NOAA Weather radio broadcasts are made on frequencies in the high band FM ranging from 162.400 to 162.550 MHz. Unfortunately these frequencies are not found on the average home radio now in use. However, a number of radio manufacturers offer special weather radios that operate on these frequencies. Some of these radios offer a special tone alert feature which automatically sounds a loud tone and turns the radio on when life and/or property are in danger. The NWR weather warning signals from the NWS offices nationwide now are transmitted with WRSAME technology which allow for the warning of just one county instead of the entire broadcast area.
