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

NWR works with the Federal Communication Commission's (FCC) Emergency Alert System , and is an "All Hazards" radio network.  This makes NWR your single source for comprehensive weather and emergency information. In conjunction with Federal, State, and Local Emergency Managers and other public officials, NWR also works with Federal,State, and Local Emergency Managers to broadcast warning and post-event information for all types of hazards – including natural (such as earthquakes or avalanches), environmental (such as chemical releases or oil spills), and public safety (such as AMBER alerts or 911 Telephone outages).

NWR is provided as a public service by the National Oceanic and Atmospheric Administration (NOAA).  NWR includes 1000 transmitters, covering all 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 VHF public service band at these seven frequencies (MHz):

• 162.400

• 162.450
