The thing is though - what do you expect Joe Public to do?
I went to Atlanta last year during the horrendous tornado outbreak across the Deep South - had to ask an American friend, what the hell do you do if a tornado warning is issued. Luckily nothing serious materialised in my area apart from a few severe thunderstorms, however locations I travelled to the next day certainly did.
We, rightly, aren't prepared for such an occurance. Today was probably a Q50 event.
