NOAA Weather Radio All Hazards is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service office. This network broadcasts official Weather Service warnings, watches, forecasts and other hazard information 24 hours a day, 7 days a week.  

The network carries the "All Hazards' label because it has become a single source for comprehensive weather and emergency information. While the NOAA Weather Radio system predominately broadcasts weather related information including warnings for dangerous weather events such as tornadoes and hurricanes, it also broadcasts alerts on natural disasters (like earthquakes or floods), terrorist attacks, missing person (AMBER) alerts, nuclear power plant emergencies, maritime accidents and chemical releases.  

This nework includes 1000 transmitters, covering all 50 states, adjacent coastal waters, Puerto Rico, the U.S. Virgin Islands, and the U.S. Pacific Territories. The receive these broadcasts, a weather radio or special reciever/scanner is required because normal AM/FM radios cannot pick up these high frequency broadcasts.  Broadcasts are found in the VHF public service band at these seven frequencies (MHz):
