Ah, I can see I sort of assumed that, given that I was born, raised in and have retired to an area a hair's breath from the US Tornado Alley, as we were recently reminded: https://en.wikipedia.org/wiki/2011_Joplin_tornado https://en.wikipedia.org/wiki/2011_Joplin_tornado. We're deadly serious about Civil Defense, and at least the main news/talk station has what's needed, is for example always on the air live with useful info when there's a Tornado Warning. On the other hand, even if all the things you list aren't in place, if you have the basic infrastructure including massive penetration of receivers you can jury rig the rest given a little time and luck.
