< < < Play Radio So what is this all about? This personal weather station and many more volunteers have taken a NOAA Weather Alert radio and fed it into a computer. We then take that feed and upload or "stream" it live to our partner Weather Underground. They have graciously donated a server and large amounts of bandwidth to streaming these broadcasts over the internet, so you the public can be kept better informed in case of emergencies. How NOAA Alert actually works is better described below from a reprint from their website.
