NOAA Weather Radio (NWR) is the official voice of the National Weather Service. As such, it is important that the NWR broadcasts adhere to the highest standards of timeliness, completeness and accuracy. The objective of NWR is to provide a continuous flow of timely and accurate weather and hydrologic information directly to listeners in the service area of the NWR transmitters.

Each transmitter has a normal range of 35 to 40 miles, but with high quality receiver and antennas, the signal can be picked up at greater distances. The broadcasts can be heard on special weather radio receivers programmed to pick up frequencies between 162.400 and 162.550 MHz, and on scanners with a special weather band. Weather radios can be purchased at most electronic stores and average between $20 and $70.

One of the most beneficial features of NWR is that when a severe weather warning is issued by the National Weather Service in your area, a tone alarm is also transmitted so that your weather radio will put out an audible alert to notify you that a severe weather warning will follow. In addition, NOAA Weather Radios are now being equipped with a new technology called SAME, which stands for Specific Area Message Encoder. This will allow you to program your weather radio to alarm only for the counties that you select. (Look below for SAME codes for your county and others.)
