Silicon Laboratories makes an IC Weather Band (WB) radio called the Si4707. This IC is capable of using the specific area message encoding (SAME) and also supports the detection of the 1050Hz alert tone that is used by the National Weather Service. Currently no Arduino shields exist that could be used in a manner to receive, use, and/or display the broadcast alert data such as severe thunderstorm or tornado warnings. I think a shield like this would be great to implement all kinds of interfaces to this publicly available data resource. Some examples include Twitter alert system, VOIP streaming of audio broadcasts to your cellphone, and even a radio
