Whilst I suspect there is some hyperbole to try and stress the point that it isnt safe and nobody is coming for them until it has blown over. It is striking to see how many are defying official warnings. I think its a mixture. Some of it will be plain stupidity or stubbornness. Some will have nowhere to go, or just wont have the means to escape. Some will be living on higher ground within the local area or living in Hurricane rated dwellings. I cant be too critical of them, as if I was in that position, as long as I wasnt in the immediate storm surge area I'd probably ride it out myself.
