|NOAA is the National Oceanic and Atmospheric Administration. It was created in 1970 under the Department of Commerce by combining a number of different bureaus and services, such as the U.S. Weather Bureau, the National Satellite Center, and the Bureau of Commercial Fisheries. The main NOAA web page can be found at http://www.noaa.gov/.
NOAA Weather Radio (or NWR) is a public service provided by NOAA as an "all hazards" radio network. In addition to broadcasting weather alerts, NWR also sends non-weather alerts, for both natural and man-made hazards.
