What I do is I have a scanner plugged into my board tuned to the strongest NOAA station. In event of a weather emergency I will listen to another scanner (I have 3) to listen for the tones or important information. The second those tones start to sound All it takes is a flip of a switch on my board to interrupt programming and put the message on.
It might not be automatic, but it does work.
