NOAA Weather Radio broadcasts National Weather Service warnings, watches, forecasts and other hazard information 24 hours a day.
Working with the Federal Communications Commission's new Emergency Alert System, NOAA Weather Radio is an "all hazards" radio network, making it the single source for the most comprehensive weather and emergency information available to the public.
NOAA Weather Radio also broadcasts warning and post-event information for all types of hazards - both natural (such as earthquakes and volcano activity) and technological (such as chemical releases or oil spills).
Known as the "Voice of the National Weather Service," NOAA Weather Radio is provided as a public service by the Department of Commerce's National Oceanic & Atmospheric Administration.
The NOAA Weather Radio network has more than 550 transmitters, covering the 50 states, adjacent coastal waters, Puerto Rico, the U.S. Virgin Islands, and the U.S. Pacific Territories.
NWR requires a special radio receiver or scanner capable of picking up the signal.
Broadcasts are found in the public service band at these seven frequencies(MHz): 162.400 162.425 162.450 162.475 162.500 162.525 162.550
