How does this work?
The NOAA Site explains NOAA Weather Radio this way:
NOAA Weather Radio All Hazards (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from a nearby National Weather Service office. NWR broadcasts National Weather Service warnings, watches, forecasts and other hazard information 24 hours a day.
WeatherSnoop® 4 is a complete and practical weather station management software for Mac. It allows monitoring the data from the weather station in real time, storing it in a permanent database, producing graphs and detailed reports, posting it to the Internet and exporting it to most spreadsheets. WeatherSnoop has two main roles: rst, it acts as a consumer, collecting weather data from either a personal weather station or an Internet-based data source. The WeatherSnoop Plugin allows you to create Weather Station devices. To create a new one, switch to the device view and click the New button. This will bring up the device edit dialog. Select Plugin from the Type: popup. Select WeatherSnoop from the Plugin: popup, and select WeatherSnoop 2 Weather Station from the Model: popup.

Working with the Federal Communication Commission's (FCC) Emergency Alert System , NWR is an 'All Hazards' radio network, making it your single source for comprehensive weather and emergency information. In conjunction with Federal, State, and Local Emergency Managers and other public officials, NWR also broadcasts 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).
Known as the 'Voice of NOAA's National Weather Service,' NWR is provided as a public service by the National Oceanic and Atmospheric Administration (NOAA), part of the Department of Commerce. NWR includes more than 940 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, 162.425, 162.450, 162.475, 162.500, 162.525, 162.550
Saratoga-Weather.org operates a Midland WR300 NOAA Weather Radio set to Channel 7 (162.55MHz) to receive NOAA station KEC49 broadcasting from Mt. Umunhum with 300 Watts of power. The audio output of the radio is fed to the line-input on the sound card for the weather station PC. Software by edcast (now altacast) encodes a 16Kbps monaural MP3 stream and sends it to the NOAAWeatherRadio.org. NOAAWeatherRadio.org then makes the stream accessable world-wide.
We also have a small Raspberry Pi3 with a Software Defined Radio USB that runs darkice and icecast to stream the WWF64 Monterey Marine stream both locally and at NOAAWeatherRadio.org.
Special thanks to Mike and Chris for establishing the the new common stream host now that WeatherUnderground has discontinued offering their streaming NOAA Radio service in January, 2017.
