floods, thunderstorms, earthquakes and volcanic activities. It was expanded to include man-made emergencies such as hazardous chemical releases, oil spills, nuclear power plant related emergencies as well as train derailments and maritime accidents. Most recently, NWR bills itself as an all-hazards public warning system with information broadcast directly to the public 24/7. The newest information includes information in the event of a terrorist attack and Amber Alerts if requested by local law authorities.

How to Receive Broadcasts

Seven frequencies have been set aside by the FCC for the NWR network, but these stations cannot be received with standard radios. The broadcasts are allocated on frequencies higher than standard FM radios can receive . The frequencies are:
 

162.400
MHz

162.425
MHz

162.450
MHz

162.475
MHz

162.500
MHz

162.525
MHz

162.550
MHz


Many scanners and shortwave radios are able to tune to these frequencies. Some FM radios are equipped with a weather (WX) band and there are also radios dedicated to tune to weather radio stations.

Local Reception
Locally, coverage has improved in the Litchfield County area of Connecticut thanks to a transmitter located on Cornwall Mountain in Cornwall, CT. That station's call sign is WWH33 and broadcasts on 162.500 MHz. The station's programming is handled by the National Weather Service's office in Albany, NY. Coverage maps are available for transmitting locations that offer service to Connecticut:
 

NWR Coverage maps for other parts of the country can be found at this NOAA Weather Radio page.

         
Weather Alert
In addition to continuous broadcasts, coded alerts can be broadcast to weather radios which will cause the radios to sound an alarm. This system is reliable, but prone to false alarms since an alarm is sounded whenever it is needed in the transmitter's service area. Most radios currently produced support a newer technology for weather alerts.

Newest Technology
Specific Area Message Encoding (SAME) technology allows the NWR system to broadcast localized messages for areas affected by emergency warnings and alerts. This allows radios to be designed to sound alerts and show the specific alert. Receivers can be programmed to enable alarms for specific regions.
Weather radios designed for home use often include battery back-up as well as a clock in the event of a power failure.

Specific Area Message Encoding (S.A.M.E.) Location ID Codes
Since SAME alerts are designed for specific areas, the receiver must be programmed for the location where it will be used.  Programming instructions vary by model, but they all use the same 6 digit SAME code for a given area. Care must also be taken to use a NWR frequency designated for a given area.  For Connecticut counties, the codes are:
 
County SAME code Frequencies   County SAME code Frequencies
Fairfield 009001 162.500
162.400
162.550
  New Haven 009009 162.500
