The NOAA Public Alert Radio System

Owned by the U.S. Government and operated by a staff trained to address emergencies, the NOAA Public Alert Radio is a service of the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Department of Commerce. NOAA personnel use information from Doppler radar, storm spotters, state and local officials, satellites and other sources to issue weather watches and warnings. These watches and warnings are broadcast over NOAA Public Alert Radio and also are retransmitted by many local radio and television stations.  With this information, local emergency management and public safety officials can activate local warning systems to alert communities of an impending weather threat.
