can somebody clarify that this isn't an actual warning, just saying that his intel knows it's getting close?

I saw Mitchell posting days before the quake last year and I was literally shocked when it happened. I remembered somebody called the prediction but could never remember the name... mitchell coombes that's exactly correct

if he says we've got 100+ hours before a major west coast tsunami I will believe it. what's the best case scenario, he's wrong? he wasn't wrong about japan.
