Topic Description

General Description

NOAA Weather Radio All Hazards (NWR) is a nationwide network of 1000+ radio stations broadcasting official National Weather Service weather, warnings, watches, forecasts and other alerts and hazard information 24 hours a day, 7 days a week directly from the nearest National Weather Service office.  Geographic coverage of NWR broadcasts include most of the continental United States, Alaska, Hawaii, Puerto Rico, Guam, Saipan, American Samoa, and the Virgin Islands (including adjacent coastal waters). See specific “Coverage Maps.”

These broadcasts known as the "Voice of NOAA's National Weather Service” are VHF-FM public service band radio broadcasts that use high frequency transmitters (100W, 300W, and 1000W) broadcasting up to 40 miles from the designated tower; using one of seven discrete frequencies between 162.400 and 162.550 MHz.

NOTE:  Normal FM radio receivers (88 MHz – 108 MHz) cannot receive these NWR broadcasts.  Specific radio receivers have been designed to receive these NWR broadcasts (also referred to as Weather Band or WB).  Additionally some of these radio receivers may only have one, three, five or all seven NWR frequencies.  Most marine radio receivers and some CB radios are configured to receive NWR broadcasts identifying channels as Wx/WB/or NOAA Channels 1-7.
